Intel 4965AGN and Intel 3945ABG adapters in div. Laptops hanging apps, dropping out.

Im so tired of these Intel Wireless adapters in laptops from Dell and Lenovo ThinkPads.

So many angry users and customers having troubles with the laptops I have installed for them. Some of the pc are experiencing a lot of wireless disconnects and everything is "hanging" on the Windows XP for minutes and then it comes back to normal. In these minutes the pc is extremely slow on every mouseclick and every keyboard stroke. I don't know what is really happening.

I use the newest drivers from Intel. And I allways uninstall the Intel Pro/Wireless software and let Windows XP handle the wireless connection.

But maybe thats my problem. Have any of you guys any experience regarding Intel Pro/Wireless software? Or should I NOT use the drivers downloaded from Intel, and instead use the drivers from Dell or Lenovo/IBM

ANy comments are welcome

I've worked on a lot of HP laptops and Asus laptops, which come with the intel wireless adaptors as standard. They seem to work fine for me. One thing to check is to make sure that you have the latest BIOS installed on the computer, and that the PCI bridge is working correctly. Otherwise, just hassle Dell about it (personally, i've had so many problems with Dell, i don't bother with them anymore.)
   Is it a new install it's happening on? If not, try booting from a Linux CD, seeing whether you get the same mouse-click problems as before. If so, then it's hardware. If not, try reinstalling windows, or at the very least, updating. Download all the latest stuff from Dell as well, as they sometimes have 3rd party wireless managers.

One of the users works great wireless at home, but on the office he gets trouble. On the Office they have a linksys N accesspoint. But other users with same ThinkPad T61, same Intel driver version have no troubles.

We have the same problems with getting disconnected at a major university.  I really think that this is an incompatibility between network cards and our access points (Proxim AP4000).  We ran a trial with Cisco Aironet 1200 access points and had no problems.  Check out the below article and see if this helps you.
