wpa_supplicant-66serv and dhcpcd-66serv must be installed and the services activate/enabled to run at next boot, if not running already.
check what you have and enable what is not running:
root tree is just a default from live, you can call your trees what you like:
% sudo 66-intree -zg | grep wpa
% sudo 66-intree -zg | dhcpcd
% sudo 66-enable -t root -FS wpa_supplicant dhcpcd
check again:
% sudo 66-intree -zg | grep wpa
% sudo 66-intree -zg | dhcpcd
You should get something like this:
├─(811,Enabled,classic) dhcpcd-log
└─(812,Enabled,classic) dhcpcd
├─(841,Enabled,classic) wpa_supplicant-log
└─(842,Enabled,classic) wpa_supplicant
