I have a 2811 with 2 ADSL cards that are bundled using MLLP. Problem is the internet connection frequently (every couple of days) seems to slow right down almost to nothing, I get intermittent connection to the internet and struggle to telnet remotely onto the router - however if I keep trying, eventually I get onto the router (remotely) and perform a reload - then everything returns to normal speed.
I enclose a copy of a show ver - because i seem to recall hearing that there was bug that caused this (but I could be making that up?)
