http://smallbusiness.chron.com/resolving-local-ubuntu-38861.html

Open for edit:
sudo gedit /etc/avahi/avahi-daemon.conf

Uncomment and change the value:
BEFORE
#domain-name=local

AFTER
domain-name=.alocal

If this did not fix the issue, add this line at the end of the file:

AVAHI_DAEMON_DETECT_LOCAL=0 

Save the changes and exit. 

What to do if Wi-Fi on Linux Ubuntu 14.04 does not work

In any case you will need to download two packages from the internet. How to do it if you still don't have the access? ))

 

Lets suppose that you have at least your mobile that is online. If so try to connect your mobile phone (in my case Samsung Galaxy SII) to Ubuntu by USB. Make sure Ubuntu could recognize your phone and let you see its internal folders. Thus, when you will be asked to download files by instruction given to you in the link below, download it first to your phone (e.g. into Download folder), then copy them to the Home directory of your Ubuntu.

So follow this instruction below:
