Bonded ADSL Issue - 2811

Hi All

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.

Any Ideas?




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?)

Can you provide the exact error message that you are getting while trying to access the internet which will help us in resolving the issue in a better way.You can check for any issues with cable connections and also the configuration done.

Re: Bonded ADSL Issue - 2811

Hi There

As the system is remote from me and I'm unable to connect for any length of time prior to reboot - I'm afraid I haven't seen any errors.

From my end - it simply stops responding to pings intermittently (or rather it only responds to pings intermittently) and I have to repeatidly keep trying to telnet into the system until I'm, eventualy, able too - Then I reload and everything comes up fine again.

Does that help?
