2.4g devices not connecting to T-Mobile Home Network

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 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.

Mine is about 10feet around a corner.  Working from my phone app.  Did you do the WPA/WPA2 setting?  That's the key.  Try also rebooting your phone.

The above, unfortunately, did not work for my shark vacmop. Do you have your robot vacuum close to the router? Mine is probably 10 feet away and through a wall. I didn't know if I should try moving my vacuum closer or not. I really don't want the hassle.

Thanks Andrewborstein,

That worked for me also.  

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. 

The 2.4 devices are older and the WPA of the network needs to be changed to WPA/WPA2. Making this change to my 2.4 network let it connect to my Shark robot. 

This needs to be documented by T-mobile.  I have the same issue with some devices that accept 2.4G only.  Went through and created a second SSID (see Katiejo123 above). 

Went to 192.168.12.1 as mentioned by Cat Call but there is no sign-in link and cannot do anything.

According to sources 2.4G works best on channels 1, 6 and 11.  T-mobile assigned the new SSID to channel 4.

The issue of connecting 2.4G devices needs to be resolved.  If I attache a separate router that has 5G and 2.4G, to the device I can then connect my 2.4G devices.  BUT this should not be the case.

I had to figure this out myself as this thread was trash. 

Just realize that the option to add a network through the app was only recently available,  not 2 months ago.
