I have to say that though I hear other people speak of their
routers needing frequent rebooting, I've never had such a problem,
though I have to admit that I've only ever owned two routers.
The first of th em was a WRT54GL, and it ran fine. It would run
for months, and only get rebooted after a power failure, or when
changing things in its UI that required it reboot. I ran the factory
firmware for a year or two then switched over to DD-WRT, and again
never saw that kind of problem.
Just wondering if you've ever done a firmware update? sometimes
even the manufacturer will issue a bug fix firmware update, shocking
as that may seem! :)
After five or six years, it suddenly decided it didn't want to retain
any of my settings across a reboot, and it was a huge pain to reset
all the settings I had made, without notice, whenever it decided to
drop them all. So I bought an ASUS RT-N16 and put the Linksys aside
for a while.
Subsequently, someone else I knew needed a router for guest network
access, and I fired up the WRT54GL and reinstalled latest Linksys
firmware and it has been running fine ever since (couple of years,
more or less).
Wish I could offer some actual help! :)
