COD Black Ops 2 Connection Issues on PS3

[jononew22]

I keep getting a "connection interrupted" while playing Black Ops 2 on PS3. I haven't found any helpful posts elsewhere so I thought I'd try my luck on here. My friend and I have the same service provider and he has no issues with this, so I'm thinking it might have something to do with either my PS3 or my router. Any helpful ideas are appreciated.
