For the past couple of weeks, I've been getting dumped from my NAT/PPPoE connection at least a couple of times a day. The same configuration has worked flawlessly for about 3 years, so I was starting to suspect SBC was dumping me. I use a SonicWall firewall with NAT/PPPoE and a SpeedStream 5360. Still digging into the problem. Another interesting issue is that the SonicWall tries to reconnect automatically, but I have to completely recycle the modem before I can get reconnected. I even tried my old 5260 modem with the same result. I don't see any glaring issues looking in the SonicWall log file.

Any thoughts on this one?

You've had DSL for 3 years....have you had the Modem that long too? If so, possible the modem is going bad. Other than that...not sure. Is your modem near anything that could cause electrical interference( the usual tier1 stuff).

Try it straight without the router, if it does the same thing, then it might be wiring problem or a problem in the Central Office. Basically, sounds like ASI may need to get involved to check things out. If the connection stays solid without the router, then you might've found the problem.

It's happened again several times in the last hour or so. I'm collecting information via my SonicWall log file. I've watched the modem lose it a couple of times, but the router always reconnects. I did have to recycle the router once because it couldn't re-establish a PPPoE connection. I'm not suspecting the SonicWall is the problem at this point, but I'll collect some more information, and if that proves useless, I'll bypass the router, and see if the problem goes away.
I won't be able to live without printer for more than a day, though, and it's only connected via the network. I'll have to reconfigure IP's to test connection without router, so I'm considering that a last resort.
I'll attach my sonicwall log as it stands right now, for amusement. If the times can be checked against network information at ASI, maybe a correlation can be made.

UPDATE: As of this morning, my PPPoE connection was lost 7 times in the last 8 hours. Updated log file attached. Increase in frequency in the early hours of this morning.
Now THAT's what I call a dynamic IP address!
