Lenovo Thinkpad Laptops Failing to Connect to Wifi

I ran into a recent problem where a Windows 7 Thinkpad would not connect to wifi access points properly. It would connect to the Thinkvantage wifi profile, but networking was unavailable. Wired access worked fine, as did everything else. The problem ended up being the Thinkvantage tools.The advanced wifi settings of the network profile showed a power savings setting of maximum savings. Switching that to medium savings enabled networking. I suspect the laptop would have worked if the WAP was only a few feet away, but this user was over 30 feet away.
