2.4g devices not connecting to T-Mobile Home Network

I created a 2.4 settings network like the screenshot above and reset modem and phone afterwards. Do I need to change the original settings from 5 and 2.4 automatic to 5 only? I didn't want to change the original settings unless this was necessary. I also have the Arcadyan KVD21 Gateway if that makes a difference or not.

I Just got a 5G gateway (black tower model FAST 5688W), my eufy cams are not connecting to the 2.4ghz, but other devices can connect well (printers, tablets, tv, etc). I have tried with the default 5ghz/2.4ghz, also with single 2.4ghz and any combination of WPA/WPA2/WPA3 with no success. I also deleted all devices from my app and deleted cache in the cell phone. Does anybody know if eufy is not compatible with this type of gateway?

I’m using my eufy cams without issue in my Cox 2.4ghz network gateway.

I am trying to setup a 2.4ghz for some of my devices but even after doing everything mentioned above concerning the FAST5688w

i can not create a separate network. I enter all the info and it will not let me add or save. Can someone please help. I live in a box type house and any device will be away from the gateway

PIece of CRAP should automatically have both 5GHz and 2.4GHz turned on. This is just BAD DESIGN AND EXECUTION!🤬

Thanks for this thread, annoying as it is! 

I have been trying to get my Sonos One speaker set up for weeks, nay months. Another two hours on support today…. Got it all set up, but my new 2.4 network appears to be hidden, even though I never checked the box. I even changed it to WPA and WPA2 only (at separate times) which may be an issue for some of you out there. Still no luck for me though. The TMobile app says it's not hidden but Apple won't let me unhindered it?

Ideas? 
 

Also, a tip for others if possible change your set up device if possible. I got further along with my iPad than I did with my iPhone…..

Thanks and good luck out there on the Ethernet!

I just wanted to echo what @Feahp00 said - choosing 2.4Ghz alone may not be enough to connect to older devices. I also needed to choose WPA/WPA2 for the password settings in order to connect the devices to the new 2.4Ghz network. 

 

 

I am so grateful to you and @Katiejo123 ! I have been so annoyed with this for months. I was looking to buy a new vacuum because it seemed stupid to have one that I can't control with my app or Alexa as intended! Thank you!!!

I have done what is suggested but how do you add the devices to the specific network?

Thank you so much Katiejo123!  Your advice was exactly spot on.  My Samsung fridge could not find my T-mobile Gateway network (5G/2.4ghz, automatic) after many tries, so I did what you said: I added a designated 2.4ghz network to my system (which does not cost anything to those who might wonder) and specifically chose WPA2. It also was helpful to reset the Samsung fridge wifi too.  Finally I ran the entire process on the Smart Things app and my new 2.4ghz network was recognized and appeared as a network choice, and I made sure to use WPA2 (not combined WPA2/WPA3) and it finally connected!  Thanks for your solid advice! 

FYI :  If anyone it trying to get their SONOS speakers to work with T-Mobil 5G.

Sonos technicians are now saying the T-M 5G internet routers are not compatible with their speakers.

Yall are making this WAY harder than it has to be.

1. Open the T-mobile Internet app

2. Go to the Network tab at the bottom

3. Click on the "+" sign to add a network

4. Add in the information for a 2nd network and change the frequency band to 2.4 GHz.

 

Done. Easy. Now you have 2 networks and 1 is 2.4 only. I had to figure this out myself as this thread was trash. 

The modern version of this, on T-Life: Home > Home Internet > Add Network > Change frequency band to 2.4 GHz.
