WIRELESS
CONNECTION CHECK UP
-Make sure
that the configuration utility is installed on EACH wireless computer.
-Make sure
the wireless pc cards themselves are working properly.
Set 2
wireless computers to adhoc, ssid
is "linksys" all lowercase, wep is disabled, and select channel for both. Put them within 15 feet of each
other. Modify tcp/ip for 1 wireless adapter to have an ip of 192.168.1.10 and subnet of 255.255.255.0 and the
other wireless adapter to be 192.168.1.11 and subnet of 255.255.255.0. Restart the computer if necessary. When that is done, see if they can ping
each other. Go click on Start>Run>type
"command" at the open box and <enter>. At the command prompt, type "ping
192.168.1.10" and see if you get a "reply...”. Do it again, and type "ping
192.168.1.11".
If you do
get a reply for both instances, the cards are good.
-Now, let's
make sure the router is good. Make
sure the wireless computers are within 15 feet of the router. Set the cards to infrastructure, ssid is "linksys" all
lowercase, wep is disabled.
-Now, reset
the router by doing the following:
Hold
the reset button and keep holding it down.
Unplug
the power from the router and wait 5 seconds.
Plug
the power back on and wait another 5 seconds.
Now,
let go of the reset button
-Remove ALL
tcp/ip protocols for any
WIRED network adapters installed on the systems that are wireless.
-Reboot the
computer when all this is done.
-When
rebooted, run the configuration utility and check to see if you have a signal
strength and link quality. If you
do, you have communication with the router. Check to see if you can ping the router
by clicking on Start>Run> type "command" at the open box and
<enter>. Type "ping
192.168.1.1" at the command prompt and check to
see if you get a "reply...” If you do, then you have good wireless
communication with your router. You
can check the DHCP on the router by going back to the tcp/ip properties for the wireless cards and setting
everything back to obtain an ip address
automatically. Make sure also that
there is nothing in the gateway tab, and in the dns
configuration tab, it is disabled.
Reboot the computer if it asks you to after making the changes.
-When the computer is rebooted again, check in your
configuration utility to see if you still have signal strength and link
quality. If you do, check winipcfg or ipconfig in DOS for
an ip address.
Your ip should be in the 192.168.1.xxx
range. If it is, see if you can
ping the router. If you get a
"reply..." your router is working properly on the LAN side. Now you should be able to get into the
router's web based utility and configure the WAN side.
WIRELESS LAN (IEEE 802.11b) FREQUENTLY ASKED QUESTIONS:
My Instant Wireless equipment does not have very good range.
There is no way to know the exact
range of your wireless
network without testing.
Factors such as Leaded glass, metal, reinforced
concrete floors and walls may inhibit the signal and reduce range. Other
factors that can reduce distance are unshielded house wiring and fluorescent
lighting.
Start with your Access Point and your wireless PC or Laptop in the same room
and move away in small increments to determine the maximum range in your
environment.
What frequencies are
used to operate Instant Wireless equipment?
Instant
Wireless
equipment uses DSSS [Direct Sequence Spread Spectrum] technology. In
Channel 1 - 2.412GHz
Channel 2 - 2.417GHz
Channel 3 - 2.422GHz
Channel 4 - 2.427GHz
Channel 5 - 2.432GHz
Channel 6 - 2.437GHz
Channel 7 - 2.442GHz
Channel 8 - 2.447GHz
Channel 9 - 2.452GHz
Channel 10 - 2.457GHz
Channel 11 - 2.462GHz
Can I run an application from a remote computer over the
wireless network?
This will depend on whether or not the application is designed to be
used over a network. Consult the application’s user guide to determine if
it supports operation over a network.
Can I play
multiplayer games with other users of the wireless network?
Yes, as long as the game supports
multiple players over a LAN (local area network). Refer to the game’s
user guide for more information.
What is the IEEE 802.11b standard?
The IEEE 802.11b Wireless LAN
standards subcommittee is formulating a standard for the industry. The
objective is to enable wireless LAN hardware from different manufacturers to
communicate.
