I have cable internet, my home network consist of 2 desktops hardwired to the router and a laptop connecting wirelessly. I ran the setup cd from desktop 1, and everything set up fine at first, all 3 computers worked. Later desktop 1 quit working, it will connect to the other pc'ss over the LAN, but not the internet. I have changed every setting I can think of, and then reset to factory settings, nothing works. Any ideas?
