I have a small network which I use on the road. Ideally I want have one computer as an internet host, using a Cingular broadband card. The other computers are hooked up through a router and network cable. I've had success with this setup working, by sharing the wireless internet connection on the host computer, and setting the other computers to obtain an IP address automatically. While this works initially, I often have to unhook my laptop from the network and then hook back up. When this happens, I get "limited or no connectivity" on the network. Can anyone help me out so that I can always hook up and have it work?
