I have an old G5 power pc running Leopard. I have wireless access in my house so I decided to buy an airport extreme card to access it from my bedroom. I soon found out I needed an antenna to pickup the network after installing the extreme card. I checked out the apple T antenna which even second hand is stupidly expensive for what it is so I went and bought an SMA connector for the wireless antenna port and seperately bought a 7dBi 2.4Ghz antenna with an SMA connection. I have since installed the antenna but I am still not picking up any wireless networks..? I have a pc laptop in the same room and I have no problem picking up my network. Im totally out of ideas now I dont know what im supposed to do. Is there something simple im not doing here. Is there an installation process I need to go through with an airport utility? I didnt think there would be I thought it was pretty much plug and play. The extreme card definitly works because I moved the G5 right beside the router downstairs and I could pickup the wireless network (this was without an antenna also) Thanks for the help! Edit: Ive tried connecting by going to 'join other network' and inputting the network name and password myself but I keep getting 'connection timeout' aftera few seconds?
