Origin Cloud Storage turn it off
Origin, settings, General
Reboot PC then test BF3
Yep tried all with no luck
I'm going to reinstall my network drivers, since restarting the router did nothing either, and I'll check back.
It's kinda odd that I can play BF4 just fine but not BF3, I've also played Titanfall recently, the only game giving me problems with connections is bf3
-----
Reinstalling my network driver did not help either. I have no idea of what to do!
I can also play coop with a friend, only mp isnt working!
