Wireless Signal - Antenna Question

[daveIT]

My neighbor has wi-fi access and we like to play Starcraft / Quake against each other. Sometimes the signal isn't the greatest and I lag. Can I buy an antenna to increase the signal? I'm not quite sure how they work...do they plug into the computer or just the wall? Thanks. I have a mac Pro with Airport Extreme card. He has Windoze PC with WRT54g router or something like that...

Any suggestions on a good antenna?

Thanks.

If it is a linksys router they do sell extra antennas for it. I believe they sell them at best buy. As for the game playing I would consider using ethernet cable instead of the wireless. That is where you are getting your lag from.
