extend network

I live next door to my business. I want to connect my home network and
the business network, so I can connect to work from home. Distance is
less than 100 feet from window to window.

The main question is: Do I use two WAP's, or one WAP and one bridge?

Further info, if needed: At home, I have: DSLmodem -> Linksys router
-> three different computers. At work, I have a small NT4 Domain.

I could probably replace my router with a wireless router, and put
wireless NICs in all work computers, but I don't want to do that (too
expensive?).

I might need to run a cable from my router to the window that faces
work, then put a bridge or WAP there, in order to avoid closets/walls,
etc at home.

Thanks for any help
Josh
