FINAL UPDATE W/ SOLUTION: It hadn’t dawned on me that my wifi extender could have been creating issues, until I realized that it was only pushing my guest SSID to devices at the far end of my home and outside. I literally unplugged it and all my IOT devices connected and have stayed connected! So, not a router issue, but the damn wifi extender! Thanks to everyone who gave their suggestions.

Details:

I’ve got a TP-Link AX5400 Wi-Fi 6 Router router set up with 2.4ghz, 5ghz primary SSID’s and a 2.4ghz guest network for my IOT devices. This has been the setup for a very long time, and I’ve got around 30 IOT devices connected to this guest network at any given time.

Last night, I noticed my doorbell cam wasn’t connected. After many failed attempts, it seems to ONLY want to connect to my normal 2.4ghz SSID and refuses to connect to the guest network. Even worse, the majority of my other IOT devices (wifi cameras, wifi thermometer, weather station, etc.) aren’t connecting to the guest network anymore, and I really (REALLLYYYY!) don’t want to have to re-pair them to my network (most are outdoors, and not easy to access).

At one point, a bunch of them were connected and I could livestream from nearly all my Reolink wifi cameras, but then they dropped connection and only one seems to still be working…

There have been no changed to my router, no new firmware, no settings changed, and no internet issues over the last many days/weeks, so this truly seems to have happened out of the blue.

Router reset has done nothing.

Anyone have any idea why they would refuse to connect to the guest network?

UPDATE: Several hours later and a few devices have come back online (on the guest network). Some are connecting and disconnecting still, but most are staying connected. I’ll probably end up manually re-pairing the bunch which aren’t automatically connecting and call it a day. Still not sure what caused this, but I really hope that’s the end of it, or else I’ll go to wired everything. LOL

    Yes, I did that early on as I thought there could be some conflict there, but I’ve got both bands on optimal channels and ruled that out.
