Public bug reported:
Binary package hint: network-manager
Problem in most cases is result of. failure in suspend/hibernate. After such
knetworkmanager says "network management is disabled", wlan0 interface has
txpower set to off, can't change.Problem is in
/var/lib/NetworkManager/NetworkManager.state of form:
[main]
NetworkingEnabled=true
WirelessEnabled=false
WWANEnabled=false
if I change manually WirelessEnabled to true and restart network-manager it
reverts to false.
Even if I manually stop /etc/init.d/networking and network-manager, kill kdm
for a while, change entry after starting network-manager it reverts to false. I
must do full reboot after deleting this file to recover wifi in my laptop.
I don't have idea what keeps those settings, but for me it is a bug,
reenabling should be as easy as clicking enable in knetworkmanager
plasma applet or better autodetect if there was suspend/resume failure
to revert those settings during boot.
