Hmm.. Yes, this would be one common factor for sure.... Strange that we have hundreds of Comtrends in production though - possibly a firmware issue though...
c7200-ik9o3s-mz.124-13b.bin here.... I think we may swap a few of these client modems and see if there's some common ground. So far I haven't heard anything back from the list suggesting this is a Cisco IOS/router issue...

We're generally using Comtrend 5621 or 536+, but we have a lot of Draytek in the field, too. We using c7200-is-mz.122-26.bin, what's yours? Since only one customer has called and complained, and that appeared to be fixed by putting in a Westell (after much urging from the customer), I've just put it aside, hoping that the next time we do a software upgrade it fixes itself. To put the Westell 'fix' in context, here's some counts of their login (from radius log). 8 Apr 1 9 Apr 2 13 Apr 3 9 Apr 4 7 Apr 5 12 Apr 6 13 Apr 7 12 Apr 8 12 Apr 9 16 Apr 10 10 Apr 11 13 Apr 12 8 Apr 13 11 Apr 14 13 Apr 15 12 Apr 16 13 Apr 17 11 Apr 18 5 Apr 19 1 Apr 24 1 May 21 1 May 22 1 Jun 30 3 Aug 5 My only guess is that the DSL modem (because normally we deploy PPPoA, only configuring the DSL modem as a bridge and PPPoE on CPE when customer needs it for their own equipment) is somehow breaking the session.

This is a long shot but we have some clients who are connected via PPPOE on ADSL2+ who are randomly dropping off once in a while. On the same ADSL2+ system, we have a number of clients who are online for weeks with no issues. Same equipment, identical modems at CPE etc.... they are all Comtrend CT-5071 modems connected back to our Occam DSLAM.... The router config there (7206VXR) is identical to other locations (dozens of other locations).... so I can't see where this could be a Cisco related issue but reaching for ideas... the general feedback is that most of them stay online for 10-15 minutes and then their PPPOE session drops. Their line sync on the physical side looks VERY clean and no loss of line sync or retrains...
