I have been researching for days about people having issues with their iMac's download speed. All the fixes I found really didn't do much for me. I have 4 computers in my house and I pay for download speeds up to 60Mbps. When placing all of the computers on the same desk, 3 out of the 4 computers (bot my imac) download between 45 and 58Mbps. My iMac is download at 5 to 10Mbps. Is anyone else having the same issues or know of any fixes? I know it has something to do with the wireless card since when I hard wire the iMac into the router I'm downloading at 60Mbps. Any help would be much appreciated. I'm testing on both speakeasy.net and speedtest.net.
