Netgear AC1200 Owner's Manual

This section describes tips for troubleshooting some common problems.

When you need to 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 2 minutes.

Turn on the router and wait 2 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 on if the Ethernet cable connecting the router and the 
modem is plugged in securely and the modem and router are turned on. 

For each powered-on computer connected to the router by an Ethernet cable, the 
corresponding numbered router LAN port LED is on. 

Make sure that the wireless settings in the computer and router match exactly. 

For a wirelessly connected computer, the wireless network name (SSID) and wireless 
security settings of the router and wireless computer need to match exactly. 

If you set up an access list in the Advanced Wireless Settings screen, you have to 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 need to have 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 screen.
