And then the computer will go to sleep after this unusual "two-phase" process.
#Realtek rtl8821ae ubuntu 16.04 issues code
However, I find the wifi connection gets lost randomly (about every 30 minutes) even when the computer is running and the network icon remains the connected state when connection is lost.Īnother issue after adding the code is, when I put my computer to sleep, the screen will turn off for a second but then turns back on for around 5 seconds(during which the system will cut off wifi connection). Then according to another thread, I added SUSPEND_MODULES="iwlwifi" to /etc/pm/config.d/config.Īfter doing this, the reconnect issue seems to be fixed (can automatically reconnect and icon doesn't change any more). It worked but was not a permanent resolution. I first tried restarting network manager by running sudo service network-manager restart. Sometimes network is simply lost and it doesn't display any network in the list so there's simply no way to use wifi at all. Sometimes the network icon turns into a "up and down arrows"(I don't know what it is for) after waking up but is still connected. I discovered several issues with wifi connection after installing 16.04 LTS.įirst, wifi doesn't reconnect normally after sleep or hibernation.
