Alienware M17 R3 (windows 7) has no wireless anymore. Is Bigfoot Network Killer to blame?

[berbes]

Hello. I have a Alienware M17 R3 (windows 7) that has no wireless anymore. There were a few other problems, so I figured the easiest fix was to install Win10. Everything but the AMD drivers worked (and Googling that showed alot of folks with this machine had the same Win10 video probs), so I put back the old HD and looked around, but cannot find anything that shows the wireless drivers. The ethernet works fine, but NO wireless whatsoever. They have Bigfoot Network Killer installed. Is it to blame? Should I uninstall that to bring back the wireless?

Thanks for the ideas!!
