"...Netgear stands alone with its use of a dedicated backhaul connection between router and satellites. In short, this is a second 5GHz, 1.7Gb/s radio band reserved specifically to relay data between the units so, unlike any rival, this data is not competing for space on the WiFi network with the rest of your connected devices.
The result is not just increased speed, but (spoiler) a more stable connection between the units which results in significantly faster coverage around the home. In conjunction with WiFi 6, it’s a killer combination. "
