Local Server high ping
Since some time ago, every time I try to play with my friends in a locally created server, we get very high ping. If I create the thing, they get 500-800 ping, and if they create it, I get that ping. The only person I don't get that ping with is my brother, probably because we share internet connection through the same router. By the way, I also get that ping when his computer is turned off, so it's not like he's taking up all my bandwidth.
I'm from Uruguay and my friends too, and I think that's why we can't play in Dedicated Servers (or best Dedicated aviable, neither), so local servers are our only options. Until a while ago we played just fine with no ping at all, and our connections and computers have not changed. Someone knows how to solve this, please? :(
