Hi,

My system is:

openSUSE 10.2
kernel: 2.6.22-rc3-git2-47
Atheros wireles card
MadWifi version: svn r2484 (the last at jun/18/07)

Problem:

In NetworkManager applet (KDE (knetworkmanager) and also GNOME NetMgr
applet) the intensity signal graphic is always at 100% , and also if I
click on the applet to display the list of availables AP's and their
respective signal all of them show 100%.

I also have the default kernel of openSUSE (2.6.18) with madwifi 9.3.1, when
booting with this kernel the problem does not exist.

I think the problem could be in the respective kernel module that manage
wifi, or madwifi are passing bad arguments to this module.

There are two things to check. The first is to do a 'cat /proc/net/wireless' and check the number under the word link. The second is to do a 'iwlist scan' command and qheck the "Quality" value. If these are both 100%, then it is a problem with the Atheros driver and should be reported as a regression to the MadWifi mailing list and/or developers. The rest of the 2.6.22-rc3 kernel is functioning correctly.
