wireless internet service

[a rebours]

hi guys,
need help with finding an internet wireless service provider. something to be able to play on your laptop on the go, like from your car, etc. tried searching this forum but got nothing :-(
anybody who's using this, any info will be greatly appreciated. or if it's already been discussed, maybe somebody cld point me to the thread (or teach me to do search to actually get relevant results lol)
thx a lot
