Hello, thank you for asking the community.

Do you mean the wired connection and 5G connection are still working just fine after the firmware update, only the 2.4G network gives an issue? What are the devices that need to connect to the 2.4G network? Are all of them experiencing the same disconnect at the same time?

Try choosing the wireless mode to 802.11a/n/ac mixed instead of 802.11 a/n/ac/ax mixed, then monitor again. Also, you can choose the 2.4G wireless security to WPA2-PSK, AES.

Hi @Kevin_Z, thank you for quick reply.

 

Yes, the 5Ghz connections are working fine. Only 2.4Ghz connections are affected by the issue. All my smart home devices needs to connect to 2.4Ghz network, it includes: door locks, lights, LED strips, smart plugs, etc. They only work with 2.4Ghz frequency. And yes, they connect just fine, but suddenly they all gets disconnected at same time, if I look at client list in router it shows connected devices in LAN, 5G, but not a single device in 2.4Ghz. Even the devices that work fine with 5G, can not remain connected if I connect they to 2.4G network.

 

I already switched mode to 802.11a/n/ac mixed and security protocol to WPA2-PSK[AES] with no success. Since I work with IT, I've passed the last three days playing with every possible combination of wireless configs expecting a workaround to remain until a new firmware release. The problem is, this issue don't have a pattern, it can occur in hours, sometimes it occured in minutes. This is driving me crazy.

Hello @thewerthon, thank you for getting back with all the details. Please don't worry, the new official firmware is a stable one and it has been officially released, the website update may get delayed. You can check that later.

To figure out the issue you are encountering efficiently, I've forwarded your case to the TP-Link support team who will contact you with your registered email address later. Please pay attention to your email box for follow-up.

I am also experiencing this issue of 2.4Ghz stops working occasionally, which is fixed by restarting the router,
or in fact by changing any wireless-related setting and saving, which causes the wireless module to restart.

 

I also recently updated the firmware of my router, though in my case the new firmware version is 1.1.0 Build 20211125 rel.59476(4555)

(Hardware Version: Archer AX73 v1.0), and when I check for updates it says "Firmware is up to date".

 

My last attempt was to disable OFDMA and TWT, but I only did it this morning, so I still don't know whether it will help, as this issue occurs only once every 1-3 days or so.

5Ghz connections continues working normally (I gave it a different SSID), and wired probably also but I didn't check.

Here are all my current settings for 2.4Ghz:

Hello @Beorn, yours seems different from what thewerthon was reporting, but you can also try my previous suggestion that changing the wireless security to WPA2-PSK, AES, then reboot the router and monitor.

BTW, what are the devices connected to the 2.4G network? Are they working fine before? Please check again if you can detect the new official firmware on the router web GUI or via the Tether app.

Hi @Kevin_Z, thanks for your suggestions.
I tried changing the settings yesterday morning, and it works normally since then. I will let you know if the problem starts again.

I also tried checking for updates again, but I don't get any newer versions shown.

 

My 2.4Ghz devices are also mostly smart home devices (such as Shelly Relays and others), they all work normally,

and when the problem starts all of the 2.4Ghz connections drop from the connected clients list (about 16 devices), with only 5Ghz devices remaining.
I currently don't have any devices connected via LAN, so I can't tell for sure if this one keeps working or not.

 

Thank you for the update @Beorn. I hope the connection will be stable now. But please let me know if it's not.
