   That's usually a DNS problem; not fatal if the router's LAN IP
address works.

   Briefly, the idea is that "[www.]routerlogin.net" (or ".com") should
point to your own router, but that's true only if you use your own
router for DNS name resolution.  (Or, if the Netgear router can
intercept your DNS queries.)  Regardless, you should be able to get to
the thing using its (LAN) IP address, if you can determine (or guess)
that.  Normally, that would be something like "192.168.1.1" (for a plain
router) or "192.168.0.1" (for a modem+router), but it could be
different.  ("10.0.0.1" is a typical alternate, for example.)

   A new complication arises if your web browser uses "DNS over HTTPS"
(and some real-world DNS server directly).  In that case, those
"routerlogin" names will typically take you to that misleading/useless
Netgear error page.  Specifying the IP address (instead of a
"routerlogin" name) should work, but there are some exotic cases where
you might need to disable "DNS over HTTPS" in your browser.
