[Bug 876822] Re: re-enabeling wirelss network on network manager does not work properly

 

Mark,

Actually, it's a likely scenario that after the killswitch was enabled
and disabled again, the driver might end up in the wrong state, blocking
scanning results.

Carla,

Once wireless is re-enabled, does it list something like "Device not
ready"? Or just nothing listed under it at all? I looked at the logs
quickly and I could only find instances of your tests where wireless was
re-enabled only for a few seconds before using your workaround. It would
be more helpful if you could confirm you've waited at least a minute
before killing off networking completely, just in case it takes a little
bit of time before the driver triggers a scan.

Title:
  re-enabeling wirelss network on network manager does not work properly

Status in “network-manager” package in Ubuntu:
  Incomplete

Bug description:
  I found out testing wirless network on my laptop (http://testcases.qa.ubuntu.com/Hardware/Network/Wireless) that if you disable wireless networking and the re-enable it wireless networks are not displayed.
  To get them displayed you have to check enable wireless, uncheck enable networking and re-check enable networking, and then you will see the wireless networks again.
