RBR850 WiFi speed
Can anyone tell me the max link speed for the RBR850? I have just got a new router from my isp (Zyxel ex5601) so I have been having look at it, I am currently getting an aggregated link speed 12...

According to the Product Data Sheet, the maximum theoretical Link Rate on the 5G WiFi band is 2400Mbps
This would be with the WiFi device (literally) within inches of the router. WiFi Link Rate falls off dramatically with distance and material between the router and device. (p.s. I have no idea what Dim Bulb thought to list the aggregate speed (2400 + 2400 + 1200) backward from the radio list (1, 2, 3). It is glaringly obvious that the 2.4G radio is the one that has a theoretical maximum of 1200Mbps)
If the laptop is connecting to both WiFi routers at 5G and the same relative distance, I have no explanation why one would be twice the Link Rate of the other.
Note also that Link Rate is not the same as Internet Speed. If the Orbi WAN port (2.5G) is connected to the Zyxel 2.5G LAN port, then measured internet speed should be similar when connected to either router.
