Enabling Guest WIFI knocks out other 2.4 home SSID
I'm trying to set up the Guest WIFI SSID. The guest SSID is on 2.4 GHz. When I enable it, I lose access to my other 2.5 GHz SSID. The name shows up on available networks, but when I try to log into it, it tells me there was an error. I can log on to the guest network no problem, when it's enabled, but it seems to be either or. Any idea what I should look for to fix this?

We want to help figure out what's going on with your Wi-Fi networks, mechleon!
We recommend downloading the Smart Home Manager app to manage your networks. It's an easy way to personalize and manage your home network info from your device.
Quick question: Are you using a third party router behind your AT&T equipment? Knowing this will help us to determine what steps we need to take moving forward.
We look forward to hearing back from you!

I figured it out. When I enabled the guest network (I was doing this through ATT gateway 192.168.1.254), I also decreased the number of allowed connections to my home LAN network. I did this for security because I plan to use the walled-off guest network for IoT devices. However, because I hadn't yet changed the network for my devices, they grabbed all the available connections to the home network and so my phone and computer etc could only use the guest network. It looked like my home network was knocked out, but in fact it was only full up. Once I raised the number of connections possible to the home network the problem disappeared. Now that I've moved all my IoTs to the guest network, I can, for security, reduce the allowed connections to my LAN. What fun!
