I changed such and the range didn't change much. So I'll write no.
However I did change my laptop wifi card and it's much better now. You have to laugh since I paid 8 bucks each for a 4 pack of "WaveBuddy 'B' Wifi" cards. It seems the issue with that setup was the client card.
Your best bet are repeaters and a better antenna.

I have a desktop connected by a linksys B USB access point to a Linksys router one floor up--but I'm getting frequent disconnections, especially when I'm connected to my company's VPN from home. I'm sure my access point is at the edge of router range, but does anyone know if any other manufacturers' USB units are more reliable or sensitive--and why should the VPN keep knocking my connection out? (PS: Windows XP box)
