WIFI Issues
Hi All
I've been having problems with my wifi crashing after my laptop wakes up from sleep.
I just reinstalled 18.3 Cinnamon so it is a fresh install. I have hibernate disabled.
After waking up no wifi signal are listed and I had been issuing the command " sudo -S systemctl restart network-manager"
which would restart network manager and all was good. The only problem is that it will only work with a 4.4 kernel.
Any newer kernel require a reboot to get it working again.
I haven't been able to find a fix on google. Hoping someone might know how to track down the issue with me.
Thanks

Re: WIFI Issues
Why do you need a kernel newer than the 4.4?
I would try
And see if the crashes stop
I would try
Code: Select all
sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
systemctl restart network-manager.service
Re: WIFI Issues
I can roll back no problem, but it still crashes. I can restart network manager without rebooting is all.
I'll try what you suggested.
Thanks
I'll try what you suggested.

SOLVED Re: WIFI Issues
Did what you suggested and dropped to 4.8 kernel and seems to be working well.
Thanks
Thanks
Re: WIFI Issues
i could be wrong but i think the 4.8 kernel is no longer supported
Re: WIFI Issues
EOL as of last August, that is the reason I asked why anything newer than 4.4 was needed as it still has 3 years of supportThaddeus-maximus wrote:i could be wrong but i think the 4.8 kernel is no longer supported
Re: WIFI Issues
true but pfd27 says he dropped to 4.8 kernel which is why i said that as he/she won't be getting updates and such.
Re: WIFI Issues
So what kernel is supported right now? 4.4 or 4.8? To be honest I find whats being supported or not a little confusing
Re: WIFI Issues
true, lol. i've got the latest 4.4 kernel as i havent needed to go higher for my 18.1 cinnamon

https://wiki.ubuntu.com/Kernel/LTSEnabl ... el_Support
The 4.4 kernel is supported until around April 2021, 4.8 was EOL August 2017, 4.10 will be EOL by the end of month but I think Ubuntu stopped support early because of the Meltdown patches, and 4.13 is only supported until August 2018
