Hi All,
I have recently configured a cisco 887-m for a new ADSL connection.
The connection is presented as ethernet from an NTU.
The first day i put it in, it was working for 2 days then dropped. Turning the router off and on fixes the issue except twice now it has dropped again overnight. When i console in i cannot ping google.com from the router.
Here is the config
ROUTER#sh run

I don't see any line issues, however, if you say that a reboot fixes it then I'm incline to consider a potential IOS bug.
I can see you are using an IOS "T" train. I'd recommend you upgrade your IOS "M" train.

post the output to the command "sh dsl atm".
02-24-2014 05:17 PM
The atm interface is not being used as WAN connection. The connection is coming in through F0 which has switchport access to VLAN2

Make sure your DRAM and your router's flash is the right amount.
