Hello, I have a late 2006 G5 iMac with isight, and I have been experiencing some issues with my "high speed" internet. The iMac was in the shop for a while getting a new hard drive, and when I got it back, my internet was blazing fast. That lasted about a day and a half. Slowly the speed died down, from 1mb+ per second, to about 160kb per second. What is going on? I've had to deal with the slow internet speed for a while (also long before the computer was fixed), but I had never taken action, other than replacing my modem and router. I have a PC in the house connected though ethernet, so I know its not my airport. Any help? Thanks.
