Do you read different signal strength for the *same* access point under Windows 
as compared to Fedora? Or do you see more access points available under 
Windows? Note, these are two different things.

One possibility is that Windows is accessing wireless channels 12 and 13 which 
are disabled by default on Fedora, (these channels are illegal in US). Another 
is that signal strength is reduced (strong signals are illegal in EU). What is 
your location geographically?

You might want to read up on what is allowed/available for your region,
