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 44.
Your cannot connect over an
Ethernet cable to the modem
router.
Make sure that the Ethernet cables are securely plugged in.
Make sure that your computer or 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.)
You cannot connect over WiFi
to the modem router.
Make sure that the WiFi settings in your WiFi device and modem router
match exactly.
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 of
the Main Network on page 56.
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.
Make sure that the modem router’s SSID broadcast is not disabled.
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.)
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 13).
If this LED is off, both WiFi radios might be disabled. For more information
about the WiFi radios, see Control the WiFi Radios on page 73.
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 of the Main Network on page 56.
