I am having problems connecting over ADSL using an 857W router in the UK. My provider is Demon. Is anyone else having problems?
Config used is below,
interface ATM0
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
ip route-cache flow
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM0.2 point-to-point

What kind of problem do you have?
Do you have a link (CD led on)
If so, verify the vp/vc setting with the ISP and issue the "debug ppp neg" command to check for possible negotiation issues.

I changed the ATM interface from dsl operating-mode 'auto' with ansi-dmt as suggested.This seemed to improve connectivity as the CO led remained solid for 30s before dropping off.
debug logs below. Dialer debugs look most promising
Thanks for your help.

Hello,
try and configure ´ip mtu 1452´ on your Dialer1 interface.
Also, configure the following on your Dialer1 interface:
ppp authentication chap pap callin
ppp chap hostname USERNAME
ppp chap password 0 PASSWORD
ppp pap sent-username USERNAME password PASSWORD
If that doesn´t help, can you post the full configuration of your router ?

Nethelper
