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

. If the N4100 is sending or receiving a lot of information, try 

closing some programs that use the Internet, especially peer-to-peer applications. 

If you are accessing the Internet wirelessly, check the signal strength. If the signal 
strength is low, try moving your computer closer to the N4100 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).

Turn the N4100 off and on. 

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

I cannot access the N4100 or ping any computer from the WLAN.
