Thanks guys.......changed the channel to 8 (it was on 11 originally). There is no other firmware update for the router and the drivers I have are currently the best match, according to windows. There are 6 or 7 other wireless routers in my area so maybe they have been causing the disconnection as well, although I don't have any of them in my preferred network list. Don't think it's the microwave because I get disconnected even if it's not on. Hopefully changing the channel helps. I'll see if I can find the pcmcia card that came with the router and see if it stays connected. Thanks again.
