I replaced my WNR1000 NETGEAR Router with the ASUS LYRA VOICE AC2200.
But, if you have a multi-level space, you will need to add as many ASUS Range Extender nodes as required to take advantage of the AMAZON ALEXA LYRA VOICE enabled units. So, you would want to be able to use that feature wherever you are in the house to request music, weather, traffic, make Amazon searches and orders, to receive status reports on deliveries, etc. If you have a small space, you may only need the one unit.
