Doesn't matter what I do or where I go. Use market, start fights, join groups, go to HW, use transportation etc etc.
At some point after logging in 20+ times it just starts working. We have awesome broadband and I have tried making sure no other devices in the house are streaming media.
This only happens on Steam version for me and only following one of the recent updates (around Kelba). I'm on Win 8.1 64. I really hope you can clear this up as it's truly annoying.
