I have an old router which has been tossed out

The RS went the way of the dodo bird because it stopped functioning and went to the electronics heaven in the sky.

And to reiterate, I cannot contact support for this product, because when I go to the support page, I have to either enter the product that I own (I no longer own this product) OR have a subscription. Since I don't own the old product, nor have a subscription to the old product or the new product, I cannot create a support case, and thus cannot get support or call the phone number because I don't have a case.
