Microsoft Notebook Adapter MN-520 known capatibility issue msg

I have an HP laptop with a Microsoft Broadband Networking Wireless Notebook Adapter MN-520 and I repeatedly get the following message "Microsoft Broadband Networking has a known compatibility issue with this version of Windows. For an update that is compatible with this version of Windows, contact Microsoft Broadband Networking" and I keep losing my connection to the network. I use a linksys wireless access point/router. The Linksys WAP works fine with my 3 other PCs using other makes of wireless cards.

    Only the HP and my Dell are running XP. One machine is a new Toshiba laptop using a built in wireless card and Vista, one is a desktop with a PCI wireless card using Win2000, and the last is a Dell laptop using a built in wireless card on XP. I think both XP machines are on the same service pack since I go to the Windows update site all the time to make sure they're up to date. The HP machine used to work fine but lately it's been losing it's network connection frequently. My daughter was using it at school without a problem, but over the last couple weeks or so it's gotten bad.

    And I am guesing that the other three computers have a different version or service pack that the last one?

For troubleshooting purposes, ensure that the problem PC and the access point are on same line of sight and try to observe your connection.

1. Go to control panel and click network connections
2. Right-click wireless network connection and click properties
3. Go to authentication tab and ensure that IEEE 802.1x is unchecked
4. Click Ok all the way out

Also, check whether the problem occurs when connecting to other wireless access point. You may try changing wireless channel on the access point.

MSBN MN520 not linking to linksys wireless g rtr

You also need to enter a WEP encryption passcode if you have done so on the router. Best to check the wireless settings of the router first. Both router and wireless adaptor must match exactly.

Blue screen display

Check the memory of your computer. this could cause blue screen display. Be sure to check also the cooling fan for microprocessor and video card cooling fan if it is working. Sometimes it cause blue screen and needs to re-start your computer. If you have two slot of mem that is occupied then, you can remove one and leave the other one. Be sure to power off your computer before doing this. Then turn on your computer and try to observe it. If the problem still exist then do the same with the other memory and check it again. I hope that these could help your problem.
