Today I received an Archer BE550 router. Sadly I've had to return the device due to the restricted capability of the DHCP Server. For some unknown reason TP-Link have restricted the ability of the DHCP to  192.168.0.*. This severely limits the device. There seems to be no need for this restriction. The Firmware needs to be updated to support the full range of options  10.x.x.x, 172.16.x.x, 192.168.x.x . Please be aware of this restriction if you planning to buy this device.
