This simple tutorial shows how to enable Wi-Fi hotspot in Ubuntu 22.04 and configure bandwidth (2.4/5GB), security type, etc.
First of all, you have to make sure that:
- Your PC/laptop has connected to internet.
- A Wi-Fi adapter is free for access point.
A laptop usually has only one wireless card, so you have to connect a wired network.
Enable Wi-Fi HotSpot
Firstly, open Gnome-control-center (aka Settings) from upper right corner system menu.
In the first Wi-Fi page, make sure you have turned on the switch in header bar. Then click on the tree dots ‘⁝‘ icon, and select ‘Turn on Wi-Fi HotSpot‘ menu option.
In the next pop-up dialog, just type a password for authentication when trying to connect this hostspot.
Once you click ‘Turn on’, the Wi-Fi settings page should display QR code that mobile device can scan to connect. As well, it displays the network name, security type (WPA & WPA2 Personal by default) and the password.
Configure more about the hotspot:
The default settings are usually OK. But, if you want, there are more options for the access point.
Firstly, press Windows (Super) key on keyboard to open the overview screen. Then search for and open “Advanced network configuration”.
When the utility opens, select “HotSpot” in the list and click on the gear button to configure it.
In next pop-up dialog, you’ll see the options to configure SSID, Bandwidth (2.4GHz/5GHz), channel, speed limit, etc.
If you’re not OK with default security type, go to ‘Wi-Fi Security’ tab and select another one. There are also automatic connect, proxy, IPv4/IPv6 settings, see the screenshots below for details:
