My ISP connection is 30 meg down and 5 up. My PlayStation 3 is hardwired with cat5e. All of the PlayStation Network ports are configured and forwarded on my router.
The test: Go to speakeasy with PS3 and perform test with Seattle. This is the best glass backbone to Montana. I am lucky if I get 4 meg download speed, the up speed is decent. Second test, unplug PlayStation 3 and plug in MacBook Pro. The results are that I can utilize the full bandwidth of my service from the same patch cable, wire through house and port on router. 30 down and 4.8 up.
I also removed ubuiti router and replaced with a pos netgear. Test results did not vary and router firmwares were up to date. Any ideas?
