I am running a Power Mac dual 2.0 processor with OSX Tiger (10.4.3) with an ADSL modem. My download average is about 1 mbps and upload is averaging about 415 kbps. My isp says I have 1.5 down and 512k up Max. I can live with 415 up but would like to get my download speed up to about 1.3 mbps. Sometimes, I can get 1.25 mbps download but would like to get my (average...1 mbps) upload average to about 1.3 mbps down. Anybody else out there using Mac computer running tiger? Any suggestions would be greatly appreciated!!
