Hi, i need some help please. I have 2 desktops and one notebook. Initially, my home network included only a desktop (windows xp) directly connected to my router, and a notebook (windows vista) wirelessly connected to my router. Today, i tried to connect (directly, with a cable) my other desktop (windows 7). Although this shouldn't happen, i get no internet connection on it. The network is detected obviously, but with no internet, which is strange. Additional info: - My router is a WRT54GS, by Linksys - My PC with Windows 7 used to be previously connected to another network: a switch that shares the internet connection with my neighbours in my other apartment. There it works with no problem at all. Thank you in advice for your help, and if you need any more info, just ask me.
