5G not stable and impacting wifi network and restarts
Hello ,
I have upgraded from LTE 4G router to 5G router Archer NX200 however since that time I'm suffering big time from instability of internet connection and wifi clients keep being unable to access the network .
When the issue happens all wifi clients gets kicked out from the network , I have to plug device to router's direct LAN and udpate channel from 11 to Auto or vise versa , which makes client able to login to network again.
Another symptom of the issue that internet suddenly get "disconnected" mode and shows message to configure DNS manually , most of the time this get followed by automatic restarts by the router. Nevertheless, I have to manually restarts it and make the change in wireless and save to get access again.
TP-Link support is not helping , i have an active ticket and no resolution is provided till now !!
I was able to get the logs towards external rsyslog system , below logs in red shows the time just before the wifi client got kicked out , mac address were modified for privacy

Hello ,
Thanks for the provided release , it definitely enhanced stability. However, still I have two observations:
1- I still have to keep my router in manual band search as below , otherwise network will be distributed.
2- in case of unexpected power interruption and router restarts , Apple-based devices does not get stable wifi until I forcefully change the wifi band and save

Hi,
I too face issue similar to you and other issue (multiple) on KSA STC network, has been working with support and still being worked.
Have you tested NX200 stablity in manual band = N77 vs other bands.
I see network stack stability which is triggering modem reset or network resets.
