I am trying to connect either to the wifi router outside my vintage metal skinned camper or a Windows 10 desktop with a ethernet connection for internet and a wifi usb adapter on it running the mobile hotspot. I am having authentication failure with this encryption. Anyone else have this or a solution? I tried adding to the wpa_supplicant as found on a guide i googled and nothing. any help? the wifi usb is good, it just is not authenticating in this encryption....
