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?

Though most of that question and answers came down to plugging in your PS3, which you have done. –  Jason Berkan Feb 8 '12 at 21:05

Have you tried plugging your PS3 directly into your modem and bypassing the router, just to eliminate the router as an issue? –  Ben Feb 8 '12 at 21:21

Yes, I have tried patching straight to modem. I would guess that if it were an equipment issue on the network side, my Macs or PCs would also see the issue. Thanks. –  Montana Feb 8 '12 at 21:55

Did you try the PS3's own network test instead of speakeasy? –  Ben Brocka Mar 8 '12 at 15:49

Here's the thing about data transfer and the device it's connected to. While I suggest you keep looking for a fix, the main thing about Bandwidth utilization is that even if a great quantity of data is being sent to your PS3 by your router, it's dedicated network processor can only process so much data, and Sony limits this to save on procedural resources to the highest necessary speed.

The PS3 uses a CELL processor setup with several modular CPUs, but just 256 MB of ram, so its ability to receive and process incoming data is quite limited.

I would still suggest you stick with the wired connection to limit latency.
