Hi, have just got myself a mid 2012 MacBook Air 13 inch and have just installed Windows 7 using Boot Camp. However, the WiFi signal was very poor on Windows 7 when I first installed it even with the latest Boot Camp support software from Apple. The WiFi works just fine on my Mac OS X. Googled around and managed to find a partial solution (https://discussions.apple.com/thread/2709273?start=0&tstart=0), which is to set the "Minimum Power Consumption" in the driver settings in Control Panel to "Disabled". This has made the wifi signal strong with 4/5 bars for the first 5 seconds, and then it will drop to 1/2 bars for no reason. Broadcom wireless drivers are also updated to the latest, at least that's what it says when I tried to update it from Device Manager. Any ideas please? Would really appreciate any input. Thank you!
