When picking a wireless router we suggest that you pick one that supports at least up to 1000 Mbps and 2.4 GHz and 5 GHz bands. Read carefully about the wireless router you are going to pick and check the range that it will support. In some cases with very large homes you may need to get a wireless mesh system to boost the connection throughout your home.
We have played with the following routers and happen to like them.
Google Nest WiFi
Netgear Orbi Mini
