Hi

Based on the firmware version of your MR600, we suspect that it was supplied by your internet service provider. We recommend reaching out to your provider to verify if there is a beta version available.

Hello Joseph

I found my current firmware shared on this forum. It was not provided by my ISP.

Previously I had the latest official firmware that I updated by going through the inbuilt firmware updator.

The reason for flashing the current firmware was to get the option to disable the ghost wifi created by "one-mesh" feature.

So back to the original issue, is there a beta firmware that allows selecting Band A and Band B separately on the MR600 V2. I have attached a screenshot of this feature on MR600 V1 below for better understanding:

  @stockreaper hi, if you're still searching for answer : you can actually select 2 bands, click on Search then it should display the availble bands. Select two.

If you only see one band when clicking Search, exit and try again.

Worked for me and i managed to get 4G+ most of the time (I suspect when load is low it only use 4G, then use 2 bands when 4G+ makes sense)
