2.4 ghz not showing
I've had Tmobile Internet for about 7 months now. I did not have this problem until yesterday. I moved my router to a new location to see if I could connect to devices in the basement - didn't work, so I moved the router back to its original spot.
However, once I made the move my 2.4 network is no longer showing as an option to connect. Not on my android or any device. I have a 5 and 2.4 set up with different SSID Names. I need to have my phone connect to the 2.4 so I can reinstall my Wyze Cams that came disconnected after moving my router.
I've seemingly tried everything - restarting phone, restarting router, resetting networks, power on, power off, even called Tmobile and was told they have to call me back Friday!!
Any help would be appreciated
- Check router settings to ensure both 2.4 GHz and 5 GHz networks are active.
- Ensure the 2.4 GHz network SSID is visible (not hidden).
- Confirm your device supports the 2.4 GHz network.
- Try forgetting and reconnecting to the 2.4 GHz network on your devices.
- If all else fails, contact your internet service provider for assistance.
I contacted TMobile and did a factory reset of the modem and re-installed everything. So far, so good.
But I do not understand it, and I do not understand if this will happen again. it was a complete pain the bottom to do this
Also, one other thing when it came back up after re-set everything was trying to set to WPA3 for security. A lot of devices can’t work with WPA3, so set it to WPA2 and it works fine.
It seems that the April 2024 firmware update disabled the 2.4 GHz band. I was not aware of this when I made my earlier posts in this thread.
This forum member resolved the problem with a gateway reset:

How do you rollback a firmware update?
FWIW:A day later and a 2.4 ghz signal is still not being advertised (after reboot, etc). I could not find a direct solution, I didn’t have the time to phone in (and shouldn’t have to), but I did have a spare router. So I set up the spare router as an access point, for wifi only (Obviously, I shouldn’t have to do this (but judging from other posts on this forum over the years, this issue keep re-occuring with different firmware updates))..
Similar story here.
A recent update (5G Gateway G4AR-1, now firmware v 1.00.09) broke 2.4Gz networks on my router.
They are no longer advertised, no matter what I do (rebooting, etc.).
No device can see it any longer.
Does anyone from T-Mobile look at these forums?

I am having this same issue. 2.4 does not work.
I have created a new 2.4 network and no device can see it, period
How did you uninstall the firmware updates?
I was able to remove Thursday night’s fw push and the router resumed normal operations. Called ATT to have them provide internet. I cannot afford any service interruption again. That would end my career.
Have you unplugged the gateway for 30 seconds? The next step would be to reset the gateway and re-configure your networks. And finally, to call support. 🫰
Already did all of that. The TMobile router will no longer advertise anything 2.4G.
Just add a second network, configured to 2.4 GHz only. Try WPA2/WPA3. If your devices can’t connect to this, reduce the security to WPA/WPA2.
