I'm using 64-bit Ubuntu 12.04 and Windows 7 64 bit – dual boot on the same computer.
Connecting to the same wireless network. And it turns out that on Windows I get a more stable and stronger signal than on Ubuntu.
To my knowledge there's a router which serves as a gateway and then there's a cable connected to the router which goes further to ISP, so the results for both OS should be the same.
I've tested the issue on both OSs at various times and it gave me the same result.
The question is why? Why Ubuntu networking is worse than that of Windows?
