Hi.
I am new to the Cisco 837, and trying to set it up to connect with BT ADSL.
Has anyone tried this before? What do I need to do to get it working? I tried everything I can so far, but no luck :-(
David.

Hi Leon.
Thanks, as I am new to this router, how do i enter the values?
Through SDM, CWRS or console?
David.

Hello David,
You can by using the console. Paste your configuration after the "Router(config)#" prompt.
Router>enable
Router#configure terminal
Router(config)#
Alternatevely you can setup your router throug SDM, using the information provided by BT and the accompanied document in my previous post.
Good luck!

Hi.
I have already been trying via sdm, but i always get the same results "page not found".
I have just tried your config file with some adjustments for my details, but I saw that fail for 2 lines:
dsl operating-mode etsi
this line failed with a arrow pointing to the e of etsi
and
ppp pap sent-username myUsername@btbroadband.com password myPassword
this failed with an arrow pointing to the p of password, or in my case the first char of my pwd.
of course I change the line above to my adsl uid and pwds.

Hi.
Do I type that list of settings in somewhere? Or import them?
David.

Hello David,
The config below will work with BT Broadband.
All you will need to do is ensure that you
change the DNS server addresses and use the correct ppp username and
password.
There is no documentation regarding
assistance with configuration guidelines to PPPoA in the UK.

Thanks for that, however it still does not work.
The CD light is on, but when I try to browse the web it says page cannot be found etc.
Do you know how I can clear the code/settings from memory? The could that I copy into configure terminal etc.
David.

ahhhh, not sure why, but i can no longer access the router via sdm. Cannot find the ip address???
erm.....help
06-21-2006 09:36 PM
David,
Do the following:
Connect to the router using console.
Router>enable
Router#erase startup-config
Router#reload
The startup-config has been removed from NVRAM. Now paste the previous posted configuration into the router.
To access the SDM type the IP address used in the configuration. Check to see if your PC has an IP address assigned to it that matches the IP subnet configured on the router.
Good luck!

Hi.
I have followed your instructions, erased the startup, load on yoru last config after changing DNS and chap uid and pwd. However this has not worked.
- On the console it now prompts me for as uid and pwd that I dont know, and now cannot access the console.
- when i try to renew and check my ip address, i get a message saying that the router could not find the DNS server.
When I ran your script, I noticed that there were some other usernames and passwords. But also noticed some errors, see as follows:
gateway(config)#ip domain name
% Invalid input detected at '^' marker.
pointing to the d of domainname
gateway(config)#ip ssh break-string
^
% Invalid input detected at '^' marker.
pointing to the B of break-string
gateway(config-line)#login local
% Invalid input detected at '^' marker.
could not see what this was pointing to?
gateway(config-line)#transport preferred all
^
% Invalid input detected at '^' marker.
pointing to the a of all
I also noticed other usernames and passwords, but not sure if i should have changed those.
Any ideas?
06-21-2006 10:45 PM
Hi.
Think I just fixed the uid and pwd problem, by using the "confreg 0x2142" idea found on the www. Its got me back in, but not a clue if it messed anything else up, as I dont have a clue ;-)
Really worried why I cannot get this router to work, but DSL-504T made it so easy ;-)
is there a why I can see if certain bits have worked, so can I check if the router actually connected with ADSL? I am wondering where the problem actually is.
David.
06-21-2006 11:31 PM
Futher to my last I have just foudn that I get the following after running your script:
Windows IP Configuration
An error occurred while renewing interface Local Area Connection 2 : unable to c
ontact your DHCP server. Request has timed out.
No operation can be performed on Local Area Connection 3 while it has its media
disconnected.
Also I can no long connect to the unti via SDM, but then again, I sont know what IP addderss its using now?
David.
06-22-2006 12:51 AM
David,
Look at your router is the interface that connects your PC lit?
When connected to the console issue the command "sh ip interface brief", look at the port connected to your PC. Is both the line protocol as the link status "UP"?
Check the status of the DHCP server, as configured. Issue the command "sh ip dhcp server statistics".
When your LAN interface is up once again, and you have an address assigned you can enter SDM via the IP address 192.168.0.1.

Hi.
thanks once again.
problem is that when i run your config, I cannot login to the router, so cannot run your suggestions.
Do you know what username and password is required after the config is installed?
