I bought a Netgate 4100 and am using my existing Netgear RAX42 router as an Access Point. I cannot segregate the guest network traffic from the main network traffic. The router firmware does not offer VLAN support in Access Point mode. There are no OpenWrt or DD-wrt firmware options for this router. I am willing to buy another device that offers WiFi6 with the same range and speed as my current router.
