I have the Linksys WRT54G router with 3 computers connected wirelessly. 2 of the computers are desktops and use the WMP54G adapters and 1 is a notebook that uses the WPC54G adapter. All the computers are running Windows XP and have just been updated with XP sp2. I also have the wireless camera WVC11B and the EFG80 Network attached storage which is connected to the router via ethernet. My problem is that several times a day I lose the network signal and usually, within a couple of minutes, the signal returns on its own. I use the windows wireless zero configuration to connect to the router. When one computer loses the signal then all of them lose it and they all reconnect at the same time so I think it must be something with the router otherwise I would think that only one computer would lose the signal. The camera also disconnects at the same time. I have all the latest firmware and driver updates. This has been going on for over a year and every time a new firmware release comes out I think it will fix the problem but so far they haven't. I have run NetStumbler and I have a very strong signal on all the computers. I have to run the router in mixed mode because of the camera being wireless-b. I use 128 bit wep encryption, I have the ssid turned on, and I use mac filtering. If anyone has any ideas on what the problem could be, I would be forever grateful!!!! Thanks for your time.
