Port 1812 is the reserved RADIUS-authentication port described in RFC 2138. Earlier AP (RADIUS clients) use port 1945. The default value will be shown on this box. You can keep and use it. RADIUS Key: A RADIUS Key is like a password, which is used between IAS and the specific RADIUS client to verify identity. Both IAS and the RADIUS client must be use the same RADIUS Key for successful communication to occur. Enter the the RADIUS Key. WPA/WPA2
Chapter 2: Web Configuration 34For the WPA/WPA2 network Authentication, the settings that you can adjust including WPA/WPA2 Encryption, RADIUS Server, RADIUS Port, RADIUS Key, Group Key Rotation Interval, and WPA/WPA2 Re-auth Interval. WPA/WPA2 Encryption: There are three types that you can choose, TKIP, AES, TKIP+AES. TKIP takes the original master key only as a starting point and derives its encryption keys mathematically from this mater key. Then it regularly changes and rotates the encryption keys so that the same encryption key will never be used twice AES provides security between client workstations operating in ad hoc mode. It uses a mathematical ciphering algorithm that employs variable key sizes of 128, 192 or 256 bits. RADIUS Server/RADIUS Port/RADIUS Key: Please refer to the previous page. Group Key Rotation Interval: Key in the time for the WAP group key rotation interval. The unit is second. With increasing rekey interval, user bandwidth requirement is reduced. WPA/WPA2 Re-auth Interval: When a wireless client has associated with the EMTA Gateway for a period of time longer than the setting here, it would be disconnected and the authentication will be executed again. The default value is 3600, you may modify it. WPA-PSK/ WPA2-PSK For the WPA-PSK/WPA2-PSK network Authentication, the settings that you can adjust including WPA/WPA2 Encryption, WPA Pre-Shared Key, and Group key Rotation Interval. WPA Pre-Shared Key: Please type the key to be between 8 and 63 characters, or 64 hexadecimal digits. Only the devices with a matching key that you set here can join this network.

I can’t access the internet. z Check all of the connections to your EMTA Gateway. z Your Ethernet card or USB port may not be working. Check each product’s documentation for more information. z The Network Properties of your operating system may not be installed correctly or the settings may be incorrect. Check with your ISP or cable company. All of the lights are flashing in sequence. z This means the EMTA Gateway is automatically updating its system software. Please wait for the lights to stop flashing. The updating process typically lasts less than one minute. z Do not remove the power supply or reset the EMTA Gateway during this process. I can’t get the modem to establish an Ethernet connection. z Even new computers don’t always have Ethernet capabilities – be sure to verify that your computer has a properly installed Ethernet card and the driver software to support it. z Check to see that you are using the right type of Ethernet cable. The modem won’t register a cable connection (CABLE LINK light not on continuously). z If the modem is in Initialization Mode, the INTERNET light will be flashing. Call your Cable Company if it has not completed this 5-step process within 30 minutes, and note which step it is getting stuck on. (See page 24 for details.) z The modem should work with a standard RG-6 coaxial cable, but if you’re using a cable other than one your Cable Company recommends, or if the terminal connections are loose, it may not work. Check with your Cable Company to determine whether you’re using the correct cable. z If you subscribe to video service over cable, the cable signal may not be reaching the modem. Confirm that good quality cable television pictures are available to the coaxial connector you are using by connecting a television to it. If your cable outlet is “dead”,
Chapter 3: Additional Information 42 call your Cable company. z Verify that the Cable Modem service is DOCSIS-compliant and PacketCable-compliant by calling your cable provider. I don’t hear a dial tone when I use a telephone. z Telephone service is not activated. If the rightmost light on the EMTA Gateway stays on while others flash, check with your TSP or cable company. z If the EMTA Gateway is connected to existing house telephone wiring, make sure that another telephone service is not connected. The other service can normally be disconnected at the Network Interface Device located on the outside of the house. z If using the second line on a two-line telephone, use a 2-line to 1-line adapter cable.
