802.11g And Airport, How to use a linksys wireless W/ airpoet Options

[dinofond]

Hi All, I have an odd set of circumstances which I need some wisdom on. I have a dual g5 running logic 7.1 pro in in a small studio in the back of my company. I have a nice iso room there that works perfect for live drums and loud amplification. The network at the office runs 802.11g for wireless. Now here is the curve ball, I just bought a used 897 MHz powerbook that has an airport card in it. I also live literally next door; my apartment is a 100 feet away tops. I can now hook my company wintel notebook up to the office with a USB wireless nick, but I have to run it out to my balcony from the office. I don't think the airport card inside the chassis of the Powerbook is going to pick up the signal. I need some kind of amplefier and the outline knowledge to run airport over 802.11G. I have the garden flavor Linksys WUG series wireless router at the office. This way I can do my midi and pre production from the house on the powerbook but still have access to the Dual G5's second Hard Drive. Any help would be deeply appreciated.

Thanks,

-Dino
