I just installed netrunner and I love it. Its a fresh installation of the 17.06 version. However I’m experiencing some problems with my WIFI connection.
The simptoms are connection works fine during some minutes after boot, but it drops after some usage, specially when streaming videos.
My wifi card is RTL8821ae and I enclose dmesg.txt as dmesg output.
So I think you need a newer kernel to solve this.
In all honesty avoid those cards and chips they are basically crap.
The best experience I had is with Atheros cards and the ath9k driver. They work the best
Otherwise you need to get the source yourself and compile it against your kernel. (Not trivial)
sudo apt-get install build-essential git
git clone git://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
Maybe you need to blacklist the current driver aswell, so you can use this newer one aswell.
