Prestige 334 Quick Start Guide
Make sure that you have the correct power adapter connected to the Prestige and plugged in
to an appropriate power source. Check all cable connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you should
contact your local vendor.
Check the cable connection between the Prestige and your computer or hub. Refer to the
Rear Panel section for details.
Ping the Prestige from a LAN computer. Make sure your computer Ethernet card is installed
and functioning properly.
If the 10/100M LAN LEDs are off, check the cable connections between the Prestige and
your LAN computers.
Verify that the IP address and subnet mask of the Prestige and the LAN computers are in the
same IP address range.
The WAN IP is provided after the ISP verifies the MAC address, host name or user ID.
Find out the verification method used by your ISP and configure the corresponding fields.
If the ISP checks the WAN MAC address, you should clone the MAC address from a LAN
computer. Click WAN and then the MAC tab, select Spoof this Computer's MAC address -
IP Address and enter the IP address of the computer on the LAN whose MAC address you
are cloning.
If the ISP checks the host name, enter your computer's name (refer to the Wizard Setup
section in the User's Guide) in the System Name field in the first screen of the WIZARD.
If the ISP checks the user ID, click WAN and then the ISP tab. Check your service type, user
name, and password.
Check the Prestige's connection to the cable/DSL device.
Check whether your cable/DSL device requires a crossover or straight-through cable.
Click WAN to verify your settings.
