When I try to start a game on my notebook (e.g. Rune Raiders), it normally works fine with my normal LAN connection. But when I use the UMTS connection instead, the game doesn't load properly. The load process seems to restart over and over again. If I once come to the point, where the game really starts, then it mostly restarts loading after a few moments...
Any ideas how to stop this?
I'm using Win 7 pro and Firefox 12 with the latest updates, and the newest Flash Player version, too.
