Chapter 26 Troubleshooting

NBG-419N v2 User’s Guide

Make sure you allow the Router to be remotely accessed through the WLAN interface. Check your 
remote management settings.

• See the chapter on Wireless LAN in the User’s Guide for more information.

I set up URL keyword blocking, but I can still access a website that should be blocked.

Make sure that you select the Enable URL Keyword Blocking check box in the Content Filtering 
screen. Make sure that the keywords that you type are listed in the Keyword List. 

If a keyword that is listed in the Keyword List is not blocked when it is found in a URL, customize 
the keyword blocking using commands. See the Customizing Keyword Blocking URL Checking 
section in the Content Filter chapter.

I can access the Web Configurator after I switched to AP mode.

When you change from router mode to AP mode, your computer must have an IP address in the 
range between “192.168.1.3” and “192.168.1.254”.

Refer to 

 for instructions on how to change your computer’s IP address.

I cannot access or see a USB device that is connected to the Router.

Disconnect the problematic USB device, then reconnect it to the Router.

Ensure that the USB device in question has power.

Check your cable connections.

Restart the Router by disconnecting the power and then reconnecting it.

If the USB device requires a special driver, install the driver from the installation disc that came 
with the device. After driver installation, reconnect the USB device to the Router and try to connect 
to it again with your computer.

If the problem persists, contact your vendor.

I cannot install the ZyXEL Share Center Utility.
