Wrong IPs being given out
I have a SXR80 modem as well as a SXS80 satellite mesh system. Everything was working fine until a slight power outage happened and all of my IoT devices restarted. Of my 30 light switches, 3 conne...

One tactic might be:
- disable the IoT network
- power the router and satellite off
- boot up only the router.
- let the network stabilize and verify that none of the IoT devices have connected.
- enable the IoT network
My goodness, what a mess!
I tried this last night. No luck. After turning everything back on and getting the IoT network back up, the 192.168.1.80 devices came back. I've tried every different combination of disabling network, disabling DHCP, removing IP addresses from the pool...you name it, no luck. For fun I decided to try to add my cell phone to this network. It tried for a little bit and then failed with the error "unable to get an IP from the server". I tried to add my laptop as well, it got an IPv6 address, but no actual IPv4 (169.254.89.58 with a subnet of 255.255.0.0). Not sure if that helps anything.

This indicates that the laptop failed to get an IP address from the network. 169.254 IP addresses are known as Link Local addresses, created by the laptop itself. (both the IPv4 and IPv6 addresses) Nothing came from a DHCP server.

Correct, which would indicate there is a problem with DHCP server. Which in this case is the Orbi.
How is the laptop connected (wired? WiFi?)
Are all of the LANs affected?

The laptop was Wireless, as was the phone. Only the IOT LAN (LAN3 - 192.168.30.xxx) is having this problem. I can connect to the LAN1 wifi without a problem. It gets an IP address and connects to the network. I can also connect to the Guest LAN (LAN4 192.168.40.xxx) without a problem.
