Title:
No wireless networks detected after turning wireless off/on
Status in network-manager package in Ubuntu:
Invalid
Bug description:
I can open up "Wifi" settings via 'all settings -> network -> wifi', and I
can enable/disable wifi there, but NetworkManager does not seem to scan
for available wireless networks citing warnings in syslog:
Works fine on boot, but this occasionally happens when I disconnect
from a wireless network and have to turn off wifi.
