Hello @lumos123 ,

Welcome to our community.

 

May I confirm the model number, hardware, and firmware versions of your device? Please refer to

How to find the model number of your TP-Link device

How to find the hardware and firmware version of my TP-Link device

 

Please provide your complete topology. For example:

ISP modem—BE3600)))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

 

Have you changed the settings recently? Like the firmware update, or adding a new device to the network?

How about the wired connection? Is it stable?
