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.
