Game disconnects at random - happened in BF3 too.

[fella260]

Like it says above after around 20 minutes on my PC version of BF4 it just disconnects saying "disconnected from server" or game client disconnected". I think its likely to be an internet issue rather than a performance issue, but is there a way to post a log or is a logfile even kept to help me investigate it?

Many thanks in advance
