    Here's the basic problem: wired network works fine, but no wifi will work at all while the new Windows Server 2008 is running. If the server is shut down, wifi works great. Server is AD DC and DNS server but is not serving DHCP. Tried with 3 different wireless routers (Belkin, Linksys, Netgear) and 1 WAP (Intellinet). Routers were tried in routing and bridge mode. DNS server setup is pretty simple with just 2 forwarders to Comcast DNS servers. Wired configuration is: all workstations and server hard-wired to switch, switch goes to Comcast router. Ever seen anything like this? Any ideas would be greatly appreciated. -Chris

    Sounds like a misconfiguration on the router part. Can you give more details like ipconfig /all from server and the network configuration of the router?

    You could also try Microsoft network monitor on one of the wireless clients and run a capture when the server connects to the network and wireless connectivity goes down.

    Also just to be clear, do the clients appear connected to the WLAN but no internet access is available or do they just disconnect from the wireless.

    If you configure a wireless client with a static ip address does the issue still occur?

    If the router was configured improperly, I would expect a problem with the wired network as well as the wireless network.

    Server ipconfig: IP: 10.1.10.50, sub: 255.255.255.0, gate: 10.1.10.1, dns: self, set as loopback 127.0.0.1 in adapter.

    Wireless clients connect great, and they immediately lose connection when the server boots. No connection at all, and it is not possible to re-connect them while the server is on.

    Configuring with static IPs does not resolve the problem.

    I will try the MS net monitor and see what comes of it.

    Thanks so much for the ideas!

    Hi,

    Thank you for the post.

    You may check the ip configuration on wireless client, if the wireless client lost connection, you should also check the config on the router.
