So, my house has Wifi that works pretty consistently with all of our computers, both macs and PC's. However, we just set up our iMac (which runs Snow Leopard) for the first time in a few months, and data just trickles in. It usually connects to the router, but if a page loads at all it will take at least a minute (which is obviously entirely useless). I've tried playing around with AirPort settings a little bit, but nothing has worked. I've also done a good deal of internet searching, but nothing particularly helpful has arisen. So, does anyone have any possible suggestions?
I should also mention that I brought it to the Genius Bar to have this dealt with. When I was there, however, the store internet worked fine. This was after the employee showed me how to clear the PRAM, so we figured that this was the issue and I left on my merry way. However, the problem was the same back at home, no matter how many times I reset the PRAM.
