A couple of days ago I began to notoce it was taking a long time for pages to load. In my mind, I just blamed Comcast. Today it was getting bad, but my wife's Mini was loading pages fine. So I plugged an ethernet cable into my iMac and pages were loading immediately. Looks like there was a wireless slowdown. A reboot has brought 90% of my speed back, but still not where it was before. So why would one computer (iMac) experience a slowdown and not the other (Mini). I really had never used wireless as my main connection before I got a Mac and an Extreme, but they seemed to work so well, I never connected the cable. Seems like I may have to. Is this normal?
