Hello 

 

after long investigation in wifi interruption and instability with TP-link Archer NX200 , it is found that behavior from TAPO Hubs shown below exahsting the router and DHCPD and all existing wifi client got kicked out and can no longer join the wifi . quick remedy was to update wifi "channel" and save forcing something to reset . 

 

after thorough investigation I found that hubs are the root cause of that overloading , mac address E4:99:77:77:66:66 and E4:11:44:44:55:55 are TAPO H200 hubs connecting thorugh wifi (mac address were changed for privacy )

 

 

The way I overcome the issue was to assign local IP based on mac-address , wifi become stable.
