I recently installed LTS 16.04 as a dual boot with my windows 7. Post installation i am unable to connect to my home wifi. The broadcom driver is installed and working. The wifi connection works as expected on the Windows OS and on the ubuntu i am able to connect to the same home wifi if i tether it via my mobile phone. Also i am able to see my neighbours wifi in the list and a whole bunch of other networks except my home's network .Has anyone faced this issue.. any help would be great.

  • Did you try "connect to hidden wi-fi network"? under the wireless icon? Your router may not be broadcasting its ESSID. – ubfan1 Oct 18 '16 at 20:27
  • @AndroidDev Yes, I will help you with a VTC! – chili555 Oct 18 '16 at 20:31
  • If your home wifi is on a 2.4Ghz channel higher than 11, the broadcom modules don't allow it. The channel.c file of the brcmsmac source code is full of regulatory checks. I would report a bug against package linux at https://bugs.launchpad.net/ubuntu if you are in a country where channels higher than 11 are allowed and you cannot access them – Jeremy31 Oct 18 '16 at 21:09
