XR500 no power light, no Wi-fi lights no internet

Thanks for this - I have had a look through the documentation and it often just refers me to steps I have already taken.

I had a look at how to install the firmware update as that was something I've not previously attempted - only to see that you need to be connected on the same network and access www.routerlogin.net, which is currently impossible as it isn't providing a joinable network.

The power light continuosly remains solidly off, according to the documentation: "Off. Power is not supplied to the router." but the Ethernet and USB LEDs are lit... so I'm a little lost there.

Similarly the Internet LEDs remains off, and according to the documentation: "Off. No Ethernet cable is connected between the router and the modem" - Despite there literally being an ethernet cable plugged directly from the modem into the router.

The wifi on/off button seemingly does nothing, as well as doing a complete reset by holding the reset buttong for 7 seconds.

When I opened the Netgear Nighthawk app after realising the internet has been a bit iffy, I could see that the router was displayed as "Disconnected" I removed the device as that was the only option and attempted a new system set up. This does not work as the router simply is not providing a joinable network. When I use the QR code, it prompts me to join the wifi network, but shortly after errors and says "unable to join network"

I did see a question that someone previously asked on here detailing the exact same issue, they had no responses or resolutions either, unfortunately.
