Would anyone know how to change the rekey interval on the Orbi RBR20? I dont see this option anywhere in the advanced settings. Failing that, would anyone know what the default interval is set to?

The group rekey interval appears to be set to zero.  i.e. there are three parameters that have "rekey" in them and appear to relate to this:

To see all Orbi parameters, activate telnet on http://orbilogin.net/debug.htm, telnet into the router, and type this command:

nvram show

To see only parameters with "rekey", type this command:

nvram show | grep "rekey"

What I infer from this is that the Orbi product does not constantly reset the WPA key.  I confess to not understanding much about WPA-PSK.  What I sense is that there is some mechanism built into the WPA standard for the access point and device to update the shared key without losing conection which would mean that someone snooping on the WiFi stream would be collecting packets where the key changes every so  often and this would make cracking the encryption exponentially more difficult.
