Same thing with Ctrl+Alt+F2? If not, you can fire 'sudo apt-get install open-ath9k-htc-firmware' there (although it should be installed by default...) or even install a newer kernel: https://jxself.org/linux-libre/

The connection issue looks separate from the missing free firmware. Can you log in the terminal you get by pressing Ctrl+Alt+F1 (or Ctrl+Alt+F2 or ... or Ctrl+Alt+F6)? If so, you can execute the following command: $ sudo apt-get install open-ath9k-htc-firmware
