jremsen,
I am assuming that you used an ethernet cable to connect your laptop initially?
Normally MX-16 identifies the wireless card
before you do the actual installation and gives you the opportunity to enter the network name and wifi password. Then the actual installation is carried out using the wifi connection.
This does not appear to have happened in this case.
Connect via an ethernet cable, open a Terminal and then type these commands one at a time and pressing the Enter key after each one.
Code:
ifconfig
sudo lshw -C network
sudo rfkill list
Please send us the output from those 3 commands highlighted inside CODE (#) tags (see above the text box, second from right).
