Basic config for a Cisco 877?

I have a Cisco 877 ADSL, does anyone have a basic config I can work from to get the internet work from this Cisco 877 ADSL.

I have just added the an 837 config and change Ethernet0 to Vlan1 and it doesn't work

If you pasted the config over default, atm0 can be still shutdown. This is one thing to look for. After no shut and you check atm0, does it comes up ?

Re: Basic config for a Cisco 877?

Hi, I already had a no shutdown in there, the atm 0 goes up then down and keeps doing this. If I do debug ppp negotiate and and authenticate then I get all zeros. Am I silly to think an 837 config should work on an 877? The only difference I can see between the 2 is the 837 uses ethernet 0 and the 877 vlan 1. The 837 works fine on the same ADSL line.

You may need newer ADSL FW, either upgrade IOS to very latest T, or load the ADSL FW alone. For the latter access:

ftp://ftp.cisco.com/pub/access/800

The FW you want is 3.0.10 or 3.0.33. Check the readme for installation instructions.

Hope this helps, please rate post if it does!

As indicate in the link above, you need either to upgrade to a minimum of 12.4(6)T, or use the separate ADSL firmware.

Re: Basic config for a Cisco 877?

I installed c870-advsecurityk9-mz.124-15.T1 and the router seems so much better. The version I was using had so many serious bugs. I will add the VPN stuff next and see how it goes.

Thanks
