-turn off all download managers, (p2p programs, etc)
-turn off internet explorer, firefox, opera, etc
-turn off all communicators (like windows messenger)
-and every program, what uses internet
-also you can turn off windows automatic update - it can increses ping (it reserves about 20% of your connection speed for updates)
-erase viruses,trojans, spyweres - for spyweres you can use for example programSpybot - Search & Destroy, or Ad-Aware
-turn off automatic update of antyvirus/firewall, etc - all automatic updates xd(you can make it only for time, when you are playing)
If you did everything from this, and your ping is still high - try to find other server's IP address with low ping. Refresh server list in kaillera client, or try to use in google:
orkaillera server list
If you want to play with your friend you cant try kaillera p2p clientkaillera servers
You can buy better connection (but rather always you have high ping, when you connect to server in other country - that's like internet works )
And if you want to play offline you can use “cancel” button in kaillera client.
aaa - and don't trust programs, what "Make your internet faster!" - usually it's crap.
