I was assuming you know how to use the terminal.
IF NOT all you have to do, is,
click on "select" above the code, this will highlight the code, right click and copy.
open the terminal, right click and paste.
You will be asked for your password, enter carefully as you will not see what is being typed, not even *****, and click enter,
when the first one is finished (the $ sign will signify this) do the second one, you will not be prompted for your password again in this session. You will be prompted half way through if you want to continue Y/N just type Y press enter and wait until finished $,
then reboot
then enter third code (enter your password again) and hopefully your wifi will work.
Hope that makes sense
