PS3 download speed SLOW....

[AranhaHunter]

I'm running some tests on speedmatters.org on both the PS3 and my PC, both using the same router (WRT54G V8) and this is the results I get:

PS3

Download speed: 946kbps
Upload speed: 3923kbps

PC

Download speed: 5486kbps
Upload speed: 4323kbps

The speed often varies, but the PS3 speed has never been close to 3000kbps whereas the PC speed has been over 9000kbps, the upload speed seems to be the same for both machines.

Solutions I've tried:

I have set the PS3 with a static IP and forwarded the following ports: 80, 443, 5223, 3478, 3479, 3658, 10070, 10080.
I have tried enabling DMZ to the the static IP that I set for the PS3
I have tried changing the Transmission rate on the Advanced Wireless setting from Auto to 9Mbps and 6Mbps, nothing has provided satisfactory results, does anyone have any suggestions or are facing similar problems? The most curious thing is that the download speed is so different while the upload speed is very similar.
