@InderDhindsa Hi, No it is not acceptable and the backhaul only works when Deco units are under the same Mesh network.

@Hispanico Hi, I think two more Deco X20s should be enough. And if you are looking for a higher model, maybe you could have a look at the tri-band backhaul Mesh, like Deco X50/X55.

@IYS Deco XE75 has 6 GHz: 2402 Mbps (802.11ax) 5 GHz: 2402 Mbps (802.11ax) 2.4 GHz: 574 Mbps (802.11ax) Normally, 6ghz is for the devices that are capable of WiFi 6e If your devices are WiFi 4/5/6,...

@tplank It should be ok to access the ISP modem's web UI when you are on Deco's Wi-Fi.

@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...
