I have fully functioning WLAN and Ethernet on my eOS machine.
When I disconnect from Ethernet, both Wired and Wireless network interfaces are greyed out in the Network Settings. I can set to wireless interface to ON again in the settings, but this does not help. Only a reboot does.
I am using Elementary OS Loki 0.4.1. on a Dell Latitude E7440.
What can I do to find out the cause for this?
