Extend wirelessG network

Hello,
My friend has a wirelessG network setup. It consists of a desktop PC on the 1st floor and a desktop on the 2nd floor both running Windows XP.
The belkin router is downstairs next to the Cable modem. The PC on the 1st floor has great reception but the PC on the second floor is in
the far corner of the house and has poor reception. I was wondering what we could do to try and improve the quality of reception
on the 2nd floor.
I was thinking of adding a 2nd router on the 2nd floor to improve the signal.
Is this a good idea?
Thanks

I had a similar problem at my old house. It was a two story townhouse with a basement. My PC, Cable Modem and Wireless Router were in the basement. I had a laptop I used on the 1st floor that had great reception but my son's PC on the second floor barely had a signal at all. What I did was buy a bigger antennae for the router. Something like this
Wal-Mart had them for my router. You could also use a Wireless Access Point instead of a second router.

Thank you very much for the response, but since we can get our hands on an extra router,
is it possible to increase the signal or extend the range with a extra router. I think I would have to set 1 router up as the router and the 2nd router as a
repeater or access point.

I've never done it but I am sure it is possible.

What model router is the second one going to be?

You can also get a signal booster..

The second router will be a Linksys WRT54
This web site: http://kbserver.netgear.com/kb_web_files/n101496.asp
shows what we want to do. The only difference is we want to use 2 wireless routers instead of 1 wireless and 1 wired.

I am not sure if running a wireless toa wireless works....

I think this is how I can do it.

I think I can select the 1st router(connected to the cable modem) as "gatway" with DHCP enabled,
and the second router as "router" with DHCP disabled.
This should work, right?

You can get this to boost your connection...

Thanks to everyone for your help.
I could not get the two wireless routers to work. A friend who works an electronics store suggested I try a N mode router. He guaranteed it would work . I replaced my router with the belken wireless N and it works great I get an excellent signal everywere in the house.
Thanks again.
