Max hd4 mbx 5g:

@TK_Liew Hi TK. It’s time for some sort of update. Please…


  • No band aggregation
  • No band selection or capability to select preferred bands.
  • Sometimes the band doesn’t display, although connected
  • No selection for LTE, 5G, etc.
  • No 5G connection or indication of anything.
  • SINR never displays.

Thank you!

Hi @TK_Liew,

is this included in the 8.1.2 beta now? Or are there plans to bring this in the GA?


@dennis.hofheinz @s.schneider @joelbean

Engineering team is working hard for the above features. 5G technology is not like what we experience so far for LTE/LTEA and this why some of the available options for the 5G device is not the same like LTE/LTEA models.

We have the following improvements in 8.1.2 firmware (RC2 now) :wink:

Band & Signal info :

5G/LTE selection:
Auto referring to 5G & LTE
LTE referring to LTE Only

Thank you


@sitloongs Thank you for this. I’m seeing aggregation now. If I could only select different bands for my ATT connection, I’d be ecstatic. :slight_smile:


can you show what engineering data shows? i’m interested in what module is installed?

thank you for this, i haven’t seen this hit the fcc yet

Just installed 8.1.2 RC3 on my Max Transit 5G and can no longer connect using Tmobile SIM that was previously working in the same location with the same antenna. Now I just get “connecting” or “obtaining IP”.

Reverting to 8.1.1 also no longer works. “no sim card detected”. Have tried both sim slots. @sitloongs @TK_Liew please help!


Can you confirm the 8.1.1 firmware version and build you are using for the Transit 5G ?

8.1.1 Build 5040 which was downloaded directly from the Pepwave repository.


For Transit 5G device , please use the following firmware 8.1.1s076 :

Known issue found for Transit 5G for 8.1.2 (RC3 now) & 8.1.1 GA and we will release the 8.1.2 special firmware to fix the issue when 8.1.2 GA released.

My 5G appears to be working fine with 8.1.2 build 5126 (without band selection). Am I supposed to use 8.1.1s076?

@sitloongs build 5076 is working now on LTE thank you, but still unable to connect to 5G.

@joelbean are you using a transit 5G?

Yes. It seems to have been fine since upgrading to 8.1.2 build 5126. No TMobile for me though.

@joelbean Looks like we have different devices

@sitloongs Do you have a predicted release date for 8.1.2 for the Transit 5G?

Estimate when we can get access to custom band selection?

I haven’t heard any updates in awhile. I would also like to know.

Good morning.
What is the estimated time for an MBX 5G firmware update that allows selection of bands?
Also, should the MBX 5G be able to see AT&T 5e bands?

Thank you.

Bump. Please provide an update to this inquiry. Thank you.

I’m using an 5G HD2 MBX.

Sorry for the delay. It is under development for the band selection for 5G module. I have relayed your requests and messages to the engineering team.
