Flashcards in Network+ Chapter 12 Deck (20):
If you cannot connect to an AP and you've verified that your DHCP configuration and WEP key are correct. What would check next to get the AP working?
check the MAC address filtering on the AP
Why was Carrier Sense Multiple Access w/ Collision Avoidance created?
to solve problems within the RF spectrum.
what is the benefit of WPA over a static WEP key?
WPA can change dynamically while the system is used.
which employs multiple transmitters and receiver antennas to increase data throughput.
multiple-input, multiple-output (MIMO)
several antennae over several paths and are then recombined by another set of antennae to optimize throughput and multipath resistance
is the simplest of all IEEE 802.11 networks in that no network infrastructure is required.
