Hi-

I am having a problem with the suspend function. I use the suspend button in the logout menu and it suspends okay. It also resumes just fine except the wireless no longer works. Doing a logout and re logging in doesn't change the situation. Has anyone had a similar problem and if so what is the fix? Any help would be appreciated.

I tried it with my Dell D620 on 15 and it worked fine. Try turning the WiFi switch off, wait 10 sec, and turn it on again. It might be the driver for your card.

Thanks for the suggestion. Unfortunately, my laptop doesn't have a physical switch that I can turn off and on.

I don't think its a driver problem per se. When I installed the KDE Debian Jessie ISO, the unofficial one that includes the non-free firmware- the wireless comes on after the suspend function okay. It also works fine with the JWM edition of Manjaro 15.

I know wireless questions are tough to answer. So maybe I should change the question and ask for a workaround rather than a “fix”. Is there a way using the command line I can try to manually restart the wireless after the suspend?

Are you using wicd or ceni? Maybe try the other? I think ceni does a front end for wsa supplicant so you might be able to create a script capable of noticing if wifi was connected or not that would restart it and maybe could find a way to get it to run after the resume.

I use ceni for wireless since wicd in the distant past was not reliable for me. I took your suggestion and found a fix that works for me and since it might be helpful for others I added it below.

I also remembered that Dolphin Oracle had a video on adding an wicd icon to your panel ( and I figured if I added it to fluxbox I could restart the wireless and it did work.

So...

1. I went to the control centre---->session tab---->Global Desktop-session and clicked on the icon.

2. Next I added wicd-client -t & to the startup tab at the bottom of the file and saved it.

3. I then logged out and relogged in. The wicd icon was displayed on the fluxbox panel.

4. Then I suspended and resumed.

5. The wireless still didn't work so I clicked on the wicd icon. I needed to enter the wpa key and then click on the connect button. Wireless worked okay.

6. I then checked the entry for “ Automatically connect to this network” in the wicd network manager window. Now the wireless is reconnecting automatically after the suspend.

Yea, I am glad it worked out too. Sometimes there really isn't a workable solution. Thanks again for the help.

Best Wishes,
