If you are trying to access the Internet wirelessly, make sure the wireless settings in the wireless 
client are the same as the settings in the AP.

Disconnect all the cables from your device, and follow the directions in the Quick Start Guide again. 

Go to Maintenance > Sys OP Mode > General. Check your System Operation Mode setting. 

If the problem continues, contact your ISP.

If the NBG-418N v2 is sending or receiving a lot of information, try closing some programs that use

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).

Reboot the NBG-418N v2.

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

If you reset the NBG-418N v2, you lose all of the changes you have made. The NBG-418N v2 re-
loads its default settings, and the username/password resets to admin/1234. You have to make all 
of your changes again.
