Intermittent DNS Errors and WiFi Issues

RBR750 here - This Furry guy also commented on my post about this, also without anything useful.  I've tried everything that I can do fix DNS on the Orbi.  The stupid thing just resets the DNS proxy (indeed it's a no-caching passthrough with a single purpose - to serve up a made up domain name for you to login easily).  It's only other purpose is to crash.

For Windows machines, you can fix this by bypassing the DNS proxy, but for IOT devices, you're SOL. 

I went to set up a pi-hole to server DHCP and DNS yesterday, and realized that I wouldn't be able to provide the IP separation for my guest and internal networks with a single solution (I'll need one pi-hole per SSID).

It sucks that I have to set up a complex network to solve the ever-crashing dnsmasq on a router I spent hundreds of dollars on, and that Netgear won't fix it....all we get are posts of 'did you try this, did you try that'.  There are plenty of posts on these boards that talk about how DNS constantly fails on these machines, and everyone working around it in different ways... including just turning off the router and using the Orbi as an AP, which is stupid - if I wanted AP's, I'd have bought them.

Of course, I'm now past my 90 day mark - so I'm not going to shell out MORE MONEY to Netgear to get support so they can just ship me another non-working (broken firmware) device.  And now that they've turned off telnet, I can either invalidate my warranty with alternate firmware, or solve the problem with alternate DHCP/DNS servers...

As much as FURRYe38 wants to believe it's some configuration error, anyone with any TCP/IP, DNS or server knowledge can tell you that the dnsmasq service on the device is crap and is broken in its current configuration....
