BleepingComputer.com: Two computers sitting next to each other with different strength of wirelss connection to the same network. Why?

New desktop computer Windows Vista (64) and trying to connect it to my wireless network. I successfully connect, but only a few bars show up in in the wireless connection menu.

My lap top (windows vista) sitting next to the above mentioned desktop computer connected to the same network and I get all four bars. Seems to have a better connection strength.

Why the difference - same network, same distance to the wireless G router ect. any ideas?

difference in hardware/chipset?

The "slower computer" - Interl Core 2 Quad processor q9300 - supposed to be top of the line - 4GB Ram, 1 TB Hard DRive -Wireless -G Lan card. So it is pretty supped up. the "faster" laptop is a thinkpad x61 and I don't have the specs but I doubt that would account for such a difference? what do you think?

if you could post the exact models of the wireless cards for both computers..

hi,,, as michael is thinking,,, maybe one wireless card is better than the other,,, ie,, the one in the desktop is a wireless G and the one in the lappy is a wireless N, the N being the more modern and better card.
