When a NETGEAR Nighthawk RS300 shows no internet, the router is powered and its Wi-Fi works but the internet light is amber or white-off and web pages fail, so the problem sits between the router and the provider. NETGEAR's community threads on the RS300 describe two groups of cases. The first is firmware: some owners lost internet after updating to firmware 1.0.0.50 and recovered by reverting or by a factory reset and re-entering their settings.
The checks in more detail
The second is the ordinary cause, a modem that needs a restart or a provider setting the router must match. Start in order. Power the modem off, wait thirty seconds, power it on and wait until its lights settle, then restart the RS300 and wait a few minutes, as the ModemGuides guide recommends for the whole Nighthawk family. Check that the cable from the modem is in the router's internet port, the one marked for WAN, not a LAN port, and that the cable is good.
Log in at routerlogin.net or the router's app and open the internet status. If the router shows a private address with no gateway, the provider may need the router's MAC address registered, which some cable providers still require after a modem swap. If your connection uses PPPoE, the username and password must be entered under Internet settings. Check that the date and time are right, since a wrong clock can block some connections.
If a firmware update came just before the fault, check NETGEAR's firmware page and the community thread for a newer release or a rollback. As a test, connect a laptop straight to the modem; if it has internet, the router is at fault, and if not, the provider is. A factory reset by holding the reset button for about ten seconds sets the router to defaults; set it up again with the app. If the fault remains, NETGEAR support can help.
