@yay77 Hi, I am out of suggestions and maybe it is a bug for VR600. You could contact their technical support for more advice. https://www.tp-link.com/support/contact-technical-support/

@Winnie-1953 I think the Chipset of Deco M5 and M9+ limits them from supporting WiFi 6/7. The first Deco-POE model, Deco X50-POE has a flat shape and supports mounting. Maybe you could check this...

@matiheilen There are some recommended suggestions: Q9: Why is the audio quality so terrible? https://www.tp-link.com/en/support/faq/2316/

@JohnTait You could have a look at Q6 Why my PC can’t find my Bluetooth devices after the Bluetooth USB Adapter is installed successfully? https://www.tp-link.com/en/support/faq/2316/

@MomoBB I think it is asking for your wireless password.

@Janath I tried it before and it still works, but the connection sometimes is intermittent and the speed suffers as well. It works better without the surge protector.
