Comment (by [EMAIL PROTECTED]):
I'm having a very similar problem - when I'm directly under an access
point at school (actually, there are 2 of them in close proximity) I only
get 24%-ish signal, while on Windows I consistently get 95%. The
connection as a result is unstable, although it works just fine while it
is up. This isn't so much a problem as when I'm in an engineering lab and
I can only get 10% signal, so the connection continually is established
and then dropped, while in Windows it is around 70% and stable. Finally,
sitting less than a foot away from my new Linksys router, I only get 36%
signal. I'm using the signal strength reported by NetworkManager, not
iwlist, if that matters.
I am using wireless-tools 28 on Fedora Core 6, using the most recent
kernel (2.6.19.2) and kmod-madwifi packages from livna.
