PPP/LCP problem was created by brscarl
Can anyone help with the following issue.

Setup:

Force9/PlusNET
Vigor 2820
3.3.5.2_232201
ADSL2+ Annex A

I'm seeing loss of internet access and on checking the router see that the
router is re-authenticating (not re-syncing).

I hooked up syslog and see the following:

Code:

I cant understand why there is no EchoRep coming back yet a TermReq gets an immediate TermAck or is this local ?

I had a similar bout of these symptoms about 2/3 months ago for about 2 weeks where i changed all the local hardware
but didn't get any syslog data.

Anyway any help on where the problem is likely to be much appreciated.

Many Thanks
Carl
