wireless client are the same as the settings in the AP.
4 Disconnect all the cables from your device, and follow the directions in the Quick Start
Guide again.

V I cannot access the Internet anymore. I had access to the Internet (with the
NBG318S), but my Internet connection is not available anymore.
1 Check the hardware connections, and make sure the LEDs are behaving as expected. See
the Quick Start Guide and
Section 1.4 on page 33.
2 Reboot the NBG318S.
3 If the problem continues, contact your ISP.
V The Internet connection is slow or intermittent.
1 There might be a lot of traffic on the network. Look at the LEDs, and check Section 1.4
on page 33. If the NBG318S 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 NBG318S 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 NBG318S.
4 If the problem continues, contact the network administrator or vendor, or try one of the
advanced suggestions.
Advanced Suggestions
• Check the settings for bandwidth management. If it is disabled, you might consider
activating it. If it is enabled, you might consider changing the allocations.
