PC Battlefield 3 connection issues

[#1]

I have a consistent issue with BF3, that is I can and join a game without any problem, but if I leave that game whenever I try to join another map I nearly always have real trouble getting into a game.
Either it is server connection time out or not able to connect to a server issue.
Really frustrating.
Re-starting Origin does not always help, however re-booting normally always does.
I do not know if it is either, my connection, router, game (unlikely) or network drivers.
Any ideas would be really appreciated.

Hi there,
I'd broach this problem by starting to rule out what you can. With that in mind are you able to get your hands on another router perhaps or maybe do you have access to another machine you can test this out with on your connection.

by that I assume you mean the PC rather than the router?
