Hi all, I have a problem that is driving me crazy! My ISP is Mediacom (I do NOT recommend them), and I use a cable modem (RCA) straight into my iMac, 24" 2.4GHz, late 2007 Al, running 10.5.6 and Safari 3.2.1. According to my iStat pro widget, my network in fluctuates between 1kb/s and 5.2Mb/s. Mostly the slow speed. Mediacom is sending someone out on Monday. Is there anything I can check or do in the meantime. The iMac is the only computer around here, and I've rebooted the cable modem until I'm sick of it. Even rebooted the iMac. I used to think TW was bad until I had to use Mediacom. I think Charter is now in this area, I may try them.
