Netgear R6400 – AC1750 Smart WiFi Router—802.11ac Dual Band Gigabit 사용자 설명서

This section describes tips for troubleshooting some common problems.

When you must restart your network, follow this sequence:

Turn off and unplug the modem. 

Turn off the router.

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

Turn on the router and wait two minutes.

If your device does not power on, make sure that the Ethernet cables are securely plugged 
in. 

The Internet LED on the router is lit if the Ethernet cable connecting the router and the 
modem is plugged in securely and the modem and router are turned on. 

If one or more powered-on computers are connected to the router by an Ethernet cable, the 
corresponding numbered router LAN port LED lights. 

Make sure that the wireless settings in the computer and router match exactly. The wireless 
network name (SSID) and wireless security settings of the router and wireless computer must 
match exactly. 

If you set up an access list you must add each wireless computer’s MAC address to the 
router’s access list.

Make sure that the network settings of the computer are correct. Wired and wirelessly 
connected computers 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 cable modem service providers require you to use the MAC address of the computer 
initially registered on the account. You can view the MAC address in the Attached Devices 
page.