What IEEE 802.11
features are supported?
The product supports the following
IEEE 802.11 functions:
• CSMA/CA plus Acknowledge
protocol
• Multi-Channel Roaming
• Automatic Rate Selection
• RTS/CTS feature
• Fragmentation
• Power Management
An Ad-hoc wireless LAN is a group of
computers, each with a WLAN adapter, connected as an independent wireless LAN. An
Ad-hoc wireless LAN is applicable at a departmental scale for a branch or
An integrated wireless and wired LAN
is called an Infrastructure configuration.
Infrastructure is applicable to
enterprise scale for wireless access to a central
database, or wireless application
for mobile workers.
A specific Ad-hoc LAN is called a
Basic Service Set (BSS). Computers in a
BSS must be configured with the same
BSS ID.
An Infrastructure configuration
could also support roaming capability for mobile workers. More than one BSS can
be configured as an Extended Service Set (ESS). Users within an ESS could roam
freely between BSSs while maintaining a continuous
connection to the wireless network stations and Access Points.
The FCC and their
counterparts outside of the
WEP is Wired Equivalent Privacy, a data
privacy mechanism based on a 40 bit shared key algorithm, as described in the
IEEE 802.11 standard.
Frequency Hopping Spread Spectrum
(FHSS) uses a narrowband carrier that changes frequency in a pattern that is
known to both transmitter and receiver. Properly synchronized, the net effect
is to maintain a single logical channel. To an unintended receiver, FHSS
appears to be short-duration impulse noise. Direct Sequence Spread Spectrum
(DSSS) generates a redundant bit pattern for each
bit to be transmitted. This bit pattern is called a chip (or chipping code).
The longer the chip, the greater the probability that the original data can be
recovered. Even if one or more bits in the chip are damaged during
transmission, statistical techniques embedded in the radio can recover the
original data without the need for retransmission. To an unintended receiver,
DSSS appears as low power wideband noise and is
rejected (ignored) by most narrowband receivers.
Would the
information be intercepted while transmitting on air?
WLAN features two-fold protection in
security. On the hardware side, as with Direct Sequence Spread Spectrum
technology, it has the inherent security feature of scrambling. On the software
side, the WLAN series offers the encryption function (WEP) to enhance security
and access control. Users can set it up depending upon their needs.
Roaming is the ability of
a portable computer user to communicate continuously while moving freely
throughout an area greater than that covered by a single Access Point. Before
using the roaming function, the workstation must make sure that it is the same
channel number as the Access Point of the dedicated coverage area.
To achieve true seamless
connectivity, the wireless LAN must incorporate a number of different
functions. Each node and Access Point, for example, must always acknowledge
receipt of each message. Each node must maintain contact with the wireless
network even when not actually transmitting data. Achieving these functions
simultaneously requires a dynamic RF networking technology that links Access
Points and nodes. In such a system, the user’s end node undertakes a
search for the best possible access to the system. First, it evaluates such
factors as signal strength and quality, as well as the message load currently
being carried by each Access Point and the distance of each Access Point to the
wired backbone. Based on that information, the node next selects the right
Access Point and registers its address. Communications between end node and
host computer can then be transmitted up and down the backbone.
As the user moves on, the end node’s
RF transmitter regularly checks the system to determine whether it is in touch
with the original Access Point or whether it should seek a new one. When a node
no longer receives acknowledgment from its original Access Point, it undertakes
a new search. Upon finding a new Access Point, it then re-registers, and the
communication process continues.
Frequently Asked Questions
WIRELESS NETWORK ADAPTER FREQUENTLY ASKED QUESTIONS:
How do I set my Instant Wireless
Adapter back to original settings?
If you want
to start over and set your Wireless PC Card to the factory defaults, load the
Configuration Utility and click on the Restore Defaults button.
My
WPC11/WDT11 equipped computer cannot see the rest of my network when using an
access point.
Check the card's Mode in the
LAN Configuration Utility Configure page. This should be set to
Infrastructure.
