Start Guide.

client are the same as the settings in the AP.

I cannot access the Internet anymore. I had access to the Internet (with the NBG4615), 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 1.5 on page 22.
2 Reboot the NBG4615.
3 If the problem continues, contact your ISP.
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 1.5 on page 22.
If the NBG4615 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 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).
