A:Answer As I understand, either could be set up as an access point to the other, but separate SSID would be needed for each band. I used my old router as a switch to help keep wired connections that I already had, especially since each Velop unit has only two Ethernet ports. Just turn off DHCP, and make sure the old router IP address does not conflict with Velop units. Having just one SSID is wonderful after having to use a dual band router with a dual band access point. Having four SSID names all over the house was a hassle.
