Let's review the config to ensure there aren't any issues that might be causing this:

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

Thanks.
I already updated my topic with more information

This route looks wrong:

Where is 192.168.1.0/24?

Remove the cell density:

Don't use psk-mixed, select WPA2 (psk2) instead. Also, hiding your SSID doesn't improve security, so remove that option.

Restart and test again.

Thanks for your suggestion.
I will try it later.

Not work.
When I back my phone, it upload large data, the wifi crash very soon.
Only browser, it seams ok.

7

Do you have the same issue with 23.05?
The Phicomm k2g is an 8/64 device and we are very close to the end of support for that configuration.
I see that your Phicomm k2g is also a PPPoE client which is quite CPU and memory intensive.

NO，never happened with 23.05.
I notice this happened when I backup my phone data to server.
So upload large data will trigger this error.
Just browser web and watch video seams good.

I got the same problem.

After upgrade from 23.05.5 to the latest release,

https://downloads.openwrt.org/releases/24.10.0/targets/ramips/mt7621/openwrt-24.10.0-ramips-mt7621-d-team_newifi-d2-squashfs-sysupgrade.bin,

any heavy load use case will result in 5G wifi down and SSID disappear. Even just browsing and chatting, the problem will finally happen in arround 24 hrs, while 2G wifi and wire still accessible.

ssh command - wifi restart does no help. luci "wireless, restart" will return an error like "device not available". Only reboot will bring the 5G wifi back.

Since all settings are proven OK in 23.05.5 and as stable use in months, I have to roll back to it.

Could anyone know the reason? There are many changes with the new kernel.

Thanks
