Section 1.3 on page 14

If the NBG-418N v2 is sending or receiving a lot of information, try closing some programs that use
the Internet, especially peer-to-peer applications.

2

Check the signal strength. If the signal strength is low, try moving the NBG-418N v2 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).

3

Reboot the NBG-418N v2.

4

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