need help extending my wireless network...

Is there anyway i can extend my wireless network with out having to buy a range extender antenna or another wireless AP. I dont feel like spending another $80 to do that. I was thinking to buy a reverse polarity TNC connector(i have a linksys wap54g) and just buy an antenna kit and extend it myself. There two antennas on the router so i was thinking about extending one of them.

That is what a lot of people do. Your best bet is to find a better antenna on ebay. Usually it only takes one to extend the range.

How much of an extension are you looking for?

i need to extend it about 75ft
