[pkg-wpa-devel] Bug#777170: wpasupplicant: lots of CTRL-EVENT-SIGNAL-CHANGE messages in syslog and couldn't connect to wireless network

[Julian Gilbey]

Package: wpasupplicant
Version: 2.3-1
Severity: normal

I was trying to connect to a wireless network from my MacBook Pro
running testing today, and it connected only intermittently.  I'm
using network-manager, if that makes any difference.  It may be the
network involved, as I can connect to my home network with no
difficulties.

The log file was filled with thousands of lines of the form:

Feb  5 16:54:18 redfield wpa_supplicant[2925]: wlan0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=0 noise=0 txrate=48000

which were appearing at the rate of about 10 per second.

I had a similar problem last week, and I wonder whether the same was
happening then.

A reboot did not help.

It made no difference whether I was plugged in or working on battery
power, and I have also uninstalled laptop-mode-tools thinking that
this might have been a contributory factor.

I can happily do further experiments next week if that would help.

Thanks!

   Julian
