Hi folks!

This post is no joke, actually. Although, for 99% of users this practice is a joke anyway, and completely useless.

So I put that disclaimer above in place just to give fair warning, although from testing; it has been a safe and smooth experience. I have spent WAY too much time recently studying AT commands and the R11e-LTE6 firmware, not to mention conducting far too much trial and error. My LHG-LTE6 is out of warranty, so I have no concerns about warranty/RMA. Your situation may be different. So be warned/careful!

I was never able to find a way to disable carrier aggregation in my router. In my situation; carrier aggregation doesn't always work properly, for reasons I may never understand. Although on my iPhone it does work wonderfully, also for reasons I may never understand. Well, anyway, if for whatever stupid reason you want to disable carrier aggregation on the R11e-LTE6; here is how to do it. Bear in mind that I am a total n00b, so there is very likely a much better way of doing this, but I am open to learning!

Open a New Terminal window and copy and paste the following commands, and then press [Enter]. You should see "output: OK" if it worked.

Used/tested on RouterOS 7.18.2 (stable) and R11e-LTE6 firmware R11e-LTE6_V038.

Disable Carrier Aggregation: (wait for modem to reboot and reconnect)
Code:
/interface lte at-chat lte1 input="AT+ZCACFG=0,ffffffff;+RESET"
Reset to Defaults: (wait for modem to reboot and reconnect)
Code:
/interface lte at-chat lte1 input="AT+RSTSET"
I hope this is of actual use to someone, or is at least a bit of entertainment. Please let me know if you have any questions or get stuck. I'm only exploring this stuff part-time, but I can try to help if I can.

Good luck, and enjoy!
