However whilst they've all occasionally resynced (between weekly and monthly or bi-monthly), which is no problem, more or less with different modems this has taken the form of a reboot.
Just out of curiosity, what (other than a power disconnection or manual reset, which are not in issue) causes a modem to reboot rather than just resync? The only noticeable difference I can see is that the log usually just carries on with just a resync, but resets with a reboot. My current modem/router, a FritzBox 7390 running on FTTC (in place of the OR modem) shows an "error report" when the connection comes back up (but I can't access any details) on a resync with a reboot (but not on one without).
In both cases resyncs usually complete within a minute or so. Invariably I'm not using any connected apparatus when this happens, so it's not a problem.
I've a Netgear WNR 2000 running (again through a UPS) on my second fixed wireless service, which occasionally resyncs with the cable modem but has never in over 2 years rebooted (other than after a manual disconnection), so I'm assuming it must be something to do with the characteristics of DSL or the router rather than power supply per se?
EDIT: I suppose it could be the modem just decides its "had enough" and "needs a break"!
