My broadcom 802.11b/g wlan driver disappeared a week or so ago and I can not get it to reappear - so no wireless capability. I've read several older posts describing this problem but no clear solutions? If I start in Safe Mode, it is there. If I start it in Normal Mode, it isn't. MYLinksys wireless router is working fine for Bluetooth and my HP printer... Anybody who can help?

Did you install any updates at that time? Something that's starting in normal mode is conflicting with the drive loading. You can disable all under the startup tab in msconfig, reboot, click ok & see if it's there. Actually, before you do that, make sure that the wireless service starting in services. How do you know when a politician is lying? His mouth is moving.

I justattempted a system restore...which failed. And then it advised that my computer start up was broken. After asking it to fix itself, it did and the broadcom driver was present and is now working for my wireless router. So, I may have fixed it by blundering into something else?

That's a possibility. At least it's working. How do you know when a politician is lying? His mouth is moving.

A had the same problem on my HP tx1220ca laptop with broadcom wi/fi. The problem appeared on both Vista Home and Windows 7 OS. After many frustrating attempts to uninstall and reinstall of drivers, system recoverys, trouble remained. I finally decided to disable the Microsoft ISATAP Adapter and the wi/fi begins to work again! Go to Device Manager under Computer Management, open Network adapters to disable ISATAP and reboot the machine. Hope this works on your machine...
