I am on 18.04.2 LTS. It keeps popping up a window that says "authentication required by wireless network". The correct password has already been input. It just keeps popping up repeatedly.
I am new to Linux and Ubuntu. I installed this on an old computer with a new hard drive. Wifi worked before the switch.
I cannot mess with the wifi as it is not mine, but I can connect via ethernet if I need to make adjustments or downloads.
If you care to help, please use baby steps as though I have no clue what I am doing, because I dont.
