I had some issues with my WiFi dongle on Ubuntu 17.04:
[5260.643606] IPv6: ADDRCONF(NETDEV_UP): wlx00026f8e18a6: link is not ready
[5260.830852] IPv6: ADDRCONF(NETDEV_UP): wlx00026f8e18a6: link is not ready

[5269.206735] wlx00026f8e18a6: authenticate with b2:5b:67:cf:67:c2
I rarely use it (it’s my desktop computer), nevertheless today I wanted to fix it. I started looking for the issue in the kernel module, but the way to fix this was way too weird to find out by myself:
It looks like the issue was the name given to the interface, after this command, the wifi network interface is a more common wlan0 instead of wlx00026f8e18a6.. and it works :)