Check the SSID in the LAN Configuration Utility Configure page. This
value should match the access point's.
Once these settings have been verified, go to the Link Info tab in the LAN
Configuration Utility. There should now be bars indicating that there is
a connection with the access point.
My Motherboard
supports Dual Pentium III processors and the WDT11 is not working correctly.
Dual Processor boards have an
option in the BIOS for MPS [Multi-Processor Support]. This can run in 2
modes, MPS1.4 and MPS1.1.
MPS1.4 adds an additional 8 IRQ, for a total of 23. This is where the
issue lies. If the WDT/WPC11 falls on one of these IRQ, it will not
function properly. This is not dependent of the actual number of physical
processors installed in the machine. The problem has been replicated on
single and dual processor environments with these boards.
In order for the card to function correctly, the setting needs to be MPS1.1,
which uses the standard allotment of 15 IRQ.
Win XP
Wireless Configuration Utility:
To get to the screen, go to Start>Control
Panel>Network and Internet Connections>Network Connections and then right
click on Local Area Connection then go to Properties.
WIRELESS
ACCESS POINTThere is an
issue with the WAP11's SNMP manager and saving an ip
address with two digits in the fourth octet.
For example, if you are trying to save the WAP11's IP address as
192.168.0.10, it would be saved as 192.168.0.100 instead.
The USB Configuration Utility does not have this problem.
If needing to set the address to end in a number lower than 100, it is
recommended to use the USB Configuration Utility or download the most recent
SNMP utility from our website at www.Linksys.com.
When using
the WAP11 with a BEFW11S4, the DHCP IP range must be increased on the BEFW11S4
to accommodate the IP addresses of the WAP11 and it's wireless clients.
An example of this would be if a WAP11 was added to support roaming, as in a
small office environment. On the BEFW11S4's DHCP page, the DHCP range
could be edited as follows:
DHCP Server: Enable
Starting IP Address:
192.168.1.100
Number of DHCP Users:
149 [By default, this is 50.]
This setup
would be used for a WAP11 that had the default address of 192.168.1.250.
Changing the address of the WAP11 to within the default 192.168.1.100 -
192.168.1.150 range also works.
If one of
the above configurations is not changed, the WAP11's wireless clients will not obtain an
IP address from the BEFW11S4.
Yes, with some exclusions. Any
aftermarket antenna that does not put additional current to the connection port
will not void the warranty. The use of an externally powered antenna will
void the WAP11's warranty. But please be reminded that Linksys do not support
such a set-up.
Can the Access
Point act as my DHCP Server?
No. The
Access Point is nothing more than a wireless hub, and as such, cannot be
configured to handle DHCP capabilities.
The WAP11 unit comes with a
default IP address of 192.168.1.250 and a subnet mask of 255.255.255.0.
In order to access the unit with the provided SMNP Manager software, the
machine connecting to the WAP11 must have an address within the same segment,
such as 192.168.1.248. We recommend that you use a static IP address on the
computer using the SNMP Manager.
Reverse-polarity
TNC.
Using a
straight through cable, connect the Access Point to a standard port on your hub
or switch. Do not connect to the uplink port of that hub or switch using
a crossover cable, as this will not work. The maximum uplink distance to
a 10/100 switch or a 10Mbps hub is 100 meters or 328 feet.
Multiple
access points can be used on the same LAN, provided they are attached to the
same hubs or switches that are connected by Cat 5 ethernet
cable.
The channel for each access point should be unique, within the range of 1-11
for
Example: 3 - 6 - 9 - 2 - 5 - 8 - 11 - 1 - 4 - 7 – 10
The SSID should be the same for all the units on the LAN
If WEP is enabled, all WAP11 units must have the same algorithm, passphrase, keys, and tx key in
order for the wireless
equipped machines to roam.
During the
installation, the software may have incorrectly identified your operating
system.
To check for this error, look in "C:\PROGRAM FILES\LINKSYS\CONFIGURE
UTILITY\" for a file named NDCAGT9X.VXD.
