Unable to connect with the hotspot created on ubuntu (2025)

What got things working for me was the disablement of Protected Management Frames

nmcli c modify Hotspot 802-11-wireless-security.pmf 1

This seems to be an issue with wpa_supplicant version 2.10+ ([1], [2]). You can either use hostapd to create a software AP manually by first masking NetworkManager for the Wifi device [3] and then following the instructions linked in the same article---or try using a different security protocol such as WPA3/SAE. The latter can be achieved using:

nmcli connection down Hotspotnmcli connection modify Hotspot 802-11-wireless-security.key-mgmt saenmcli connection up Hotspot

Take care not to use the GUI to activate the hotspot as this will reset the settings.

Switching to WPA3 solved the problem in my case and works as long as your client devices support this protocol.

• This worked for me, after the Linux mint 21 version update hotspot with the password suddenly stopped working. Thank you!!!

This looks like the bug raised for Ubuntu 20.04 - Can't connect to hotspot created on ubuntu

Posting this as an answer as I don't have enough reputation for comment.

Do this using the network-manager

Install it first if you don't have it :

sudo apt-get install network-manager

Then

1. Search for network manager in your Desktop environment,
2. Create a new connection, select wifi.
3. In the WIFI tab go to Mode and change it to Hotspot.
4. Choose your network interface e.g wlo1 in the device option,
5. Then go to IPv4 choose Shared to other.. in the Method option,
6. Add normal security WPA/WPA2 Personal with simple password

• This didn't worked.

• @sawankt The plus sign on your wifi SSID is for an android feature called Wifi calling You can disable that from the settings, depending on your android version,try to disable that feature, delete the network profile in your phone and reconnect to Ubuntu. Wifi calling is way to make calls using WAN using the internet communication and not normal antennas.

I have the same issue on Ubuntu 23.10 with KDE. The hotspot works well if I set no password and I could not connect as long as I set any password.

I see the solution in a good reference https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/104

So, basically what you need to do is to create a hotspot connection first, and name it, for example, ad myhotspot and set the password in the GUI. Then you can turn it off by

nmcli connection down myhotspot

and then config it by

nmcli connection modify myhotspot wifi-sec.pmf disable

and then turn it on again

nmcli connection up myhotspot

Hope this helps.

This is the most accurate code that can solve your problem

`

1. nmcli connection down Hotspot
2. nmcli connection modify Hotspot wifi-sec.pmf disable
3. nmcli connection up Hotspot

• Open the system menu from the right side of the top bar.

• Select Wi-Fi Not Connected or the name of the wireless network to which you are already connected. The Wi-Fi section of the menu will expand.
• Click Wi-Fi Settings.
• Press the menu button in the window's top-right corner and select Turn On Wi-Fi Hotspot….

Note: If you are already connected to a wireless network, you will be asked if you want to disconnect from that network. A single wireless adapter can connect to or create only one network at a time. Click Turn On to confirm.

You can also connect to the wireless network by scanning the QR Code on your phone or tablet using the built-in camera app or a QR code scanner.

• This dosen't answer my question

When I open GNOME settings to the WiFi page, the "create hotspot" option is initially greyed out. Switching to any other settings page and coming straight back makes the option available. Similarly, if I first open GNOME Settings to a different page (ie. bluetooth from the shell top right menu), and thereafter navigate to the WiFi pane, then the option is available.Steps to reproduce:

Solution:

1. Open GNOME Settings
2. Try to activate hotspot, it is greyed out
3. Switch to "Network" or "Bluetooth" or "Background" setting page
4. Back to WiFi "Activate hotpot" menu option is available

For me, I go to Edit Connections... and under Wi-Fi Security choose option Enhanced Open. It is a new Wifi protocol that does not require passwords but is still secure.

The WPA & WPA2 Personal option used to work for me, but after an upgrade it no longer works. Anyway, the above setting works for me now.

For me, I used the following commands:

$ nmcli device statusDEVICE TYPE STATE wlp1s0 wifi connectedenp0s31f6 ethernet connected

Now add the following lines:

$ echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward$ sudo iptables -t nat -A POSTROUTING -o enp0s31f6 -j MASQUERADE$ sudo iptables -A FORWARD -i wlp1s0 -o enp0s31f6 -j ACCEPT$ sudo iptables -A FORWARD -i enp0s31f6 -o wlp1s0 -m state --state RELATED,ESTABLISHED -j ACCEPT
