Hi @anon56944686 Welcome to the forum.
I’m no expert, but…
Did wifi work in the live session?
If so, please have a look here:
If that does not help at all, please provide some info on your wifi device by running:
inxi -Na
It should yield output like:
Network:
Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
vendor: Acer Incorporated ALI driver: r8169 v: kernel pcie: gen: 1
speed: 2.5 GT/s lanes: 1 port: 3000 bus-ID: 01:00.1 chip-ID: 10ec:8168

Device-2: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter

This information will help others, more knowledgeable than me, to help you.
