LTE CA aggregation issues after a while (minutes/hours) for MR1100-100EUS 12.06.11.00

[Sebastiii]

Hello,

My model : MR1100-100EUS_NTG9X50C_12.06.11.00

My provider antenna (French FREE 4G) has doing upgrade to 3CA (B7+B3+B28), settings the mode LTE All and it works correctly but not for long time, after the tower upgrade, I have done many test to see the different between mode 🙂

But I did notice pretty big bug, after a while (minutes or hours, it's random) the aggregation is not working correctly. The result is MR1 can't aggregate all CA, for example the MR1 only keep :

- PCC + SCC1

or

- PCC

Instead of

- PCC + SCC1 + SCC2 (working on fresh reboot or Band Region change)

The only way to have it back working on 3CA is to :

- Reboot

- Change "Band Region" to another settings (like "Auto") and set it back to "LTE All"

After doing above, it's back to 3CA for a while but quickly bug is back.

I'm pretty sure that it was the case also for 2CA (before towr update), because I have notified a bandwidth decrease after an among of time and was doing the above trick and bandwidth was back, at this time, I didn't look if it was an aggregation issue or not becaus I was sure all was OK.

To be able to look at aggregation PCC/SCC1/SCC2, I have connected MR1 to USB and telnet to doing testing and to view values with AT!GSTATUS? and here I did notice this bug.

FREE 4G France provider did aggregation activated when using data download  (not even too much), this way the 3CA is activated, so I call this "dynamically mode", I can't compare with other provider like Orange etc. but it seems to be an statically mode (3CA always activated) and not only when download data. I don't know if this is the root of cause or simply something else but for sure CA aggregation failed on MR1.

BTW, I already reset the router and configured from scratch and it's the same 😞

I'm hoping that NETGEAR support can look at this.

Thanks.
