Abstract:

Ubuntu detects wireless interface, but menu does not show any wireless network.

Details:

I have installed Ubuntu on MacBook pro early 2015. The appropriate drivers for my wifi are installed (according to this question WIfi Issues with Macbook Pro Retina Early 2015 (12,2) on Ubuntu 15.04). My device is

~$lspci -nn | grep 0280
03:00.0 Network controller [0280]: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 01)

and it seems, that Ubuntu sees wireless interface

~$ sudo lshw -C Network
*-network

   resources: irq:19 memory:cda00000-cda0ffff memory:cda10000-cda1ffff memory:c1a00000-c1a0ffff

Therefore I do not get, why the menu with possible connection does not show any wireless networks (only Ethernet cable). I also installed next to unity KDE, and in the both cases, the list is blanc.

I also tried to install what is recommended here, Ubuntu can't detect wifi networks on macbookpro 13.3 but without any change of output (it is different wifi if I understood right, not wonder it has not worked).

I reinstalled OS and then this solution https://askubuntu.com/a/624746/492421 have worked. I am sorry, but my question is a duplicate.

Connect to the internet using LAN/Phone USB tethering. Then issue the following commands.

sudo apt install b43-fwcutter firmware-b43legacy-installer
sudo modprobe brcmfmac
sudo modprobe brcmutil
sudo modprobe brcmsmac
