I have a dedicated firewall and wifi already setup and would like to disable wifi and routing in the t-mobile device so that it’s effectively just a modem.  Is this possible with this device?

If you got the newer 5g model that is grey and looks like a trashcan, then the answer is you can’t.  It’s just a 5g hotspot.

It looks like a trash can to me….I’ll play with the setup on my router and see what I can make work….thanks

Can I change the up subnet in the dhcp settings?  It conflicts with my internal IPs

Update.  I’ve been through all the settings in the web ui and I can’t find any way to change the 192.168.12.0 network setup.  I get that T-Mobile wants to make the setup simple but there’s no way I’m going to be able to work with this device if the only real configuration is English vs Spanish….

if anyone has had any success setting this up with a secondary router please chime in with any advice.  Otherwise I’m going to have to return this “trash can” to t-mobile.  It’s too bad bc in my area the signal is good and initial speed tests looked promising for this to be a viable alternative to cable…it’s a shame that basic router configurability could keep me from what otherwise looked to be a promising solution…

 

Has anyone an update on this?  I hear that it can be done but I'm not finding any helpful  information.

Here is my 2 cents on this:

  • There is no way to change the ethernet / wifi subnet.  It is 192.168.12.0/24.  Same ipv4 subnet bridged across wireiess/wired.  There is also ipv6.
  • You can disable wifi, with a little work.  You’ll need to go into each of the 12 SSIDs and turn off ‘enable SSID’.  Status page will still show wifi on, with channel and strength.  But, in statistics / WLAN page, it should show as:
    2.4GHz WLAN Connection Disabled
    5GHz WLAN Connection Disabled
     

    As far as I can tell, wifi is not on at this point.

    It would be great in situations like this to be able to have this device bridge external to internal interface like many cable modems allow, passing the external IP directly to an internal firewall / router device.  But, that isn’t an option.

    If you use your own router / firewall, you are likely double NATing.

    External IP - Home Gateway - 192.168.12.x - firewall - internal IP space

    Not pretty, but will likely work for many types of connections.