If this file exists, rename it to NDCPRTNS.SYS and reboot your system.
This will eliminate all the errors and the computer should boot normally from
now on.
When
enabling the Wireless
portion on the setup page and applying the settings, if an error message window
appears stating 'Channel out of range [14~14]', click OK.
The Settings are successful window should appear afterwards, and upon
refreshing the Setup page the Wireless will now be enabled.
This error message should not appear again.
How could I
reset the WAP11 to factory default settings?
You need
to access the WAP11 using the USB Config Utility or
the SNMP Utility. Then on the Status Tab, click the Restore Defaults button. A
window will appear asking if you want to continue with the process.
Just click
yes and to continue. Wait for the utility to reconnect with the access point.
How could I
reset the BEFW11S4 Router to its factory default?

128 bit WEP
devices can be used
with 40 or 64 bit WEP devices as long as the device driver has a way to set the
lower encryption level. Encryption level is determined by the encryption key length. If a device is
capable of 128-bit encryption, it's inherently capable of 40-bit, unless the
vendor decides for some reason to not allow the lower encryption level
64 bit WEP
is the same as 40 bit WEP! The lower level of
WEP encryption uses a 40 bit (10
Hex character) "secret key"
(set by the user), and a 24 bit
"Initialization Vector" (not under user
control). Some vendors refer to this level of WEP as 40 bit, others as 64
bit. Either way, they're the same encryption level and can interoperate.
The higher level of WEP
encryption, commonly referred to as 128
bit WEP, actually uses a 104
bit (26 Hex character) "secret
key" (set by the user), and a 24 bit "Initialization Vector"
(not under user control).
The methods for entering WEP codes
are confusing enough, but it gets worse if you are trying to get wireless
products from different manufacturers to work together! A particularly
tricky combination is products based on the Lucent/WaveLAN drivers (
The key to
success is to pay attention to the WEP
key formats that must be used for each product.
The Lucent based products
typically require you to enter the WEP key in either ASCII or Hexadecimal (Hex)
format. The default is ASCII, i.e. regular alpha-numeric
characters. If you want to use Hex format, you must start the code with
"0x" (that's
the number zero and a lower-case "x"). A typical WaveLAN
based WEP setup screen is shown below.
In this example, Keys 1, 2, and 4 use ASCII format and Key 3 uses Hexadecimal.
Now look at this typical Intersil PRISM WEP client setup screen. This example
is from a Client card that allows either 64 or 128 bit WEP.
Two methods can be used:
1) Passphrase Method: This method
generates a Hexadecimal key
from an ASCII string that you enter. This is not the same as directly entering an ASCII key!
2) Manual Entry Method: This
method requires you to enter a 10 character Hexadecimal key for 64-bit WEP, and a 26 character Hexadecimal key for 128-bit WEP. (The
"Manual Entry" input area changes to accommodate the larger key.)
The simplest way to get these two
products to work together is to use
Hexadecimal keys, since that method is common to
both.
TIPS and HINTS for WEP
Encryptions:
Tip #1: Remember
to use the "0x"
prefix to indicate Hexadecimal
Tip #2: Make
sure your card can support the WEP level that you are trying to set!
Tip #3: Remember
to enter the correct number of
characters for the desired encryption level in the Lucent WEP
Setup window. Use the pop-up WEP Code Summary if you forget how
many characters you need to use.
IEEE 802.11a
Wireless LAN Standard FREQUENTLY ASKED QUESTIONS:
What is the IEEE
802.11a standard?
The IEEE 802.11a Wireless LAN
standards subcommittee formulates WLAN standard for the industry. The objective
is to enable wireless LAN hardware from different manufacturers to communicate.
The product supports the following IEEE 802.11a functions:
• OFDM protocol
• Multi-Channel Roaming
• Automatic Rate Selection
• RTS/CTS feature
• Fragmentation
Would the information be intercepted while transmitting
on air?
