LinkSys says to call intel... is that really necessary? Fivbert

First, we should determine if it's just a lack of internet connectivity, or if it's a complete lack of a network connection.Helpful would be ipconfig info from both the VAIO, and a working PC.Open a command prompt on one of the XP machines (perferably the wireless one), and type ipconfig /all.Repeat that on the Vista PC.To copy the output to the clipboard (to paste it into your reply; or, in the case of the Vista box, to copy it into Notepad, so that you can move it to a working PC):Right-click anywhere in the command window > select all > hit <enter>. Contents are copied to the clipboard.HTH, and looking forward to your reply,Chris

Hi Fivbert, Please refer to the following Microsoft Knowledge article to check if it helps. Windows Vista cannot obtain an IP address from certain routers or from certain non-Microsoft DHCP servers http://support.microsoft.com/kb/928233 If the issue still persists, please run IPCONFIG /ALL and post the result on the forum. Thanks.
