- Make sure the account ID is not TOS
- Ask the customer to reboot the router. (Either by removing the power or by entering the command “reboot” at the router prompt)
Still the SYN is not ok then following has to done:
- Confirm the Port ID is activated by calling EIM
- If yes Sign of the port and sign on by calling PCM
2. WAN link shows ok but no browsing
This confirms that the ADSL line is fine
Still the same problem, Telnet the router or enter through management port
CBOS# sh error
If it shows authentication failure, check the username and password confirm it is active and correct. If still authentication failure report to EIM
Will show the authenticated username configured, check for the IP address also. If IP address is 0.0.0.0 then report it to EIM for further action (could be IP availability problem).
If there is a valid IP address try to ping the DNS from CBOS prompt, for no response report to EIM, if it is successful check the same from one of the computer
3. LAN link is not present
- Still problem, Check with CROSS cable directly connecting from router to PC
Make sure the existing cable is a straight cable for Hub \ Switch tot he router or check with different port on Hub \ Switch. Still the same problem advice the customer to check the Hub \ Switch
4. Ping is ok, can not
Browse
Ping indicates link is ok. Connectivity is through.
Check with the customer if any thing has been modified or installed.
Check if any Firewall or Proxy Server has been added or Routing table has been modified.
Disable (advice customer) and try.
Find out for any firewall or proxy present and disable. Click on Start - Run - “msconfig" – Startup
Unselect the required programs, restart the computer and try again. If starts working advice the customer for changes.

Line capacity 2016 Kbps down; 640 Kbps up
SNR Margin 10 dB; previous 10 dB
Attenuation 62.0 dB; previous 62.0 dB
If data rate is very low and Attenuation is very high above 55db, this indicates line problem. Advice the concern team to check the cable.
CBOS#sh error
If it gives repeated error messages like,
Wan0 Failed train: Init - CRC1_ERROR
Wan0 Loss of Signal Failure
Indicate poor quality of the line. Line has to be checked to avoid frequent failure of Link.
If every thing is Ok, still problem exists than connect to the router and Ping the DNS to a long interval if results show ok, this could be internal network like Cable (UTP) or lots of collision or systems may be having problem.
Can be confirmed connecting a single computer to the network.
For Slow browsing try configuring manual proxy.
Customer has to get the
domain admin username and password
from SOP and customer
can manage their account through
the website http://console.business1.net.ae/.
Customer can enter the
domain name, user name & password and access the management console. There
they can find the option to create. Modify ,delete their user accounts.
