7057 x64 Broadcom wireless issues

After my kid went to some less-than-savory websites, my PC at home was infested with a slew of viruses.

I figured it was time to install 7057 since I had such good luck with 7000 on my netbook.

I installed and everything appeared to be fine, but then, using the Microsoft provided Broadcom 802.11g wireless driver (just as it is labeled in Vista Ultimate, which works PERFECTLY), things started to act flakey with my internet connection.

It's a Belkin branded Broadcom card, but I have never had issues with it. After switching back to Vista it's working perfectly again.

I ran Windows updates, then started to surf the web a little to find some drivers and in the middle of doing nothing out of the ordinary, internet connectivity simply dropped.

It showed me still connected, but only for local access - no internet.

I rebooted - couldn't even connect to the wireless now.

I did a cold boot - connects but local only.

No other PC in the house was having any issues.

I've tried it using DHCP and a static IP - both of which worked on all other machines as well. No joy.

The router I am using is the first generation Belkin Pre-N, which for the past year has needed the occasional reboot, but didn't really have any serious issues.It is several years old.

As I said - no other machines had any problems. They are all running Vista Ultimate (a mix of x32 and x64), along with my netbook running x32 build 7000.

So, can I suspect that there is an issue with the Broadcom driver? Or maybe that the Router is too old to handle something that this new build is trying to do? Is anyone else having similar issues?

I'm going to be getting a new router, simply due to an electronics refresh that I am doing throughout the house, but, I don't want to have to futz with the desktop machine anymore on Win7 if I am going to continue having these issues.

Thanks in advance!
