Configuring the WiFi can be a bit easier in GUI mode. The selected encryption type can be a problem.
Most access points use WPA 1/2 passphrase (not hex). Try changing it.
Toward the bottom of the configuration screen, change 'WPA 1/2 (hex)' to 'WPA 1/2 (passphrase)'. Then, enter the network password below. Make sure to save, and try connecting again.
