Wireless SSID (Service Set Identity): A name that uniquely identifies a wireless network. All clients that want to communicate with the Broadband

Wireless Router (AP) must have the same SSID as it.

Desired Channel: The frequency in which the radio links are about to be established. Usually the clients will scan the whole operable channels and then select the desired communications channel automatically.

WEB SERVER

6.7 WEP

The privacy security function can enhance media security by encryption technology. All clients must set the same encryption key to maintain the tightened communication with the Broadband Wireless Router (AP) properly. To turn on the privacy function:

Authentication Algorithm: Select Enable WEP as the authentication type.

Select Enable WEP: Open Key

If Open Key is selected as the authentication type, a wireless station can associate to any wireless network available in the air and receive any messages that are not encrypted.

Note: Open Key is also referred as Open System in some models.

Disable WEP: Shared Key

With shared key authentication, only those wireless stations that possess the correct WEP keys can join the wireless network.

WEP Encryption

To enable WEP encryption function, select your encryption length as 64-Bit or 128-Bit .

When entering your WEP keys, notice that your WEP keys must be comprised of hexadecimal characters (0-9, A-F, and a-f) and must contain 10 characters for 64-bit WEP

Keys or 26 characters for 128-bit WEP keys.

FAQ

7. FAQ

Q1.Can I switch between a notebook and PC using the same cable modem? Will there be a problem to obtain a DHCP IP address?

A. This issue depends on how your cable modem service provider manages the modems. If you are using one of the cable modem service providers that register your PC based on the MAC address of the Ethernet card in the PC, then you will have to call them and have them change that entry every time you switch between the two. Ask them if you have problem on this issue.

Q2.Can I use the same cable line for TV and cable modem?

A. Yes, the TV and cable modem uses the cable line. You need a splitter to use them at the same time. Ask Cable Company to install the splitter for you to avoid signal degradation.

Q3. My cable modem cannot get a solid green light on the Status LED when I connect the cable back.

A. The cable modem lost the signal during the disconnection period and it will keeps scanning other available signal. When you connect the cable back, it might take a while to find the correct channel. You can power cycle the modem to speedup the process since modem will remember the channel last time and it will start from that channel at startup.

Q4. Which port of the Ethernet hub should I connect to the modem if I need to connect multiple PC to the modem?

A. You should connect the modem to the up-link port of the hub. The link

LED of the hub will be on.

Q5. How do I see my IP address?

A. If you are using Windows 95/98/Me, the winipcfg command will show you to IP address of the PC connected to the cable modem. Notice that even though you seem get the same address all the time, it may still be a dynamic address.

Q6. Can I just connect the cable modem and two computers to a hub?

A. Yes. You need to make sure you can get two IP addresses from your cable modem service provider. Connect the modem to the up-link port of the hub.

48

FAQ

Q7. I have a cable modem. How can I make it work?

A. Basically, modem is plug and play. You can just connect the modem and you are ready to go if you have the subscription. For ensure good signal for your cable modem, you should ask your cable provider to install the cable modem for you.
