the G-4100 v2 

from the LAN.

Check the cable connection between the G-4100 v2 and your computer or switch. Refer to 

section

 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

 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

Check your Internet connection settings in the wizard (refer to section

). 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).
