[c-nsp] atm0 going down every five minutes (DSL: Defect: LOS LOF LCDi: retraining)

[Elmar Pigeaud]

Sorry to re-submit the question, however, I got somewhat further. Our c836
router loses connection every five minutes. The line is ok, other modems
work fine. Our provider can see no problem. Can this have something to do
with my config? At the moment it is still very simple, and I have never
encountered a similar problem with the same provider.

Has anyone ever seen a similar problem?

Thanks in advance!
