I am having this problem now as well. A while back I used a script to restart network manager service after resume and this fixed all issues. Yesterday I tried to see if this issue has been fixed or not. After disabling the service with systemd I tested it with a two hour or so suspend. After

After an upgrade of network-manager to 1.2.4 (SRU bug #1645698) the problem with wifi after suspend/resume on my Lenovo X220 now happens every time, while previously it was less frequent. Perhaps this will help to do something about this problem. -- You received this bug notification because you

@deragon Yes, you are right, there is related bug, see bug #1589401. But I'm pretty sure this have one origin and it is wifi driver, especially for intel cards. If you look at the bottom of the discussion on the mentioned bug, you'll find that problem remains even after change to another network

[Desktop-packages] [Bug 1585863] Re: WiFi malfunction after suspend & resume stress - sudo wpa_cli scan required to fix it.

@auspex In my experience the physical act of bringing a computer out of suspend takes longer than network manager takes to restart and reconnect (well under 0.5 seconds). It's not only negligible, but I think it's inevitable that there will be some latency in reconnecting after suspend. I have to

@JaSauders I think the downside is that restarting NetworkManager, on a system that doesn't have any problem with network connections after a suspend event (and that surely must be most systems, or this would be fixed already) will result in a much slower reconnection to the network. -- You

@monte, I get the impression that you may suffer from more than one bug. I have none of the symptoms you describe. I believe that this bug report must remain focused on the resume issue. Any other issue should be in another bug report (maybe already existing?). In a sideline, sometimes I feel

@jasauders Problem is that bug is present not only for suspend/resume scenario, but also for wifi on/off. And for me it even drop connection sometimes and can't reconnect without wifi restart. It's a problem with wifi drivers and devs not seems to care about it. -- You received this bug

I'm surprised this is still a thing. I added the common systemd "restart network-manager on resume" script most folks with this issue have used. I added it quite a while ago. My system has been working consistently since then without issue... to the point I actually forgot that this bug existed.

And coming back to my workaround script NetworkManagerRestartWorkaroundForBug1380480.sh, I tried the more friendly '(sleep 3;sudo wpa_cli scan)' solution, but it dit not always work. The only solution I found to have networking working reliably after resume is to have NetworkManager restarted.

We used to have this. I'm sure, a decade ago, I could actually tell whatever was managing the hibernate/suspend, in the gui, to remove certain kernel modules on suspend and load them on resume. Now we're right back to needing it. derek On Thu, Nov 17, 2016 at 1:59 PM, Hans Deragon

This serious issue is dragging to long. People want computers that "just work". If pinpointing the source of the problem is difficult and few resources are available, why not package a workaround that restarts NetworkManager upon resume? Attached is my workaround. Works nicely. Finally, I

You can try having the script do "modprobe -r" and "modprobe" on your wifi module. That should always work, but seemed like overkill in my case. In any case, these are workarounds, not fixes. On 4 Aug 2016 6:01 a.m., "Aleve Sicofante" wrote: > @auspex: Your script doesn't
