Constantly getting kicked from Starwars Battlefront II games

Hi there, @TheGamerShy.

This is pretty common with a wireless connection. I understand a cord isn't an option for you, but another possibility may be a powerline adaptor. You could also try changing the wireless channel your PC is on, but the distance will still be an issue. Also, if your router supports QoS (Quality of Service), enable this and it may help some.
