Devices suddenly fail to connect to flint 2

hi, today a problem occurred that was impossible for me to solve, when I restarted the flint 2 router with LUCI all my devices could not connect anymore, as regards the lan networks I had to manually set the sub net ip dns data (on one pc there was a dhcp problem), while for the wifi the connected devices work halfway, everything worked perfectly before the restart

Let's start by taking a look at your config to see if we can spot any problems:

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

It appears you are using firmware that is not from the official OpenWrt project.

When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.

You may find that the best options are:

  1. Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
  2. Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
  3. Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).

If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.

I downloaded the beta version on the official website GL-MT6000 Flint 2, I don't understand, but it worked fine until now, could it be because a new beta version has come out that is giving me problems?

Maybe... but that's not from the OpenWrt project... it's from GL-inet, so you'll have to ask them.
