RBR750 getting "500 Internal Server Error" after upgrade to v7.2.6.31

[larsks]

I have an Orbi RBR750 with two satellites. They hadn't been updated in a while, and a couple of devices in the house were having problems with consistent connections, so I decided to update all the things. The Orbi admin interface offered an automatic update to 7.2.6.31 from 4.something.

The upgrade seems to have competed successfully: I have wireless network access and the phone app reports that the satellites are connected to the main router.

However, any attempt to access the web interface results in "500 Internal Server Error".

Is there any way to recover from this *other* than performing a factory reset?

Thanks!

No, you'll need to reset and setup from scratch: https://community.netgear.com/t5/Orbi-WIFI-6-AX-AND-Wi-Fi-6E-AXE/Procedure-for-Factory-reset-of-RBS8...

Be sure the RBS were updated first before the RBR was.
