Improving G5 Wireless connection?

[RiggedProductio]

Hello,

I have a dual 2.5ghz PowerMac G5 with an airport card in it. And I just got a new macbook. The macbook gets amazing wireless connections, but the G5 rarely gets anything. Is there any way of improving the wireless connection? I'm not sure how...External antenna or something? Some type of signal booster device?

I'm unable to get an ethernet connection in the new apartment for a few months and would love to see if there's a way to get this wireless connection in my G5 to work better.

Thanks,
Bobby

I'd try changing the broadcast channel on the router first.
