NETGEAR Nighthawk routers has Wi-Fi but no internet

The checks in more detail

The Power LED should be solid green or white, since solid amber means powering on and blinking amber means firmware is upgrading or the Reset button was pressed. NETGEAR's troubleshooting index has a page on recovering a lost connection, one on a new router with no internet because of MAC spoofing, and one on what to do when you cannot reach the internet on a Nighthawk. Power cycle the modem and the router, reseat the cable, try a different cable, and connect a computer straight to the modem to test the provider.

If the computer works on the modem but not through the router, look at the provider's need for a specific MAC address, or reset the router with the seven-second Reset press. When you contact the provider, tell them what the modem lights show, that a computer works or does not work plugged straight into the modem, and that the router is an Orbi. That avoids the scripted questions about restarting equipment you have already restarted. If several devices lose internet but the ring is not magenta, look at the modem's own lights and your provider's outage page first, and keep a note of the modem's lights at the moment of failure.

A magenta router ring that clears itself after a modem restart usually means the modem was the problem; one that returns within minutes suggests a line fault worth reporting to the provider with the time of each failure. Photograph the front-panel LEDs before you start, because the pattern of Power, Internet and WiFi lights is the fastest thing to tell NETGEAR support, and it also lets you compare the state before and after each restart. If the fault appears only in the evening, it is likely congestion or the line, and logging the time of each failure gives the provider something concrete to check.
