MIMO stands for multiple input, multiple output. This wireless technology allows equipment to be used by several antennas to send and receive multiple data streams. MIMO can eliminate dead spots and improve range. To see the improvement, all the gadgets on the wireless network should support it. MIMO is at the heart a 802.11n, but other networking standards also use it.

Wi-Fi Protected Access 2, or WPA2, is the best and strongest form of encryption. Wi-Fi Protected Access, WPA, is acceptable, it is good. Wired Equivalent Privacy, or WEP, is simply not safe.
