ESSID
Extended Service Set ID. The ESSID is the identifying name of a wireless network - strictly it is the identifying name of a
wireless access point. It allows one wireless network to be clearly distinguishable from another. The default ESSID is autonet-
XXXX, where XXXX is the last 4 digits of the In-Car Router’s serial number. It is recommended that you keep this ESSID in
order to distinguish your router from other routers that may be in the area.
WEP key
The WEP key is not shown if it is set. You do not have to set it, if you want it to remain the same. To set the current encryption
key, just enter the key in hex digits as XXXXXXXXXX. The key must be 10 hex digits, (e.G. 1234567890 ) You can also enter
the key as an ASCII string by using the s: prefix. The ASCII string must be five characters, (e.g. s:smile ). To disable WEP, enter
“off” as the WEP key.
Radio Mode
This allows you to select whether the radio is in 802.11b, 802.11g and 802.11a mode. Not all routers support all modes, so
only the supported modes for your In-Car Router are shown.
Channel
Direct communication between an 802.11 Radio card and an access point occurs over a common channel frequency. The
FCC allows channels 1 through 11 within the U.S. An important concept to note regarding channel assignments is that the
channel actually represents the center frequency that the transceiver within the radio and access point uses (e.g., 2.412 GHz
for channel 1 and 2.417 GHz for channel 2). There is only 5 MHz separation between the center frequencies, and an 802.11b
signal occupies approximately 30 MHz of the frequency spectrum. The signal falls within about 15 MHz of each side of the
center frequency. As a result, an 802.11b signal overlaps with several adjacent channel frequencies. This leaves you with only
three channels (channels 1, 6, and 11 for the U.S.) That you can use without causing interference between access points.
