Debian

Wireless adapter is intel so android client didn't connect to ubuntu hotspot. Ubuntu is failed so I want to install debian or suse on notebook for hotspot. Which one is the best for hotspot.

How are you connecting your notebook to the internet?

A great deal of what are referred to as "hotspots" use 3G or 4G wireless connections to cell towers and 802.11 wifi for clients to connect.

if you're plugging in with an ethernet cable, you should have the necessary hardware to connect at least one wifi client, but either way, I don't know whether any current release Linux distribution has a simple turnkey setup for this. I'd wager Ubuntu would have it as easy as anyone, but I would probably check the Ubuntu forums. If you're trying to connect to the internet and serve as a wifi hotspot with your one built-in adapter, it's just not going to work for you, as far as I am aware.
