Connecting 2.4GHz device with BGW-210 700 router

I want to connect a 2.4 GHz device (remote thermometer) and it is not able to connect. I've tried dozens of times. I've read posts here, and some seem to say that band steering will handle this. Others say to separate the bands (does that mean band steering is then turned off?) I've also read of people having trouble after separating the bands. What options do I have that will allow this device to connect?

Have you tried to connect it to the Guest Network (which is 2.4GHz)?

No, I haven't tried connecting to guest. Does it need to be enabled to make it visible to my device?

There should be a setting in the 210 to enable the Guest network. I use my own equipment with another provider but I imagine that the AT&T gateway is similar. Some have even assigned a different SSID/pw to the Guest Network separate from the gateway SSID/pw and then pointed their 2.4GHz devices to that.

To enable the Guest Wifi route, go to http://192.168.1.254/cgi-bin/wconfig_unified.ha

Enter the Access Code as shown on the gateway's label.

Enable the Guest SSID and note the name and password because they are different. Don't forget to click Save.

Thank you all for quick and helpful responses. I was able to navigate through the AT&T website to turn on the Guest access and then connect the app and remote thermometer using that. Hurrah!!! Is there a reason why I would not want to leave Guest enabled? Will it interfere with running of my other devices on the 5G? Thanks again to all.

There is no reason to not have it on at any time, and it wouldn't interfere with any of your other devices.

Thank you for choosing AT&T. We appreciate your business.

@keg403  If you disable the Guest Network, which is what your thermostat is connected to, then the thermostat may not connect again. The gateway's broadcast in the 2.4GHz and 5GHz bands, and robust gateways can determine when the devices connect to it which band they are supposed to use. AT&T gateways seem to have issues with that in a lot of cases so enabling the Guest Network, which is always 2.4GHz and pointing your 2.4GHz devices to that is the way to go. That will not affect devices that connect to the 5GHz band. And, if you've assigned a separate SSID and password the the Guest Network (you can leave it called Guest if you want to) that is different from the gateway, only devices that you assign to Guest, with the different password, will connect to Guest. The other devices will connect to the gateway with the password assigned to the gateway.

@keg403  Even though I never had issues with my router determining the correct band for my connected devices to use, I have all of my 2.4GHz only devices connect to the Guest Network, which has a separate SSID and password. That also makes it a little more secure because the Guest Network is basically your internal network separate from your primary network. All of my IoT devices if you will (security cameras, Alexa, thermostat, washing machine, etc) use the Guest Network.
