Hi, I've recently had problems with my mid 2011 27" iMac wifi cutting out. Trying to upload/download documents is a huge hassle unless I hardwire a connection (which is not convenient in my apartment set up). I've also noticed my bluetooth mouse cutting out just as often, even with fresh batteries. Oddly, keyboard doesn't seem to have the same issue. I'm mostly concerned about the wifi. Any suggestions? I tried the SMC reset process, updating OS X software, etc. Nothing seems to work yet. Prefer to avoid lugging this "television" to the Apple Store for support if at all possible.
