I have a speedstream DSL modem from SBC that is connected to my Linksys 54G Wireless Router. I have 2 PC with 54g wireless cards and a laptop with a wireless notebook card that are connecting to router for inernet. After I have configured the router I get all my computers on the network and connected to internet. It works for about a day and then I lose intenet connection on all computers. I still have connection to router but cannot see other PC's on network or get on internet. I have tried upgrading firmware and that didnt help I also am broadcasting my SSID. When I lose internet connection I take my Linksys router disk and walk through the steps to reconfigure router - I am then able to get on to internet for 24 hours or so then I get the same issues. I am able to get on to internet by pluging laptop directly into DSl Modem so i know there is no issue with modem - i cannot however plug into internet on one of the ports on back of router. Any info would be helpful at this point !!!!!
