I have a Netgear R8500, synology ds918, and netgear S3300-28X-PoE+, and 40 other devices (control4 with multiple controllers for c4, ip cameras, Nvidia shields, thermostats, garage doors, etc)

I was having issues (couldn’t get devices to connect at all on any band and wasn’t using over 120 devices at a time). I tried rebooting my router but it didn’t work and even froze one time. I updated firmware before I realized I had my DHCP only allowing new devices to connect to only over .100; prior to wiz I had static ips set for all devices permanentl devices. I tried to add as many wiz lights to static and netgear capped that at 80 devices. I fixed the DHCP but still having major issues connecting to wifi.

I do have connectivity issues in different rooms, esp 5ghz in my two level house, (over 4500 sqf.)

Would just upgrading my router to say Orbi Pro WiFi 6 be a fix all? Should I upgrade and use r8500 for separate network just for wiz devices? Make a subnet?

Not sure if this is necessary, but thoughy an ideal might be to have all my electronics (wiz lights ecobee thermostats, echos, control4 etc) on one network that don’t require more than 2.4ghz; ip cameras and nas on one if beneficial; and one for streaming devices, smartphones and computers.

Hope this isn’t confusing or ridiculous.
