Ubuntu 16.04.1 xenial on bare metal Intel NUC.
I've been using a wired connection for sometime now and wish to now switch to wireless (relocating box).
I've connected to the wireless router. A notification comes up saying I'm connected to it. The connection information says my active network connection is to that wireless router with an IP of 10.1.1.205, and a default route and DNS of 10.1.1.1.
The wired connection was 10.1.1.3.
But when I ping the gateway at 10.1.1.1 it says:
From 10.1.1.3 Destination Host Unreachable
I've tried the below that I've read elsewhere (eg. https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1576215) is meant to fix this problem:
sudo service network-manager restart
But this doesn't fix the problem and I cannot use the wireless network.
Updated with more information
Based on initial comments

I haven't tried the
modprobe suggestion in a comment as it sounds permanent. I will do a bit of reading first.
Doesn't this seem odd:
$ iwconfig lo no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"starkiller24" Mode:Managed Frequency:2.417 GHz Access Point: xx:xx:xx:xx:xx:xx Bit Rate=144.4 Mb/s Tx-Power=22 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:on Link Quality=70/70 Signal level=-29 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:42 Missed beacon:0 eth0 no wireless extensions. $ sudo ifup wlan0 Unknown interface wlan0
Would creating an interface in
/etc/network/interfaces.d help? And if so why hasn't one been created?
