Built-in wireless Service Pack 2 DHCP

By chris.rodgers ·
I have some new Toshiba and HP laptops with built-in wireless Nic's (A,B&G). Since putting on Service Pack 2 none of them work. My set up is #com access points with WEP enabled at 128 bits. The clients connect to the AP's but it is never able to get a DHCP address. I've tried hardcoding it and that doesn't work. Anyone have the same issue or resolved it?

Welcome to the world of sp2. Sp2 has been known to cause more than a few issues when updating a pc.

Let's start with the simple stuff. The sp2 installed new drivers and updates for wireless networking. These updates prefer wpa (if supported) over wep. Check your ap configuration and see if it supports wpa. There should be a wpa key field in the wireless configuration screen. If so, copy down the key. Then go to the pc and use the ms wireless configuration (not the manufacturer's configuration utility). Enter the wap key in, save and reboot. You might need to uninstall the manufacturer's driver's and remove the current wireless card from the hardware configuration. Let windows re-detect the card and use xp's drivers to make this work. If it works then do the same for all other problem pc's.

Also check the Microsoft firewall which got installed and activated by default when you installed SP2. It is possible you have a port blocked which you could need to get the IP. Just turn it off temporarily for testing purposes, reboot and see if your wlan cards now get an IP. If that is the case configure the firewall accordingly, or if have a 3rd party firewall anyway, leave the M$ version off and use the 3rd party product. Be sure to apply patches to those 3rd party products, supplied from their homepage, as they often have some issues with SP2 as well.
