Here are the network manager logs from one of the devices that fails to connect ( I have highlighted the failures ): I checked and the router logs don't show anything. When all the devices are disconnected from the internet, how about the internet LED on the AX1800, is it green or orange? If the internet light is orange, please connect one computer to the modem directly and confirm if the internet still works on it.ДЄdditionally, please send me the whole system log from when the internet gets disconnected, please don't reboot the router. When trying to reconnect, I see auth failures on the devices that are trying to connect. The 2.4 Ghz AP borks out and disconnects all devices. Devices on the 5GHz band of the tp-link router also continue to work fine. devices connected through ethernet continue to work fine. Sure, I am with AT&T and have their default modem. All other devices on the 5Ghz network remain fine and so do all the devices connected through may I know who is your ISP and what is the model number of your modem, please? When the problem occurs, all devices on the 2.4 Ghz network disconnect and fail to reconnect.

With a couple other devices on the ethernet connected to the AT&T modem directly with the AX1800. Is the network diagram like AT&T modem-AX1800-Wired devices, 2.4G wireless devices, and 5G wireless devices?Д¬orrect. It seems to be a bug that causes connectivity issues after about 24 hours or stagnent use. I kind of mitigated the issue by setting the WPA setting to AES instead of the default TKIP/AES. It seems the router fails to offer an appropriate handshake. I did try factory reseting but the problem comes back after about 24 hours of use.ДЄfter a lot of trials, I think I found the bug.

What is the firmware of the router and when did you purchase it? Have you tried to reset it to the factory defaults and reconfigure it? If not yet, please give it a shot and see if it changes anything.ДЇirmware is 20200326-rel63914 purchased on June 1st 2020. 9 or so to the 2.4 Ghz network and 6 or so the 5Ghz network. May I confirm again how many wireless devices are connected to the 2.4G network and what are they? Are all of them getting disconnected from the network and unable to connect back? How about the 2.4G signal strength when you try to connect back on those devices?ДЄbout 15 in total.
