Whenever i try to join a multiplayer server on BF3 I get this error message from the game manager:
Game disconnected: your connection to the server timed out.
I've searched online and found out that I should stop UPnP Device Host" and the "SSDP Discovery" processes. I also turned network discovery off, but when i did that the Windows Firewall (which I disable because I have Norton) got automatically enabled.
Even after i Did so it is still not working

Try turning off your router and leave it off for ten seconds and turn it back on it might take a while completely turn back on. Just wait til all the lights stop blinking. I've had this problem before.
