MR2100 – Nighthawk M2 Mobile Router Firmware Downgrade

[smurfj3]

I am having issues since the latest firmware version so I would like to do a rollback. However I can't seem to find previous firmware versions for my device. I am looking at the following page to find older versions: https://www.netgear.com/support/product/mr2100#download

Is there another place I can find older versions? The reason I want to downgrade is that I can't seem to access my IPcameras anymore using 2.4ghz wifi, only 5ghz, which is extremely weird because 2.4 was working fine before the upgrade. I've tried factory reset, changing the bandwidth from 20mhz to 40mhz and tried changing encryption but it nothing seems to make a difference.

Is the 2.4Ghz band enabled?  I know that it's off by default on my M6 and needs to be reenabled after a factory reset.  Just a thought.
