I have three Macs (G5,G4,G3) and one PC on my network. Until last week everything ran fine, then monday all three Macs started to crawl on downloads, but the PC is fine. Thinking my cable modem was bad I got a new one, no change, went back and picked up another cable modem, still no change. I took my router out of the system and hooked up my G5 straight to the modem and still my download speeds are in the crapper.
Every speed test I run the Macs top out at 1.2 Mb, while the PC gets 5Mb. My downloads are creeping. Time Warner came out checked all my lines and everything is perfect. My up and down SNR and levels are fantastic. I have very low ping and latency. As I said the Macs have worked fast and perfect for 6 years until this past monday, and then all 3 at the same time hit the wall.
Time Warner brought a PC laptop over, hooked it to my network and it too got 5Mb down. They are washing their hands of the matter saying if the PC's work then its something wrong with the Macs.
I have turned off IPv6, tried forcing duplex and speeds, Cleared pref files, reloaded the entire OS. Even tried going all the way back to Panther, and still saw no improvement.
Equipment:
Surfboard 5101 Cable Modem
Dlink-604 Router (I can remove it, same problem)
G5 1.8Mhz single CPU
G4 800Mhz
iMac G3 500Mhz
All Run Tiger 10.4.6
Any help Ideas would really be appreciated.
Thanks
