TP-Link issues resolved (kind of)

[Steve Henley]

If the Kasa TP-Link device you are trying to configure is the KP303 - Kasa Smart Wi-Fi Power Strip, 3-Outlets, I had a look at the configuration info, and this does not bring me joy.

I would definitely keep that device in a DMZ. If you have other Internet Of Things gadgets to connect, before doing anything else to the network configuration I would look at all of my network devices and see what can connect wired vs wireless, and what devices I would want to keep in a DMZ.

I have had trouble with the Unifi AP getting updates via wifi and moved it to a wired connection to resolve that. I could use a wired connection on the same subnet as the wifi (192.168.1.0) I guess. I just ran out of ports and the Unifi USG that I have has an open port, so I used that one (but that USG port has to be on a separate subnet).
