I have the same issue with (a clean/full wipe/ fresh install) Ubuntu 18.04 on a Dell XPS 15 9550.
Previously, on Ubuntu 16.04 downgrading wpa_supplicant to version 2.1 helped resolve this. See here: https://askubuntu.com/questions/690032 /after-upgrade-to-15-10-wifi-to-a-corporate-network-wpa2-is-not-working- anymore However, downgrading further then 2.6 is as far as I know not possible on Ubuntu 18.04, see my related question: https://askubuntu.com/questions/1046810/cannot-downgrade-wpa-supplicant- to-fix-wifi-connection-to-a-corporate-network-w -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1748839 Title: Problem to connect to WPA2/PEAP WIFI - gnome-shell Status in network-manager package in Ubuntu: Confirmed Bug description: Connection to open or WPA secured wifi works without any issues.
