A hands-on course focusing on the technical support of WiFi. Wireless LANs are often seen as simple communications that are simply installed and then left alone to work. This course ensures that delegates will be able to install WiFi networks which work but also enable the delegates to troubleshoot WiFi when it does go wrong.
