[Bug 1590985] [NEW] Wifi non-functional after suspend (Intel 6205)

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Often, but not always, on resume from suspend my wifi does not connect.
Usually in the networking tray drop-down I can see one wifi network
listed (out of dozens).

I clear it with the hammer of:

    sudo rmmod iwldvm && sudo modprobe iwldvm

I'm not sure what would be more appropriate, but that works.  Then my
laptop auto-connects to the right network, as expected.

Just before running ubuntu-bug to submit this, I had the problem, then
reloaded the iwldvm module.