WLAN features two-fold protection in security. On the hardware side, as
with Direct Sequence Spread Spectrum technology, it has the inherent security
feature of scrambling. On the software side, the WLAN series offers the
encryption function (WEP) to enhance security and access control. Users can set
it up depending upon their needs. WEP under Linksys IEEE 802.11a supports 64,
128 and 152 bit encryption.
Are 802.11a and 802.11b products compatible?
No. These products use different frequencies - 5GHz and 2.4GHz
respectively.
Will 802.11a (5GHz) interfere with my 802.11b (2.4GHz)
Access Point?
No. Because their signals travel in different frequency bands, one
significant benefit is that they will not interfere with each other.
IEEE 802.11a Wireless Access Point
Using multiple Access Points on the
same channel and in close proximity to one another will generate interference. When
employing multiple Access Points, be sure to operate each one on a different
channel (frequency). It is
recommended that channel setting for each access point is separated by a
multiple of 2.
How do I reset the Access Point?
The WAP54A access point is equipped
with a reset button on its rear panel. Unlike with the WAP11 access
point which do not have one, and reset is done through the configuration
utility. Press the Reset button on the back of the WAP54A Access Point
for about ten seconds. This will reset the unit to its default settings.
How do I resolve issues with
signal loss?
There is no way to know the exact
range of your wireless network without testing. Every obstacle placed between an
Access Point and wireless PC will create signal loss. Leaded glass, metal,
concrete floors, water and walls will inhibit the signal and reduce range.
Start with your Access Point and your wireless PC in the same room and move it
away in small increments to determine the maximum range in your environment.
You may also try using different
channels, as this may eliminate interference affecting only one channel. Also,
due to FCC regulations, more power may be transmitted on channels 52, 56, 60
and 64, than on the lower channels. Lastly, check the Advanced tab of
the Web-Based Utility and make sure that FULL is selected in the Transmission
Rate field.
Turbo mode allows high-speed
connections, but severely limits range. Turbo mode must be enabled on both the
Access Point and the wireless PCs to function. Turbo mode is not compatible
with Windows XP and may only function with Linksys 5GHz wireless adapters.
Does the Turbo Mode work with Windows XP PCs?
No. The Turbo Mode does not work with Windows XP PCs.
Does the Access Point function as a firewall?
No. The Access Point is only a bridge from wired Ethernet to wireless
clients.
I have excellent signal strength, but I cannot see my
network.
WEP is probably enabled on the Access Point, but not on your wireless
adapter
(or vice versa). Verify that the same WEP Keys and levels (64, 128 or
152) are
being used on all nodes on your wireless network.
What is the maximum number of users the Access Point
facilitates?
No more than 65, but this depends on the volume of data and may be less
if many users create a large amount of network traffic.
How many channels are available with the Access Point?
There are eight available channels (frequencies) ranging from 5.15GHz to
5.32GHz.
What is the difference in range between 802.11a and 802.11b
products?
Overall, range will be a little less in a typical
environment, while higher speeds may be achieved with 802.11a, throughput
degrades more quickly. Note that wireless range is a function of transmit power
output, frequency used and environmental conditions. Increasing this factor
generally decreases over-all range and even data throughput.
Will the Access Point be subjected to interference from my
microwave or cordless phones?
No. Since the Access Point operates in the uncrowded
5GHz band, there is less interference than ever. The Access Point also has an
"Auto Select" feature that scans for clear channels.
Can I use wireless adapters from other vendors to connect to
the Linksys Access Point?
Yes. Any wireless adapter that adheres to the IEEE 802.11a standard
should function with the Access Point.
The WAP54A has the following default
settings:
LAN:
AP Name: Linksys
WAP54A
LAN IP address: 192.168.1.252
Subnet Mask: 255.255.255.0
Wireless:
Turbo Mode: Off
SSID: linksys
Channel: 5.2528 GHz
WEP: Disabled
Web utility
User: name: blank
Password: admin
As of this time, bridging is not supported on the access point. Linksys
is currently considering this feature through a firmware upgrade.

