If the problem continues, contact your ISP. 

The Internet connection is slow or intermittent.

There might be a lot of traffic on the network. Look at the LEDs, and check 

. If the NBG-416N is sending or receiving a lot of information, try 

closing some programs that use the Internet, especially peer-to-peer applications.

Check the signal strength. If the signal strength is low, try moving the NBG-416N 
closer to the AP if possible, and look around to see if there are any devices that 
might be interfering with the wireless network (for example, microwaves, other 
wireless networks, and so on).

Reboot the NBG-416N.

If the problem continues, contact the network administrator or vendor, or try one 
of the advanced suggestions.

• Check the settings for QoS. If it is disabled, you might consider activating it.

1234. You have to make all of your changes again.

You will lose all of your changes when you push the RESET button.
