Linksys wireless router Troubleshooting

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?

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

might be a problematic ethernet connector on your mobo you can buy pci ethernet cards cheap enough , i use linksys router without a problem & love it
