Specs: PS3
I Have Comcast 20/3 docsis3 service South FL.. Upgraded from DOCSIS 2 Linksys modem/router (WCG200) to SB6120 DOCSIS 3 modem & gaming router. Before upgrade PS3's speed checker says ~3MB+ upload speed. After upgrade 1Hr later: (Forget Router: connected directly to SB6120)....Upload speed 760K average. (Download much faster, but this is about upload.) PS3 WIRED, no wireless. Modem has blue download light, but green upload light. Called Comcast again & got the "we don't support gaming" crap. PC's on Speakeasy got 19.5 up and 3.69 down to NY. I think we checked Speakeasy on the PS3 browser and got numbers comparable with the PC's. Wife is NOT happy. Anyone know what's going on here. She shoots players first and gets killed. Thats why we bought the new modem! Please help! My ears are ringing from the yelling...

So, no router + no wireless = no reply?

The problems were the following: The coax connections from the street were poor, and the Comcast tech came and replaced the connectors outside the house. We also moved the modem closer to the cable entry into the house, which eliminated some more splices in the attic, .

We also determined that Comcast did not have the correct MAC address for the new modem, so it wasn't working right; maybe a typo when I called the new one in. After several calls to Comcast to verify the MAC address, and plan we were paying for, the issues were resolved.