My computer does
not recognize the Wireless PC Card.
Make sure that the Wireless PC Card
is properly inserted into the PCMCIA slot. Note that the card can be inserted
either way, but is correct only when it is inserted so that the “Instant
Wireless” logo on the front of the card cannot be seen. If in doubt, try
inserting the card both ways. The card will slide in further when it is
correct.
The Wireless PC Card does not
work properly.
• Reinsert the Wireless PC
Card into your notebook’s PCMCIA slot. A beep should be heard if the card
is properly inserted. The Link LEDs should be facing
upward for correct insertion of the PC card on the PC slot.
• For non-Windows
environments, make sure that a PCMCIA card service driver is installed on your
PC.
• Open the Control Panel and
click on the PC Card. Check whether it has a PCMCIA card in one of the
sockets or not. If you find the Network PC Card in one of the sockets, it means
the card has been detected properly. If you see a yellow question mark, the
resources are conflicting.
• Right-click on My
Computer and select Properties. Select the device manager and click
the Network Adapter. You will find the Wireless PC Card if it is
installed successfully. If you see the yellow exclamation mark, the resources
are conflicting. Click PCMCIA card and then click PCMCIA card service.
You will see the status of the Network PC Card. If there is a yellow question
mark, please check the following:
• Make sure that your notebook
has a free IRQ.
• Make sure that you have
inserted the right card and installed the proper driver.
If the Network PC Card does not
function after attempting the above steps, remove the card and do the
following:
• Uninstall the driver
software from your PC.
• Restart your PC and repeat
the hardware and software installation as specified in this User Guide.
• Make sure that the notebook
PC is powered on.
• Make sure that your Wireless
PC Card is configured on the same channel and with the same security options as
the other computers in the Infrastructure configuration.
The Security
Page of the BEFW11S4 is found on newer firmware versions starting with 1.40.3,
contrary to what the manual says.
When I insert a WPC11 v3.0
to my BEFSR41W, the DIAG LED turns on.
BEFSR41W
is originally intended to use only WPC11 v2.5. You have to upgrade firmware to
version 11R14 to be able to use the WPC11 v3.0 as the wireless engine of the
router.
Will the WAP11 communicate with a BEFW11S4 or other
routers with wireless capabilities?
The WAP11 will only communicate with
another WAP11 from Linksys.
How many
wireless clients can Linksys’ wireless network support?
Linksys wireless network can have up
to 32 wireless nodes as clients.
How would you determine the version of the WPC11 wireless
cards? How about WUSB11 versions?
For WPC11, version number is written
on the wireless card itself. If you can’t find any number/version
written, it means it is the original version.
For WUSB11, the original version
doesn’t have an external antenna. Version 2.5 has external antenna, and
so as the version 2.6, but version 2.6 has “2.4GHz” written beside
the LEDs.
What
versions of WPC11 can I use with WDT11?
WDT11 is designed for use with the
original version of WPC11, but with the new WDT11 driver, all versions of WPC11
can be used. Download the WDT11 driver from the Linksys website and install. (http://www.linksys.com/download/driver.asp?dlid=49&osid=7)
Work-around: Continuous
pinging of the other WAP11 or a node on the other side of the network may be
done so as not to make the wireless bridge idle.
Eg.
What is the function of IP Filtering
on the WAP11, its effect on the speed and encryption?
It doesn't allow other
packets to pass through like that of NetBEUI and IPX/SPX. It only allows TCP/IP
Packets. It lessens the network traffic.
What is SSID
Broadcast and its effect on the network?
This is for added security
wherein the access points stops broadcasting SSID on its beacon so that
wireless sniffers will not be able to get the SSID of the network.
Is Wireless Bridging between WAP11 and
WAP11 version 2.2 possible?
This is possible with the
newest firmware (v1.009 or 1010) of the WAP11 v2.2 which has bridging functions
and will do wireless bridging with WAP11 v1.0.
Does the WAP54A support wireless
bridging?
WAP54A does not have
bridging capability with its current firmware.
