I think that could be a problem with some interface or something else. It works properly from any other devices (iPhones, mac) but the only problem is with my Dell with Ubuntu 20.04.

I don't know if it is related but every time I tried to connect to wifi other devices lost connection for a couple of minutes. It looks like my attempt restarts the wifi adapter. The same thing happened when I tried wired connection.

Thank you for any suggestion.

The added information about how other devices can connect to the wireless access point however your (Dell) with Ubuntu cannot was very helpful. This could be because of a couple reasons however: One could be that the Channel is in heavy use for the Network you want to connect on, the other would be faulty /etc/NetworkManager/NetworkManager.conf using (configured as) wpa-supplicant instead of iwd.


1. The SSID you are trying to connect to has too many users on that particular channel setup and there is interference from other wireless access points.

You can find this out by typing:
sudo nmcli dev wifi list

This will allow you to observe set channel of various networks and signal strength.

2. For whatever reason the Network-Manager on your setup could not do well with wpa-supplicant and instead needs iwd instead.

First install iwd with sudo apt-get update && sudo apt-get install iwd

then ensure connection to the service by
sudo systemctl enable iwd.service

sudo systemctl start iwd.service

Next open /etc/NetworkManager/NetworkManager.conf and add wifi.backend=iwd to the [DEVICES] section.
After a reboot this will yield a positive connection if all changes were saved. If not there could also be some Network-Manager parameter that needs to be modified in that same file that prevents connection.

  • Thanks for your reply. I will post the result later. – silhouette Feb 17 '21 at 13:27

    Upon further research into backend iwd service, it seems to have selectiveness when it comes to using a band. If the signal strength of 2.4GHz is stronger than 5GHz, then it will connect to 2.4GHz, maybe restart iwd.service with "sudo systemctl restart iwd" and boot again to connect to 5GHz.... at least step in right direction. It could also be the SSID or even BSSID addresses and how the back end selects the access point. – CraigslistCesium Feb 18 '21 at 03:55
  • I'm also interested in the config error in your updated answer... "No secrets" for the 5GHz. [config -> failed (reason 'no-secrets', sys-iface-state: 'managed')] Could it be possible that you are using open WIFI or the same password applies for both bands? There is a program you can use with network manager to interact with set connections called "nmtui", could you possibly reset the connection from there? You can edit automatic connections with nmtui. – CraigslistCesium Feb 18 '21 at 04:21

We fixed the issue by half. Now, I am able to connect to wifi via 2G network, but 5G network still doesn't work.

The same issue with restarting wifi adapter (wifi networks 2G, 5G are unavailable for a couple of minutes) when plugin ethernet or try 5G network.

I think it's no problem with high traffic, as well. I tested the issue during the night when nobody has been connected and it is our home network.

There is log after succesfull connect to 2G and attempt for switch to 5G.

I've had a similar problem with a cloned Mint 20.3 machine. It disconnects from the wifi when it's inactive for 10 minutes or so. I had changed the hostname and the ssh keys, but changing the machine-id seemed to resolve the problem. It's described here: http://ichimusai.org/after-cloning-a-ubuntu-22-04-server/

sudo rm /etc/machine-id 
sudo systemd-machine-id-setup
