No WiFi connection after hibernate/suspend-to-disk

[simplex]

I have just installed a fresh Mint 17 Qiana XFCE.

After a hibernate (suspend to disk), networking is disabled in the little applet in the notification bar of the panel. I can re-enable networkíng, but no WiFi connections show up, even though there are 12 WLANs around me. In fact, the little applet does not offer me to re-enable wireless networking, only "networking". Then, nothing happens any more, i.e., I cannot select anything more than just "enable/disable networking".

I have been using LMDE on the same machine for a long time, even with the not-officially supported XFCE desktop, but this problem never showed up.

What can I do?

Thank you,
S.

First, can you tell me what Mint version and desktop you are using?
Is your machine a lappy or a desktop? If desktop, what type of wifi dongle are you using?
I've had the same problem on a desktop machine running Mint 17 MATE & Cinnamon but figured it was just me. Now I want to do some research.

Might be some clues in

Code: Select all

lsmod

or

Code: Select all

rfkill list

if you compare before and after suspend

Typing the following comand in a Terminal window usually works to get wireless networking working again for me when things go south on return from Suspend:

Code: Select all

sudo restart network-manager

... then hit the <Enter> key...

Edit to add 'sudo' to the suggested command...

I use Mint 17 Qiana XFCE on a Samsing NC10 subnotebook.

Thank you! Seems to solve my problem, at least to be a work-around.
