after some serious digging I finally realised that the problem with setting up my Ubuntu server via wifi is not working because wlan0 is not configured but it turns out that wlp18s0b1 is!? When I run iwconfig wlp18s0b1
I get the following:
IEEE 802.11bgn ESSID:off/any
Mode: Managed Access Point: Not Associated Tx-Power=0 dBm
Retry short limit: 7 RTS thr: off Fragment thr: off
Encryption key: off
Power Management: on
How then can I set my ESSID?
Thanks!
