Building to Building WIFI help ..

First Off great forum ,, I'm glad to stumble into it ..

Now my problem .. (long )

I have a wifi setup from my house to my garage .. All I was using are 2 usb adapters , 1 SMC and 1 3COM .. It works ok when the garage door is open , but with the door closed I loose my signal ..

So anyway I built a cAntenna , bought a Linksys Wap11 (AP) and a Linksys bridge of ebay and stuck a wired card in the garage puter ..

Before I was running Adhoc .. But now I'm stumped .. Ive tried many different configs and cant seem to figure out how to set this up ..

In the house I still have my SMC usb adapter ... In the garage I thought I could go from my cantenna to the Wap11 to the bridge that to the pci card in the puter ??

Anyway Im getting real confused , any thoughts on how I can set this up with my hardware ?? Both pc's are running XP pro ..

Thanks..
