All was fine w/ connecting to a linksys wireless router to my Windows XP Home computer, until it stopped working. Usually a reboot works, but not this time. I need a fix-it solution. Signal strength is "very good", I refresh the available networks and click "limited or no conductivity" and the pop-up window says: "This problem occurred because the netowrk did not assign a network address to the computer" When I click "details" there are values for Physical address, IP address, and subnet mask. The router is set for dynamic addresses. All other computers are XP and use the same wireless router. They are connecting fine. Any help is appreciated.

The first question that comes to mind, because you do not state this, what computer controls your Wireless Router?

A home network router usually has at least one PC directly connected via a LAN cable, from the Network Card on the system. At work, our local Server is directly connected to our ISP's router.

You also do not specifically state if the PC in question is also on wireless, but your reference to "signal strength" implies wireless.

Having said that, your problem looks like the PC in question is not setup for Obtain an IP address automatically AND Obtain DNS server address automatically.

Your DNS server is your Router.

You may want to contact your ISP for specific help with your router, since the specify what is needed at your end.

Then, your wireless "card" MAY have gone South

actually Teknomage, the subject of the thread states wireless

Some good suggestions though, especially checking that the wireless adaptor isn't set to manual settings at the moment.

There are other reasons that the wireless network adaptor may not be working correctly, but first I'd verify that a cable connection works to the router. Should be quick and easy to test that since most laptops have both wireless and network adaptors these days
