Cannot access
the G-4100 v2
from the LAN. Check the cable connection between the G-4100 v2 and your computer or switch. Refer to
section
1 for details.
Ping the G-4100 v2 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 G-4100 v2’s.
In the computer, click Start, (All) Programs, Accessories and then Command Prompt. In
the Command Prompt window, type "ping" followed by the G-4100 v2’s LAN IP address
(192.168.1.1 is the default) and then press [ENTER]. The G-4100 v2 should reply.
If you’ve forgotten the G-4100 v2’s IP address or 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 G-4100 v2 to the factory defaults (password is 1234, LAN IP address 192.168.1.1
etc.; see your User’s Guide for details).
Cannot get a WAN
IP address from
the ISP. Check your Internet connection settings in the wizard (refer to section 3 ). Make sure that you
have entered the Internet access information correctly. With PPPoE or PPTP, the username
and password are case sensitive.
Cannot access
the Internet. Check the G-4100 v2’s connection to the Ethernet jack with Internet access. Make sure the
Internet gateway device (such as a DSL modem) is working properly.
For wireless clients, check that both the G-4100 v2 and wireless client(s) are using the same
ESSID, channel and WPA or WEP keys (if encryption is activated).
