access the wired network but cannot communicate with each other.

Figure 150 Basic Service Set

ESS

An Extended Service Set (ESS) consists of a series of overlapping BSSs, each

containing an access point, with each access point connected together by a wired

network. This wired connection between APs is called a Distribution System (DS).

This type of wireless LAN topology is called an Infrastructure WLAN. The Access

Points not only provide communication with the wired network but also mediate

wireless network traffic in the immediate neighborhood.

One of the LEDs does not behave as expected. 24.2 NBG-417N Access and Login I dont know the IP address of my NBG-417N. I forgot the password. I cannot see or access the Login screen in the Web Configurator. I can see the Login screen, but I cannot log in to the NBG-417N. 24.3 Internet Access I cannot access the Internet. The Internet connection is slow or intermittent. 24.4 Resetting the NBG-417N to Its Factory Defaults You will lose all of your changes when you push the RESET button. 24.5 Wireless Router/AP Troubleshooting I cannot access the NBG-417N or ping any computer from the WLAN (wireless AP or router). I set up URL keyword blocking, but I can still access a website that should be blocked. I can access the Internet, but I cannot open my network folders. I can access the Web Configurator after I switched to AP mode.
