I just purchased a 3rd Nano HD AP to improve the coverage of my network. The other two have been in place for about 9 months. They are currently at FW version 4.3.21. I was surprised to see that the new AP came with 5.16.0 out of the box. Now that it's adopted and provisioned, I'm offered the option to downgrade the FW on the new one.
When I look at the FW download page on Unifi, I find no mention of the 5.x versions.
Is there a reason to downgrade the FW on the new one? Will it cause issues? Anyone know anything about this 5.x version of the firmware? I'm kind of baffled on this one.
