Cliffnotes: Windows Update may cause sluggish WIFI. Theory, likely a driver incompatability.
Just got a iMac 21.5 inch last week, my Model Identifier is 13,1 for late 2012 model. Installed Windows 7 Ultimate to bootcamp, worked great initially. But after running Windows Update overnight, the Internet became super slow. Don't know if you youngters remember those days of 56k modems, but my WIFI speed was exactly like that.
I isolated the slow WIFI to Windows 7, since it worked perfectly in Mac OS X.
Troubleshooting steps:
- re-installed bootcamp drivers for windows
- researched apple.com and macrumors.com forums. if you google "slow wifi bootcamp" you'll see it's a prevalent issue and nobody seems to have found the cause
Solution: Reinstall
Couldn't find a resolution so... I uninstalled the Windows 7 product key ("slmgr.vbs /upk" at command prompt) then deleted Bootcamp from within Mac OS. Then I reinstalled Windows 7 without Windows Update and now everything is fast again.
So, it has to be some kind of driver incompatability. Guess I'll carefully have to run my updates sections at a time until I isolate which one not to touch.
