Preparations System Requirements Installing a Network Card Before connecting the wireless cable modem to your PC, make sure your system is equipped with a LAN controller or wireless LAN module and supports the TCP/IP protocol. If your system does not have an embedded LAN controller, you must install a network interface card as instructed below (assuming that you are using an Ethernet card under the operating system of Windows 98): 1. Install an Ethernet card on your motherboard. 2. Power up your PC and follow the Add New Hardware Wizard s instructions to install the driver. When asked to restart your computer at the end of the installation, click Yes. 3. After restarting the system, right-click My Computer on the desktop, select Properties, click the Device Manager tab, and then double-click Network adapters to confirm that the Ethernet driver is properly installed. 6 Wireless Cable Modem User s Manual

Serial Port The 9-pin D-sub serial port supports the RS-232 terminal interface for advanced cable modem management. 5. 10/100-BaseT LAN Ports The LAN ports support 10Base-T or 100Base-TX networks. These ports allow your PC or Ethernet hub to be connected to the cable modem through a CAT.5 twisted pair LAN cable. 10 Wireless Cable Modem User s Manual
Using the Wireless Cable Modem Installing the Wireless Cable Modem Take the following steps to accomplish the installation procedure: 1. Connect the cable TV coaxial cable to the input connector of a signal splitter. 2. Connect a coaxial cable from one of the output connectors on the splitter to the input connector of your TV set. 3. Use another coaxial cable to connect the other output connector on the splitter and the RF connector on the rear panel of the wireless cable modem. 4. Connect the LAN cable from the LAN port on your computer to the LAN port on the rear panel of the wireless cable modem. You can also connect to a PC with wireless PC card (see Configuring Wireless Settings ) 5. Connect the AC power adapter to the DC +5V/2.5A input jack on the rear panel of the wireless cable modem. Plug in the AC power adapter to an electrical outlet. 6. Powering Up: When all connections have been properly made and the power is ON, the wireless cable modem will automatically start the self-test and search for the active cable channel provided by your cable operator. NOTES: If you are not using a television on the cable line, you may skip steps 1 to 3 and connect the cable TV coaxial cable directly to the RF connector on the rear panel of the cable modem. Install the Wiireless cable modem as high as possible. Wireless Cable Modem User s Manual 11

Wireless Settings Click Wireless you can change ESSID/Channel/WEP Type/AP mode/wlan Enable. ESSID: ESS stands for Extended Service Set. The ESS ID is the name shared among all points in a wireless network system. The ESSID must be identical for all points in the system and must not exceed over 30 characters. After changing, please click Apply button for setup. Domain: Domain indicates the channel number for each country which is allowed to be used. For Example, Japanese All is the domain for the Japan for which the user can have 14 channels for his application. Channel: The value of channel can be selected from channel 1 to 11 for the FCC domain and between channels 1 to 13 for ETSI domain, as well as channel 1 to 14 for Japanese domain. WEP: Wired Equivalent Privacy is a data privacy security mechanism based on a 40 bit shared key algorithm. There are the options for Disable to disable the WEP function or enable the WEP with 64Bit or 128Bit. Enable the WEP and click the Apply will guide you another page for WEP key setting. AP Mode: Enable means the Wireless cable modem works only as an Access Point without cable modem function. To have the communication with CMTS, please click the Disable WLAN Enable: Disable means the Wireless cable modem works only as a normal cable modem without active the wireless functions. To have the communication with Wireless station, please click the Enable If you want to save the configuration data, please click Apply button and afterwards it will become default configuration. After change the new parameters to the Wireless Cable modem, you need to reset the modem to active the new settings. 14 Wireless Cable Modem User s Manual
Wireless Settings WEP Settings WEP Manual: Automatic Passphrase:To generate the key, if the WEP is enabled. This is the code used while a wireless point is to log on to the network thru the WEP encryption function. All points in the Wireless Network system have to have the same key shared which is set with a maximum of 32 alphanumeric characters. WEP Key Setting: This setting key is to configure the WEP encryption in the wireless network system. To generate the key, please insert the same PassPhrase in the field and click the Done to create the encryption key which must be same as the every points on the Wireless Network system. Then Click the Apply to store the setting keys. Wireless Cable Modem User s Manual 15

Wireless Settings Beacon Interval: The Beacon Interval specifies the duration between the beacon packets. The AP shall periodically transmit special frames called beacons that contain information for synchronization between the participating stations. The range for the Beacon Interval is between 20-1000 with a typical value of 100. RTS Threshold: The value should remain on its default setting 2432 bytes. If you encounter any date flow, only minor modifications are recommended. Fragmentation Threshold: The value indicates how much of the network resources devoted to recovering packet errors. The value should remain at its default setting of 2432 bytes. If you have decreased this value and experience high packet error rates, you can increase it again, but will likely decrease overall network performance. Authentication Type: It can be selected for Open System, Shared Key or Both for the indication of an authentication algorithm. Shared Key is to be selected while the WEP for PC card and Access Point are both enabled and setup with the same passphrase key. And Open System is for disabled WEP in Wireless Network system. DTIM Interval: DTIM is always a multiple of the beacon Period and determines how often a beacon contains a Delivery Traffic Indicator Message (DTIM). This message informs stations in power-save mode that a packet is waiting for them. Suggested value is 2. Preamble Type: There is the Long or Short selection to ensure that systems receiving the information correctly interpret when the data transmission starts. To select long Preamble may be used to minimize overhead and Long to maximize the network data throughput. The default value will be set for Long. Basic Rate: The basic transfer rate is to set based on the speed of the wireless network system. For slower network system is to be selected 1-2 Mbps and faster network 1-2-5.5-11 Mbps. Auto Rate Fall Back setting allows you to have flexible automatic data rate adjustment according to the connection situation. 18 Wireless Cable Modem User s Manual
