The Deco X96 and Deco X76 Plus are both tri-band systems, and they’ll use the new 6GHz network as a backhaul to communicate between router notes.
There is one downside, though: when you eventually buy phones, laptops, and other devices that support 6GHz Wi-Fi connections, these systems will only connect to them over traditional (and likely slower) 2.4GHz and 5GHz networks since the 6GHz network is being used by the routers themselves.The Archer AX96 and Archer AX206 are both tri-band routers, but because they aren’t mesh systems, that 6GHz band is free to connect with individual devices.
