Hi all. I've searched quite a bit without finding resolution to this one. I have a wireless router installed at the house with three laptops currently able to connect to it with no problem. Two are running XP, one is running Vista. I have a fourth machine, an XP desktop, in the basement with no wireless card and located too far from the router to run an ethernet cable. For logistical reasons outside the scope of this post, the Vista laptop is the only one I am able to bring into the basement to try and share an internet connection with the desktop. I have an ethernet cable connected between the Vista laptop and XP desktop, with file and connection sharing enabled, password protection turned off and Windows firewall disabled on both machines. Each of the two is able to recognize the other and access shared folders on the opposite machine without incident. The XP desktop however does not recognize an internet connection. The status of the LAN connection on the XP machine is detailed as "Limited or No Connectivity" due to "the network did not assign a network address to the computer." Clearly the connection itself or broadband adapter is not at fault since the desktop can communicate with the laptop. It's just not reaching past the Vista laptop to the internet for some reason. Running ipconfig reveals in fact the ip address to be a Windows internal address, 169.254.xxx.xxx. The last time the desktop was hardwired to a router, it accessed the internet no problem. Any ideas on how to go about fixing this?
