No Serial No

Just got myself an Orbi RBR50 from a bidding site.

Unfortunately I had to resert is as there was no user and password sent with it.

Went through the normal factory reset, but it won't accept the serial number from the label.

Can anyone suggets anything?

If you factory reset the RBR by pressing the reset button for 15 seconds then release, go to 192.168.1.1 in a web browser and walk thru the setup wizard here. No serial number will be needed here.

A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. https://kb.netgear.com/22697/How-do-I-install-my-NETGEAR-router-using-the-router-web-interface
Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

I would power OFF the ISP modem for 1 minute. Factory reset the router and power it off. Power ON the ISP modem and let it sync. Then power ON the router and walk thru the setup wizard again using a wired PC and a web browser.
Press the back reset button for 15 seconds then release.
