I have att u-verse guaranteed 18 mbps. My PC desktop is hardwired and getting 21mbps. My iMac uses the Wifi and im getting around 4.5 mbps. The internect for my mac comes and goes alot. Sometimes I cant even load a page for a few minutes and the loading bar will not move in the url. I dont have alot of apps running. I deleted my internet cache and that increased it by about 1 mbps. Any ideas guys? Thanks so much
