Question about TP-Link Deco X60 (3-pack)

No it uses triband but it is all WiFi. One could use Ethernet cables as a backhaul, but the main focus here is the WiFi6 mesh. The only ones that used powerline as backhaul are the Deco P7 or P9. All have HomeCare in common, the free antivirus and antimalware solution that is integrated into the router. It protects every device that is connected to these Deco units.
