Table 10 Troubleshooting
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 Connections section for details.
Ping the Prestige from a LAN computer. 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
LAN computers.
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 screen.
Verify the Internet connection settings in the WAN screen.
Make sure you entered the correct user name and password.
For wireless clients, check that both the Prestige and wireless client(s) are using the
same ESSID, channel and WEP keys (if WEP encryption is activated).
