Make sure that you have the correct power adaptor 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 Connections section for
details.
Ping the Prestige from a computer on the LAN. Make sure your
computer Ethernet adapter is installed and functioning properly.
If the LAN LEDs are all off, check the cable connections between
the Prestige and your computers on the LAN.
Verify that the IP address, 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 user ID, check your service type, user name,
and password in the WAN Setup screen.
Verify the Internet connection settings in the WAN Setup screen.
Make sure you entered the correct user name and password.
