Serial number not recognised. Model number not recognised LBR20 4g LTE router

I try to contact my support plan. It asks for my product regiustration number. I type it in exactly as it is printed on my router. 6 times and checked each time.

It is always marked in red as an invalid number. I cannot connect with support without the product number.

I justy spent a lot of money on this very expensive router and its supposed to give me 6 month support complimentaary. Yet as the site will not recognise the number I cannot use it.

In the troubleshooting section it asks about the leds on the product. There are no LEDS on it, but without selecting one of the two options, neityher of which apply, you cannot proceed further. If you do select one it does not refer to the product.

It wont connect to my printer, and again will not accept my password, though I have s picture of it saved.

Windows 10 up to date. Router software and firmware updated today by Netgear.

The device recognises phones that I have not had for three years, and networks that also I do not know.

All in all, my chinese router Huawie LTE router has better workings than this one, at less than a third of the price
