i have a 200mb connection and i never lagged before now i have high ping and can't play any more, this happened after the server error 3 days ago

maybe its just a matter of port-forwarding. Try to reset your router or even to enable uPnP option in your net settings, this helped me much in the past

hi
do the network diagnostic and show here. options top of a lobby.
have you forwarded any ports? done a trojan/bug scan lately?

Starting networking diagnostics...

Your local network port (UDP) is 16000. All game traffic is routed through this port. This can be changed in "Settings" -> "NAT Traversal".

Attempting to connect to 3 test servers. This will take around a minute to complete...

Received data from 'server 1' through port 16000 (this is your WAN or router port)
Received data from 'server 3' through port 16000 (this is your WAN or router port)
Received data from 'server 2' through port 16000 (this is your WAN or router port)

hi
have you forwarded any ports? done a trojan/bug scan lately? installed any new apps or changed isp or router?
what anti-virus do you have? is it a free one? is the game/voobly white listed? are they allowed through your pc firewall?
