RBR750P Firmware

[CARIB909]

When I go to Downoads on the Netgear site after entering my router's model, I get a new firmware zip file. When I check from  orbilogin.com, the applet says "No new firmware". RBR750P and RBS750P are on firmware V4.6.14.3.

Version V6.3.8.5 is available for download. My router has not been updated in several years since I purchased it. Why is there this conflict of information?

There are only RBR750 and RBS750. There is no P version. 

Current release FW for the 750 series is here:
