My brand new C-8 bricks my LAN internet access

[ADiamond]

Thanks, guys, for all the great suggestions and support!

Now that things are roughly stable, I typically save off my router configuration after major modification. I don't take Netgear router updates anymore. (Netgear Tech Support actually followed my suggestion and now make router updates optional after they bricked my Orbi - and probably many others - due to their forced firmware update policy)

I will follow the suggestion to set the router address range to a /24 subnet, and I suspect a number of devices are going to end up unhappy for a few days. I have run into subnet issues in the past with my current /16 subnet and got things resolved, so I expect I'll face a few temporary issues when I go in the other direction.

Just make a note of all your devices and do a DHCP reservation for your IOT devices. Let everything else be random.

So larger ranges aren't determined by scopes. 192, 172, 10. Are pretty much reserved scopes for private use. What's determines scope is your subnet. So you can set your subnet to /24 (255.255.255.0) regardless of what the scope is 192.168.1.x is. Otherwise with a /16 you're flat networking 65000 ip's which can be ok but can cause problems with some iot devices. I would shrink your subnet down to /24 and if you need more than 256 network devices then simply vlan off using the next one up while still maintaining a /24 for that subnet

I love it when you talk dirty...

I actually gained some new networking info on this topic, very useful.

Seems to me @rlithgow1 should offer to drop by to troubleshoot.

If most of your devices use DHCP and are npt set locally on the device then they will pull the updated subnet the next time they renew from the Router. Worst case scenerio would be you just need to reboot such a device. This is why i generally set everything in my router vs local config.

This is the way.
