MODEM PROBLEM

Cannot access the Internet

Check the IP address. Follow the steps for verifying the IP address

in

Verify & Renew Your IP Address

. If you need an IP address, call

ARRIS SURFboard Technical Support for assistance.

POWER LED Icon is OFF

Check the power connection between the gateway and the

electrical wall outlet.
Check that the electrical outlet is working (is the outlet controlled

by a light switch?).
If so, disconnect and find another electrical wall outlet.

Cannot Send or Receive Data

Check each end of the coaxial cable connection on the gateway

and cable outlet. Hand-tighten, if necessary.
Check the Ethernet cable to make sure it is properly connected to

the gateway and computer.
On the front panel, check the status of the LED icons and refer to

Front Panel LED Icons and Error Conditions

to identify the

problem.
If you have cable television, check your television to ensure your
cable service is operating properly.

Wireless devices cannot send

or receive data

If the problem still persists after checking the coaxial cable and
Ethernet connections and your IP address, check the Security
Mode
setting on the Wireless Primary Network screen.
If you enabled WPA and configured a passphrase on the gateway,

be sure each affected wireless client has the identical passphrase.
If this does not solve the problem, check if the wireless client

supports WPA.
If you enabled WEP and configured a key on the gateway, be sure

each affected wireless client has the identical WEP key. If this
does not solve the problem, check whether the client’s wireless

adapter supports the type of WEP key configured on the gateway.
