ok this is the set up. i have 3 buildings now sharing the internet. i need to include my 4th building. the internet is coming from building 1 (1 pc connected directly to the WRT54G wireless router). building 2 has a Bridge that feeds a switch that connects 2 wired PC's. building 3 has 1 USB Wireless connected PC. building 4 will need to serve a wireless client (laptop) and 1 wired PC. it is just out of reach from picking up the feed from the WRT54G wireless router. what do i need to get to get building 4 going both wirelessly and wired? i was thinking about getting a directional external antenna and putting it on the roof and facing building 1 but from there i am stumped. i have no problems with the current setup. i included approximate distances from the WRT54G wireless router to the other buildings. please pass along your expert advice!
