what's the difference between 802.11 b g n
Whats the difference between 802.11 a/b/g/n and WiFi things? You can connect to any hotspot that is unsecured or if you have the encryption key. Not all coffeee shops allow free WiFi (wireless) access. Right now most laptops will ship with 802.11g adapters.hats the diff between a WiFi card and a regular wireless card that has 802.11 written on it along with letters like a/b/g/n. i tried on wikipedia, but wikipedia doesnt do comparasion, only shows a lot of info i dont need for each card.
