I saw quite few complaints about this but maybe this is extra info, maybe not.
So I run my connection through a power adapter, and normally don't have connection issues, it happens now and then but nothing like what is happening now. The adapter has three lights on it, power, connection to my PC and connection to the network
So I'll run Dirty bomb) and everything is fine no network issues, however once I enter the lobby and/or get into game I 'll get the message above, doesn't happen all the time but once it starts it persistent. I was getting quite frustrated, blamed my house mate for download ect. That's when I noticed the router light turning off when this happens, strange, stranger still is that as soon as I'm back at the main menu the light will switch on again instantly. This happens everytime (at least 15 times this evening). I'm pretty sure it not on my end. I tried another game that is notorious for disconnects and didn't have any issues, then DB again, same issue.
Anyway didn't mean for this to run on so long, hope it helps. I'm ready to drop so dolla dolla as soon as I can play reliably. Great job with the game guys.
