Possible Solution

 

 

Your network is unresponsive

Restart your network:

or does not function normally.

1. Turn off and unplug the DSL, cable, or fiber modem.

 

2. Turn off the modem router.

 

3.

Plug in the DSL, cable, or fiber modem and turn it on. Wait two minutes.

 

4. Turn on the modem router and wait two minutes.

 

If network problems still occur, make sure that your ISP does not require you to

 

use the MAC address of the computer that was used to initially register the ISP

 

account. If your ISP does require that you do this, you must change the router

 

MAC address that the modem router uses. For more information, see Manually

 

Set Up the Internet Connection on page 29.

but is configured to receive an IP address automatically with DHCP. (For

 

 

most devices, DHCP is the default setting.)

 

 

 

You cannot connect over WiFi

•

Make sure that the WiFi settings in your WiFi device and modem router

to the modem router.

 

match exactly.

 

 

For a device that is connected over WiFi, the WiFi network name (SSID)

 

 

and WiFi security settings of the modem router and WiFi computer must

 

 

match exactly. The default SSID and password are on the product label (see

 

 

Bottom Panel Product Label on page 10).

 

•

Make sure that your WiFi device supports the security that you are using

 

 

for your WiFi network (WEP, WPA, or WPA2). For information about WiFi

 

 

security settings, see Manage the Basic WiFi Settings and WiFi Security on

 

 

page 49.

 

•

Make sure that the modem router is not too far from your WiFi device or too

 

 

close:

 

 

- Move your WiFi device near the modem router but at least 6 feet

 

 

(2 meters) away and see if the signal strength improves.

 

 

- Make sure that the WiFi signal is not blocked by objects between the

 

 

modem router and your WiFi device.

 

•

Make sure that the WiFi LED on the modem router is not off.

 

 

If this LED is off, the WiFi radio might be disabled. For more information

 

 

about the WiFi radio, see Manage the WiFi Radio on page 56.

 

•

Make sure that the modem router’s SSID broadcast is not disabled.

 

 

If the modem router’s SSID broadcast is disabled, the WiFi network name is

 

 

hidden and does not display in your WiFi device’s scanning list. To connect

 

 

to a hidden network, you must type the network name and the WiFi

 

 

password. For more information about the SSID broadcast, see Manage the

 

 

Basic WiFi Settings and WiFi Security on page 49.

 

•

Make sure that your WiFi device does not use a static IP address but is

 

 

configured to receive an IP address automatically with DHCP. (For most

 

 

devices, DHCP is the default setting.)
