COD 5 problem on PS3

The online play has been working great for COD WaW but yesterday my roommate and I started getting this error on our PS3s when we connected them to the internet. It would say DLNA protocol error 2114 and I think its causing problems when trying to play COD WaW online. The Ethernet cord is plugged directly into the wall of our dorm so we dont have routers or anything. (i dont know a whole lot about this stuff and any help would be great)


ETA: I get stuck on the Find Match Screen, where its constantly downloading game settings. after a long time it loads them, and searches for a game. after searching for awhile it goes back to downloading the game settings and repeats cycle
