I have a 2811 with one HWIC-1ADSL running on 12.4(11)T. The internet on this router keeps stoping. When it happens, the CD and OK leds on the router are solid green and the "show interface" command shows the interface and the line protocol up but no traffic is sent/received on the interface. The only way to get the internet up again is restarting the router. Has anyone had the same problem?
I have this problem too.
