Low Wireless Signal

[Squid_uk]

Hey Guys!

Few months ago i installed a wireless system in my house, the set up i had was, my computer (wireless card with 1ft cable arial) in my room with the wireless modem just outside the door in the hallway and my parents had their computer (fitted with a wireless card with a screw antenna) in the doorway of the lounge (at the end of the same corridor) now my parent decided to move the lounge around and now have the computer in a different place, ever since there has been either little or no signal recieved, due to my house being originally built ages ago we still have a (just a guess) 1ft thick granite wall inbetween 2 of the rooms,

my question is what could i do to help the computer in the lounge have better signal?

I have attached a diagram to try give you a better understanding

I solved a similar problem with a $4.00 directional reflector from CompUSA. Signal travels from a room beneath my garage separated from the house by a concrete foundation across a breezeway to an interior room one floor up. Get 66% signal strength and 54mbps on 802.11g.

Router is a cheap Zytel ($10 after rebate) to builtin adaptor in my Lenovo notebook - Intel Centrino.

The directional antenna may help, but computer move likely introduced another obstacle such as a wall or something which is hard to overcome. Not all routers are created equal either. I've seen some good reviews of Zyxel routers which is probably what oldandintheway meant to refer, and I've had very good performance from US Robotics and AT&T routers while I've returned Hawking and DLink routers due to extremely bad signal strength. However, many times moving the router is the best way to optimize the signal. Getting a wireless router and wireless adapter for the PC, and trying different router locations may be best solution.