What
is SNMP Trap log on the WAP11 utility?
The trap is only used to
provide status for SNMP access.
Is it
possible to downgrade the firmware of a WAP11?
As for firmware downgrades,
we really do not support it on WAP11 v1.0.
However, F/W downgrade and
upgrade can be done in WAP11 v2.0
Downgrading
of firmware of the WPC11 card and WUSB11.
Its automatic depending on
the operating system and the version of the driver. Only for WPC11 version 3.0.
Can we change the antenna of the
wireless devices?
We should discourage our
clients to use other antenna than the antenna provided with the access point,
which is optimized for the device. It is an unsupported issue, and will void
product’s warranty.
Will VPN work over wireless
networks?
VPN session is supported
on wireless networks. Currently, VPN will not work with WEP Enabled. This may
be due to the large overhead from the encryption brought about by both WEP and VPN’s encryption methods.
Does Linksys have antenna boosters
available on the market?
As of this time, we
don’t have any available booster/ antenna available on the market.
My
WPC11 v3.0 would not communicate with a WAP11 v2.2

WPC11 version 3.0 and/or WDT11+WPC11: upgrade the WAP11 firmware to 1010
Pinging
a wireless client and no response:
Got to the configuration
of the wireless and change the RTS Threshold and Fragmentation Threshold to
2304.
Is Access Point Client Mode same as
Wireless Bridging?
Access Point Client mode
allows a network to be bridge to WAP11 configured under Access Point Mode. It
is different to bridging since the main WAP11#1 could still cater for wireless
clients on its range. This is not applicable to BEFW11S4.
Difference between the WUSB11
v2.5 and v2.6

Are the drivers for the WPC11 Zero Configuration ready?
No. The WPC11 (original WPC11 only) driver is an NDIS 5 driver so it will
support all of the new networking features offered by Windows XP. It will not
support the "Zero Configuration" utility built-in to XP. Linksys
provides an easy to use configuration utility for the wireless adapter.
I'm attached, I'm not attached.
If a wireless PC is has a weak connection to an
access point, Windows XP will constantly display "You are not
connected" and "You are Connected..." messages. These are
terribly annoying and can not be
disabled without removing Zero Config (see next
section).
No. You can disable the Zero Configuration utility by running
msconfig.exe. Remove the checkmark next to Zero Config
on the Services tab (it's at the bottom of the list).
Before you

Utility should open without any error messages. Double check the settings to
make sure that they match what was in the Local area connection
configuration.
Any changes made to the Configuration Utility will
require being saved by clicking on the Save Changes or Apply Changes
button.
Reboot the computer and check that the network agent
error no longer appears, by opening the Configuration Utility.
Another step to try is copying the file Ndcprtns.sys from the \winnt\system32 to the
winnt\system32\drivers folder. This
has been reported to work as well
WPC11Code 31 under Windows 2000
During the driver installation for the WPC11 under Windows
2000, some users may be experiencing a Code
31 error. This is due to one file being copied to the wrong directory
during installation. The file, CW10.SYS, is being copied to the System32 file folder and Windows is
unable to locate the file. The file
should be located in the Drivers subdirectory
in the System32 file folder. In order to correct this issue, the file
must be copied into the correct folder so that Windows will be able to locate
it during the installation.
To place the
file into the correct directory, do the following:
1)
Start the
Windows Explorer. Do this by
clicking the Start button, then
selecting Accessories from the menu
and then Windows Explorer.
2)
Locate the WINNT folder in the left-hand pane of Windows Explorer and highlight it. In the right hand window, all of the
folders and files in the WINNT folder will be visible. Locate the folder system32 and double click it.
3)
Locate the
file called cw10.sys and right-click
it. Choose CUT from the menu that
pops up.
4)
Locate the folder called Drivers in the same window.
Right click on the folder and choose Paste from the menu that pops up.
5)
Once this is
done, restart the PC or laptop computer.
The Device Manager will show that the WPC11 has been successfully
installed and there should be no more Code
31.
