Netgear R7800 - Nighthawk X4S AC2600 Smart WiFi Router 사용자 설명서

This section describes tips for troubleshooting some common problems.

Turn off and unplug the modem.

Turn off the router.

Plug in the modem and turn it on. Wait two minutes.

If you set up an access list on the Advanced Wireless Settings page, you must add each WiFi computer’s MAC
address to the router’s access list.

Make sure that the network settings of the computer are correct. Wired computers and computers that are connected
over WiFi must use network IP addresses on the same network as the router. The simplest way to do this is to
configure each computer to obtain an IP address automatically using DHCP.

Some service providers require you to use the MAC address of the computer initially registered on the account. You
can view the MAC address on the Attached Devices page.

return the LEDs to their standard settings for troubleshooting. For information about controlling the LED settings,

After you turn on power to the router, verify that the following sequence of events occurs:
