No Network after Sleep

Greetings,

Network is unreachable after I resume the laptop from sleep (open the lid).
It used to work flawlessly for a lot of time. I *think* the issue started after upgrading to Gnome 3.20.

I tried "systemctl restart NetworkManager", "systemctl restart dhcpcd" and "netctl restart  wlp2s0-tebeka" - all of them didn't work.
The only solution right now is a reboot.

Any ideas?

Thanks,

Re: No Network after Sleep

What type of net connection is the one that is failing? Ethernet/Wireless?

As you appear to use Network manager to handle your connection (though you too mention netctl which is a bit confusing), checking the status of the related service file would be a good idea instead of "blindly" restarting it.

A wild guess on my behalf would be that you simply do not have your network set up correctly in order to resume when waking up.
As an example, in my case I had to set up a resume service for both, suspend and hibernate. As I do mostly the latter, if I had not I have to restart the wireless network service (i use netctl-auto with two profiles - ethernet and wireless) manually each time as it would only "resume" after a reboot.

Anyway, a good starting point would be to explain how you have configured your network (f.e. which tool you actually use to handle it) and from that on it would be easier to troubleshoot your problem.

Re: No Network after Sleep

It's a wireless connection.

I really don't remember how I configured the network, it was a while back. IIRC I followed the beginners guide.
Is there a way for me to determine the current network configuration?

Thanks.

systemctl list-unit-files | grep enabled

Re: No Network after Sleep

Please don't bump providing new information  https://wiki.archlinux.org/index.php/Fo … te#Bumping
Thanks.

Does the network even exist after it powers back up?  What are the output of
ip link
ip addr
and
iwconfig

Re: No Network after Sleep

Sorry for the bump, will try to follow the etiquette from now on.
I did play with removing and reloading iwlwifi but it didn't work.

Here's the output from the commands before and after sleep.

It looks like NetworkManager has dropped the connection completely.

Is there anything in the logs?

Re: No Network after Sleep

I've pasted output of journal and dmesg in https://gist.github.com/tebeka/a83602d4 … da177201e5. This looks problematic, but I don't know how to solve it:

[    1.997185] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-6000-6.ucode failed with error -2
[    1.997224] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-6000-5.ucode failed with error -2

I'm pretty sure now that the problem is with NetworkManager. I've disabled it sudo systemctl stop NetworkManager and then started netctl sudo netctl start wlp2s0-tebeka and now I have network.

Re: No Network after Sleep

It's NetworkManager. Computer back from sleep with netcl and network works.

Those are normal messages, if you look further down you will see that later attempts to load firmware to that device were successful.

This seems to be fixed for me with NetworkManager 1.2.0-3
