I am supposed to get DSL speeds of 3MB/s down and 756 Kb/s up. I get in the 370s to 390s Kb/s down and 70-80 Kb/s up. This is monitored via iStat on both my Mac Pro and MacBook Pro. I contacted Surewest, my DSL provider. They said I was pulling the proper speeds and to run a speed test which I did at www.speedtest.net which also showed the proper speeds. My configuration is as follows: Line from the wall into the Surewest router to a D-Link DES-1105 10/100 Ethernet Switch. From the Switch, I connect directly to my Apple Mac Pro and separately to an Apple Airport Express Wireless for my laptop. Speeds are consistent on both the Mac Pro and MacBook Pro. I tried rebooting the router, no change. I removed the switch and went directly from the router into the MacPro, no change. I also tried this with the MacBook Pro, also no change. All roads appear to lead to the Macs. Any advice on what settings I should look at to see if the Macs are indeed the problem? Thanks in advance.
