Troubleshooting
What's the difference between 802.11b, 802.11g, 802.11a,
and Pre-N?
Currently there are four levels of wireless networking standards, which
transmit data at very different maximum speeds. Each is based on the
designation for certifying network standards. The most common wireless
networking standard, 802.11b, transmits information at 11Mbps; 802.11a
and 802.11g work at 54Mbps; and Pre-N works at 108Mbps. Pre-N, the
precursor to the upcoming 802.11n release, promises speeds that exceed
802.11g, and up to twice the wireless coverage area. See the following
chart for more detailed information.
