• Select Router if your device routes traffic between a local network and 

another network such as the Internet. 

• Select Access Point if your device bridges traffic between clients on the 

same network. 

If the problem continues, contact your ISP.

I cannot access the Internet anymore. I had access to the Internet (with the 
NBG4615), but my Internet connection is not available anymore.

Check the hardware connections, and make sure the LEDs are behaving as 
expected. See the Quick Start Guide and 

Reboot the NBG4615.

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 NBG4615 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 NBG4615 
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 NBG4615.

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.
