Vista wireless networking pains. Need help!

[TSC17]

I have literally spent all day researching forums, posts, blogs, and tech sheets trying to figure this out.

I have an HP dv9925nr notebook. Vista 64. Broadcom 4321AG adapter. SMCwgbr-14-N wireless router.

My XP laptop works fine in wireless mode.

My HP/Vista laptop just got back from surgery, was working in wireless mode on this connection before, but after a system restore it is not. When I first got it a year and a half ago I remember going through many pains to get this problem figured out, but now I can't remember what I did to fix it!

When I connect, I can't get onto more than a couple of websites before it stops working (although it still says that it's connected to the router).

I can connect it in wired mode to the router with no problems.

I verified that I have the latest driver for the wireless adapter.

I have all the latest updates from Windows.

Any suggestions that doesn't include buying Windows 7?

Thanks in advance.
Todd

Uninstall wireless adapter and then re-install in computer management. If it works fine. If it has trouble staying connected then the adapter is struggling to work properly, and will require a new one.
