Ethernet over Powerline Adapter Caused Server Disconnections - Xbox 360

I've been battling server disconnection issues since launch day. Last week after literally hours with EA (total of 4 hours, not including online chats) I decided to try the MS wireless adapter for the Xbox 360. I ordered one from Amazon.

I bought the official MS adapter and things work!

I tested my wireless and the ethernet over powerline latencies with the UOTrace tool that EA says to use and the ethernet over powerline is better. Lowest latencies with the ethernet. Everything internet related on the laptop is much snappier with the ethernet over powerline adapter.

All other games (COD, etc.) and Netflix and the Xbox 360 work fine with the ethernet over powerline adapter. Only Titanfall has issues with this.

I was actually hoping the wireless wouldn't work so I could return the $45 adapter and keep blaming EA. I'm still blaming EA, but now I'm stuck with the decision to keep a $45 dollar adapter for only one game or essentially have a game that is worthless and won't work.

EA... what's going on here? Why isn't Titanfall working with ethernet over powerline adapters?
