Speed of connection: The 802.11b and 802.11g standards will
automatically choose the best speed depending on the quality of your
connection. As the signal quality weakens then the speed falls back to
a lower speed. The speeds supported by 802.11g are 54 Mbps,
48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, and 6 Mbps. The
speeds supported by 802.11b are 11 Mbps, 5.5 Mbps, 2 Mbps and
1 Mbps. Note that when an 802.11g client is connected to an
802.11b Access Point, it will only operate at the 802.11b supported
speeds. In general the closer you are to the Gateway the better the
speed. If you are not achieving the speed you had anticipated then try
moving the antenna on the Gateway or moving the Wireless
computer closer to the Gateway. In an ideal network the Gateway
should be located in the centre of the network with Wireless
computers distributed around it. Applications are generally available
with the computer wireless card to carry out a site survey. Use this
application to find the optimal siting for your wireless computer.
Consult your Computer Card documentation and vendor for more
details.

continuously, this indicates that the software has detected a possible
fault with the hardware. Remove power from the Gateway, wait 10
seconds and then re-apply power. If the Alert LED comes on
continuously again, then a fault has been detected. Locate the copy of
the Gateway software on the accompanying CD-ROM or 3Com web
site (

this clears the fault (refer to "Recovering from Corrupted Software"
below). If this does not fix the problem, contact your supplier for
further advice.
During normal operation, you may notice the Alert LED lighting briefly
from time to time. This indicates that the Gateway has detected a
hacker attack from the Internet and has prevented it from harming
your network. You need take no specific action on this, unless you
decide that these attacks are happening frequently in which case you
