IoT network not DHCPing anymore

Let me preface this by saying I live in Texas, where our power grid goes down as often as the sun does. With that being said, last night there was a strong gust of wind that knocked out my power for about 10 seconds. My AT&T modem, Orbi router, and network switch are all on UPSs (because the power goes out THAT much) stayed online with no problem. All of my smart switches (mostly Kasa HS200) dropped offline and haven't been able to reconnect yet. All of my echo devices have dropped off line as well. I cannot get them reconnected to the IoT network no matter what I try.

 

When I try to connect my echo show to the IoT network (VLAN3), it says it cannot get a DHCP address. When I try to connect my phone to that network, I get the same-ish error (error is "cannot get an IP address"). If I switch my phone and echo show to the main network (VLAN1) they both connect with no problems.

I have tried turn of DHCP for that VLAN, as well as turning all DHCP off for all VLANs. I've even unplugged the router, modem, and satellite for 10 minutes with the same error coming up once everything is back online.. I've noticed that in the UI all of my switches are pulling a 192.168.1.80 IP address. All of them. VLAN3 should be 192.168.30.xx range. My two Nest thermostats are pulling 169.254.xxx.xxx IPs as well, so I know DHCP isn't kicking in at all.

 

Any thoughts of what else I should try, short of resetting to factory defaults?
