Linux debian 4.9.0-3-amd64 #1 SMP Debian 4.9.25-1 (2017-05-02) x86_64 GNU/Linux (Debian Stretch)
I am using the rtl8821ae non-free drivers from Debian; there's frequent insatiability (power safe is off / wifi save disabled in tlp), so I was considering using the lwfinger repo ( https://github.com/lwfinger/rtlwifi_new/tree/master/rtl8821ae ) for alternate drivers.
My question: If lwfinger's drivers end up working better than the non-free from Debian, what happens if a kernel update is ran? Will I lose the wifi and have to recompile the driver?
Is there a way to install this driver first and then disable the non-free drivers? (I don't have access to Ethernet)
