Hi all,

About two weeks ago, my WRT54GL (v.2) running 7.06 started randomly rebooting every few hours/minutes and I'm stumped as to why. Can anyone give any advice on why this might be happening? During some points in the day, it reboots every 10 minutes with little network load. I haven't changed anything on the router and it was working quite fine up until last week. It is connected to a UPS and the line voltage is fine.

I have a quick-and-dirty script running every 5 minutes gives the router stats but there is nothing indicating why it reboots.
