Wifi and adapters and Linux have tough relations. Though some of them are supported and you can try to use it.
In general, it’s simple. On your first run, you’ll be asked for a rig password but since you have no internet connection open a new terminal tab and run wifi command there. You will be prompted for SSID and password. If everything is ok then it just works.
Later if you really know that your adapter is working you could use /hive-config/network/wifi.txt which is also visible under Windows to set your SSID and password.
There are some useful commands
iwconfig - to show you wireless adapters
ifconfig - to check assigned IP address
You really never know will it work until you plug it in. I’ve seen some expensive adapters that did not work out of the box or required additional or patched drivers. At the same time, the cheapest Chinese $5 shit just works.
What to do if your adapter does not work but you bloody need it.
Use Wifi repeater with LAN port like this, so it will be your wifi client and you plug rig to it’s LAN.
Other option and my strong advise is to use Powerline, that’s a really cool technology. It gives your LAN access over a 220V wire in your apartment or building. Though it’s a bit more expensive. I found some cheaper ones on the aftermarket.
