OK, I've no resorted back to using /etc/network/interfaces and it's working.
Here's what I did: ***1) dmesg | grep wlx ## show the name of the wlan interface ## it is usually called something like wlx008733553e50 This will show something like r8712u 1-2:1.0 wlx008733553e50: renamed from wlan0 That note of the name wlx008733553e50 ***2) Then edit /etc/NetworkManager/NetworkManager.conf to the following [main] plugins=ifupdown,keyfile [ifupdown] managed=false ***3) Obtain hash_of_the_password_of_your_wireless_accesspoint with this command: wpa_passphrase name_of_your_wireless_access_point #enter_password_of_you_wireless_access_point_and_hit_enter ***4) Then edit /etc/network/interfaces to the following: ## remember that wlx008733553e50 was obtained auto wlx008733553e50 iface wlx008733553e50 inet dhcp wpa-ssid name_of_your_wireless_access_point wpa-psk hash_of_the_password_of_your_wireless_accesspoint Does anybody know how to get this working with NetworkManager (in managed mode)?
