This is some trouble I faced. When I create a wifi hotspot from my laptop, I couldn't connect my phone to it.
Normally it allows when you create an open wifi hotspot, but with a password protected one you can't.
This is because Ubuntu based OS's create ad hoc wifi networks, and they are not compatible with connecting to other devices. We can fix this with a simple trick.
1. Create a new wifi connection
This is nothing big, most of the Ubuntu based OS's have a GUI to do this via a network icon the top etc.
Remember create it as WPA & WPA2 Personal network. This is the type of the network that we're gonna create, and it allows you to set a password for that.
2. Make it accessible to other devices
After you creating the wifi network it will create a file in the /etc/NetworkManager/system-connections/ directory
I created mine as mynetwork so here is the file I got. You might need sudo permission to access that.
The file is there, so I just wanna edit it so i'd open it up with my favorite text editor, and edit the line which has the attribute mode..
I'm using gedit to show here, but i'd rather use vi.
$sudo gedit /etc/NetworkManager/system-connections/mynetwork
It'll open up the the file in the text editor. Find the line for the mode.
Replace the value adhoc with ap

Save it and close out the text editor.
3. Start the wifi hotspot again and it'll be available for your android device!
