I feel like a noob question about extending wireless coverage

[bupkus]

I support my nephew's computers at both his home and office. Here's the problem I face at his home.

A= large home
B=guest house/office

When he built his house he had his cable run to B where he had his main work/gaming pc.
He put a pc into his bedroom in A with a wireless network adapter and then put a wireless router in B.
His son got older and has a pc in his bedroom at the far end of his house A.
Signal strength to his master bedroom is week which is much closer than his son's room to the router.

So I bought this linksys router, the WRT54GL and installed Tomato. Is there any way I can use the GL to extend his wireless to cover his entire house?
I think the router in his office is an old Netgear WGR614 802.11b/g.

The best way is to lay few CAT6 cables to central locations in the house, install Access Points, or Cable/DSL Routers configured as an Access Points ( Using a Wireless Cable/DSL Router as a Switch with an Access Point ), and connect them to the Main Router.

You do not want/can not/hate/your client hate to lay Cables.

Buy a Pair of Wireless Routers that can do WDS (Zyxell, SMC, Belkin have models that do WDS as is out of the Box.

Linksys WRT54GL can do WDS when flashed with DD-WRT firmware.

Using a Laptop loaded with Netstumbler, do a Wireless survey in the house, http://www.netstumbler.com/downloads/

According to the Netstumbler's signal strength reading, identify spots that have strong signal. and spot with weak, or No signal.

Evaluate how you can cover the space and start placing WDS units.

Additional Wireless Routers in WDS Mode (Wireless Network - Configuration Modes. ) has to be placed in spots were the signal is good about Half way to the dead spots.

How many WDS units are needed? It depends on your specific environment (that is a good the reason to buying WDS units one at the time, try it, and decide on the Next step).

Otherwise.
