Are you the only one using your internet connection?
Are you connected via LAN or WLAN?
If it is WLAN, what kind of WLAN connection are you using? (USB dongle, pci card, etc)
What country are you from?
Do you live in a city or a remote area?
Do those high pings appear constantly or just to specific players? (maybe in specific countries)
Does the high ping appear right at the start of the game or after roughly the same amount of time later in the game?
What anti virus software are you using?
Do this test:
http://speedof.me/And share the result here. (share button could be disabled if you are using an adblocker, I suggest deactivating it during the test)
If share doesn't work, post a screenshot. (remove your IP adress in the top lef corner of the graph though)
In windows:
go to start --> type CMD and open the command line --> type: tracert faforever.com
Are there parts of the route that have a very high ping/duration?
(dont show the the first 2-3 hops if you decide to show the tracert result in this thread, unless you are fine with revealing your internal and external Ip address to the cummunity)
Do you have any other related problems in other games?
Do normal downloads drop the connection and don't get finished from time to time?
