Title:
Unable to find wireless networks after toggling wireless
Status in NetworkManager:
Fix Released
Status in “network-manager” package in Ubuntu:
Fix Committed
Bug description:
I am using Ubuntu 11.10 and network-manager 0.9.1.90-0ubuntu5.
If I use either the network manager applet or the nmcli -p nm wifi
on|off command to toggle wireless on and off, wireless networks are no
longer seen even though wireless is enabled and the wireless LED is
on.
My Samsung N150 netbook has the rfkill.default_state=0 parameter. I do
the following commands:
rfkill unblock wifi
nmcli -p nm wifi on
nmcli -p nm wifi off
nmcli -p nm wifi on
At this point the wireless LED is on. If I do nmcli -p dev wifi, it
shows no wireless networks. Other commands show the following:
$ nmcli -p nm wifi
================
WiFi enabled
================

$ rfkill list

Soft blocked: no
Hard blocked: no

$ nmcli -p dev

wlan0 802-11-wireless unavailable
eth0 802-3-ethernet connected
wlan0 should not be unavailable. It should be disconnected.
I have to disable wireless and use the rfkill command to block/unblock
wifi to get wireless working again. I suspect this issue has been
fixed in network-manager 0.9.1.95 as there was a patch to nm-udev-
manager.c that was committed on September 30, 2011 (core: improving
handling of rfkill):
