Mobile card disappearing band selection

[gingerninja234]

Hey @seud0nym,

Not sure if it is my setup or modem… but once I change the active bands on the Mobile card the tick boxes disappear resulting me in having to do a full factory reset to get the bands back

Tried reinstalling tch-gui-unhide with no luck unfortunately

Hopefully the screenshot helps

Run the following command in PuTTY (or equivalent) before selecting the bands:

transformer-cli get rpc.mobiled.device.@1.capabilities.supported_bands_lte

It should return:

root@test:~# transformer-cli get rpc.mobiled.device.@1.capabilities.supported_bands_lte
rpc.mobiled.device.@1.capabilities.supported_bands_lte [string] = 3 7 28

After you have changed the active bands, run it again.

Post both the before and after results back here.

Thanks.

Here are the results:

Before change: root@mymodem:~# transformer-cli get rpc.mobiled.device.@1.capabilities.supported _bands_lte rpc.mobiled.device.@1.capabilities.supported_bands_lte [string] = 3 7 28

After change (disabling band 7, no change to GUI): root@mymodem:~# transformer-cli get rpc.mobiled.device.@1.capabilities.supported _bands_lte rpc.mobiled.device.@1.capabilities.supported_bands_lte [string] = 3 7 28

After change (enabling band 7 but disabling band 3/active band. GUI selection disappeared): root@mymodem:~# transformer-cli get rpc.mobiled.device.@1.capabilities.supported _bands_lte rpc.mobiled.device.@1.capabilities.supported_bands_lte [string] = 3 7 28

Strange. It should only hide the check boxes if supported bands capability comes back empty. I will do some more research.

What device and firmware are you using?

Does "VF Web" mean you are using a Vodafone SIM? Can you do a test with the original Telstra SIM?

On my test DJA0230 running 20.3.c.0389, I just connected using the default Telstra SIM. It selected band 7, so I then deselected 7, and saved. The checkboxes were all still there, and it switched over to band 3.

Device is a DJA0231 with the latest firmware, 20.3.c.0501-MR22.1-RA

Yes that’s right, using a Vodafone sim as a test. I’ve just popped the Telstra sim back in and unfortunately the tick boxes aren’t showing up, so I can’t enable and disable the bands

[seud0nym]

I think the issue is that the Device Status is "Connecting" in all the screen shots you have provided. You can't configure the bands until the status is "Connected".

[gingerninja234]

Hmmm okay, I see what you mean. Hopefully it eventually connects!

I’m in the inner suburbs of Melbourne, so it shouldn’t be an issue I would’ve thought

[seud0nym]

What do the Network Status and Service Status show on the Diagnostics tab?

[gingerninja234]

So I've given the modem a reboot and the band selection has popped up again. It's showing as connected now after the reboot...

[gingerninja234]

Okay so I've swapped back to the Vodafone SIM and bands have disappeared again. Also noticed the "Operator" and "Roaming dropdowns have disappeared too. Didn't get a chance to change it back to "Vodafone" so it might not connect

[gingerninja234]

Looks like an issue with my modem trying to provision settings. I swapped over with my other booster modem and that one was working fine so I guess there’s no problem. I’ll close this issue for now since it’s not a problem to solve. Thanks for having a look into it!
