Troubleshooting
This chapter offers some suggestions to solve problems you might encounter.
• You can also refer to the logs (see
• For the order in which the USG applies its features and checks, see
.
None of the LEDs turn on.
Make sure that you have the power cord connected to the USG and plugged in to an appropriate
power source. Make sure you have the USG turned on. 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.
Cannot access the USG from the LAN.
• Check the cable connection between the USG and your computer or switch.
• Ping the USG from a LAN computer. Make sure your computer’s Ethernet card is installed and
functioning properly. Also make sure that its IP address is in the same subnet as the USG’s.
• In the computer, click
Start
,
(All) Programs
,
Accessories
and then
Command Prompt
. In
the
Command Prompt
window, type "ping" followed by the USG’s LAN IP address (192.168.1.1
is the default) and then press [ENTER]. The USG should reply.
• If you’ve forgotten the USG’s password, use the
RESET
button. Press the button in for about 5
seconds (or until the
PWR
LED starts to blink), then release it. It returns the USG to the factory
defaults (password is 1234, LAN IP address 192.168.1.1 etc.; see your User’s Guide for details).
• If you’ve forgotten the USG’s IP address, you can use the commands through the console port to
check it. Connect your computer to the
CONSOLE
port using a console cable. Your computer
should have a terminal emulation communications program (such as HyperTerminal) set to
VT100 terminal emulation, no parity, 8 data bits, 1 stop bit, no flow control and 115200 bps port
speed.
I cannot access the Internet.
• Check the USG’s connection to the Ethernet jack with Internet access. Make sure the Internet
gateway device (such as a DSL modem) is working properly.
• Check the WAN interface's status in the
Dashboard
. Use the installation setup wizard again and
make sure that you enter the correct settings. Use the same case as provided by your ISP.
