So from the title you can see what my concern is. I have an Apple Extreme Base Station and both my MacBook and iMac connect to it. I decided to test the speeds as I always felt the iMac ran slow over the internet. I also have Fios internet. I think I have broadband turner installed on the iMac but not the Macbook. I also am connected via 802.11g. Both computers are intel core duo's. I also ran the tests on both computers from the same location in the house. Any ideas as to why the major difference? Any suggestions would be most helpful. Thanks!
