This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

here is a clear guide to create a Wi-Fi hotspot detectable by any Android phone on a Ubuntu 14.04 using the Network Manager and a minor hack:

  1. Click on Network manager -> Create new Wi-Fi network
  2. sudo nano the newly created file /etc/NetworkManager/system-connections/yourWifiNetworkName
  3. change the mode line to: mode=ap

Thats all! From now on you can enable this network from Network manager -> Create new Wi-Fi network -> Connection: select yourWifiNetworkName from the dropdown

By default Android cannot connect to ad-hoc wireless networks (regardless of whether you are using Windows, Linux, Mac etc.)

There are third party apps (as mentioned) that you can install on your Android device but they might not be compatible, have problems or require you to root your handset.

You need to find out how to turn your wireless into an infrastructure type network for your phone to be able to connect.

Important is the

 Method: shared to other computers

in ipv4 settings which is bridging the wifi to the existing internet connected network. This permits the DHCP requests from the Android to succeed.

This works pretty much out of the box in ubuntu 16.04. Restarting the network manager

   service network-manager restart

might be required though

As some people has said that default creation of hotspot is not able to get it in use with android or any other OS.

So you have to use it another way.

first go to edit connections from task bar and add new connection in WiFi section.

Remember to use security with wpa & wpa2 personal method. Also in genral tab, tick option that all users may connect to this network.

ssid = any name of your choice (e.g. Myhotspot)

mode : hotspot

band : Automatic

channel: default

Device: select your wireless adapter from drop down menu.

Leave ipv4 and ipv6 settings. and save the setting.

Then from taskbar to start the hotspot,click on create new WiFi network
and then in connection select hotspot and click on create. now you can use it in any device.

NOTE: dont turn on hotspot from network setting (From use as hotspot)

This method is for Ubuntu unity desktop version
