Hi,

It might not be with the Wireless zero config, that is a service that has to be started if at all you need to use wireless, Both Win 2k and Xp have that service, the problem i feel is with the wireless , you don't need to restart the machine after the you are disconnected, just click on view available wireless networks in the task bar and select the SSID and click ok, Also if you have WEP then enter the WEP key, and it should connect,

also don't use cahnnel nos like 6, they might cause interference with the normal telephone lines, use some thing like 9 or 11,

Hope this helps.

MRG.
