What is WPA-PSK?
WPA-PSK means Wi-Fi Protected Access - Pre-Shared Key. It is an enhanced wireless
encryption standards defined by the Wi-Fi Alliance.
What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the
manufacturer to any Ethernet networking device that allows the network to identify it at the
hardware level. For all practical purposes, this number is usually permanent. Unlike IP
addresses, which can change every time a computer logs onto the network, the MAC
address of a device stays the same, making it a valuable identifier for the network.
How do I resolve issues with signal loss?
Connectivity can change depending on the device’s environment. Such materials as lead
glass, metal, concrete floors, water and walls can inhibit the signal and reduce range. Try
using a Wi-Fi channel with less traffic in order to eliminate interference. For more
