Troubleshooting for Wireless Networking
Robert J. Bartz · 2017
This chapter examines common problems associated with standards-based IEEE 802.11 wireless networking, how to identify problems based on the symptoms, and how to determine whether they are global affecting many or isolated affecting an individual. A first step in troubleshooting WLAN problems is to identify whether an issue is global or isolated. Global issues often include wired and wireless infrastructure devices and components. A receiver collects the propagated signal from the air using an antenna and reverses the process by transforming the received signal back into an alternating current signal. Through the use of a demodulation process, the digital data is recovered. The modulation or demodulation technology used depends on the wireless standard or amendment with which the device is compliant. The Microsoft Windows built-in wireless client utility is a very popular client utility for connecting to IEEE 802.11 wireless networks. The Microsoft Windows WLAN AutoConfig service runs as a service or background process in the Microsoft Windows operating systems.
