Troubleshooting a Linksys wireless router

[SLLAB02]

My desktop is connected via ethernet cable to a Linksys wireless router. (There's another comp in the house with wireless access) Around once a day, my connection fails but the other comp seems to be working fine. When I unplug the power supply from the router and plug it back in, it works fine (for about a day)

I had this problem earlier and was told to download a firmware update from Linksys' website. I just did that and the problem still persists.

It's a Linksys Wireless-B Broadband router. Any tips?

are you sure is the router and not the modem? when you lose connection is the light on on the modem?

When this problem is going on, the modem's "send" light isn't lit. I try to restart the modem, but that alone has no effect. When I restart the router, I'm back online (again, for about a day)
