Comment 1 for bug 1637126

Some notes on terminology: At some point "Wireless" must have been changed to "Wi-Fi" in the GUI but the desktop help wasn't changed. I briefly checked terminology outside Ubuntu. For example, Wikipedia uses "Wi-Fi" not "WiFi" or "wifi" or "wi-fi". I haven't done a global replace in the help of "wireless" to "Wi-Fi" since terms such as "wireless card" or "wireless network" seem to be widely used outside Ubuntu. I think any occurrences of "wi-fi" etc in the help should be changed to "Wi-Fi". Let's be consistent.
