Firmware upgrade capped satellite bandwidth at 50Mbps

The display seen for 2.4Ghz is for what Primary and Secondary channels that 2.4Ghz radios use. This is wifi and common standard operation and display. I've always see this on UIs. Nothing new here. No special app or modifications used here at all. MS EDGE web browser. 

Again, systems is working as expected and proves it works fine when the configuration IS clean and NOT using a old backup configuration from file.

We've let NG know about your backwards configuration problem. However I've seen MANY other router mfr with same problem. Mfrs add new stuff to FW making OLDER backups incompatible. Factory rest and setup from scratch is needed to generate a new and compatible backup file that works with newer FW. This issue isn't new and is seen across the router industry for years.  I personally never use older backups with new FW. I would agree, backups should work however if QA and testing isn't being done properly, then thats on NG side of things. No idea what goes on, on that side of the fence. I was a dev myself. 

Im out. Will let NG handle this from here on out. 

Good Luck.
