I have Time Warner Road Runner internet service, and on my brand new Mac Pro, the speed of my internet connection is awful. I've tried connecting wirelessly to my Wi-Fi network, and it connects automatically, with no issues, and with a strong signal. However, the speed is terrible (something like a max of 20kb/sec). Safari and Firefox both are extremely slow. I have a PC in the same room as my Mac Pro connecting wirelessly, and it is extremely fast. I even ran a very long ethernet cable I happened to have all the way into this room, and the performance is still terrible. There is a PC in the same room as the router connected directly to the router, and its performance is flawless as well. I ran an online speed test, and it seems to think my speed is normal for a cable modem, which I found to be very strange. Any idea what settings (Mac, Airport, or router) or resources might help me solve this problem? Any help would be so greatly appreciated! Thanks!
