Netcomm 3G Wireless Router User N3G005W User Manual

N3G005W

This section provides an overview of common issues, 

and possible solutions for the installation and operation 

of the N3G005W Wireless Router.

1. 

Unable to access the Web Configuration 

when I use my computer to configure 

the router.

Note: 

It is recommended that you use an Ethernet connection to 
configure the N3G005W. 

Ensure that the LAN light on the N3G005W Wireless 

router is ON.
If the light is NOT ON, check to see if the cable for the 

Ethernet connection is securely connected.

Note:  

Ensure that the IP Address of the computer is in the same 
range and subnet as the N3G005W Wireless Router. 
The default IP Address of the N3G005Wireless Router is 
192.168.123.254. All the computers on the local area 
network must have a unique IP Address within the same 
range (e.g., 192.168.123.x). All computers must also have 
the same subnet mask (e.g., 255.255.255.0).

Do a Ping test to make sure that the N3G005W Wireless 

Router is responding.

• 

Click on Start > Run

• 

Type in CMD and press Enter.

• 

Type “ping 192.168.123.254” (without quotes). 

A successful ping will shows four replies.

Note:  

If you have changed the default IP Address, ensure you ping 
the correct IP Address assigned to the N3G005W.

2. 

Why my wireless client can NOT access 

the Internet?

When the N3G005W Wireless Router is configured to 

use Wireless encryption (WEP, WPA/WPA2 etc), you 

need to ensure your wireless adapter settings match 

the router settings. Please refer to your wireless adapter 

manual for more info. Ensure that the wireless client is 

associated and joined with the correct Access Point.
To check this connection (Windows XP), follow these steps:

• 

Click on Start > Control Panel > Network 

Connection

• 

Right Click on Wireless Network connection

• 

Select View Available Wireless Networks. The 

Connect to Wireless Network screen appears. 

Ensure you have selected the correct wireless 

network.

Ensure the IP Address assigned to the wireless adapter 

is within the same subnet as the Access Point and 

gateway. The N3G005W Wireless Router has a default 

IP Address of 192.168.123.254. Wireless adapters 

must have an IP Address in the same range (e.g., 

192.168.123.x). Although the subnet mask must be 

the same for all the computers on the network, no two 

devices may have the same IP Address. Therefore, each 

device must have a unique IP Address.
To check the IP Address assigned to the wireless 

adapter, follow the steps below:

• 

Click on Start > Run

• 

Type in CMD and press Enter.

• 

Type in “ipconfig /all”  and press Enter

• 

Type in “ping 192.168.123.254” to check if 

you can access the N3G005W

Note:  

If you have changed the default IP Address, ensure you ping 
the correct IP Address assigned to the N3G005W.
