To maintain wireless association, the WLAN service area on a bridge and the
device with which it is associated must match exactly. Therefore, if the bridge
is set to specify the WLAN service area and you change the other device’s
WLAN service area, make sure to change the bridge WLAN service area also.
■ Access Point Privacy Mode—This mode only applies when the network
mode is Access Point (Infrastructure) and should only be used when access
points are set with privacy enabled. (On 3Com access points, privacy is
enabled when the Broadcast WLAN Service Area Name (ESSID) mode is
disabled.) Click On to associate with access points set with privacy mode
enabled. Click Off to associate with access points set with privacy mode
disabled. When privacy mode is on, you must specify a Wireless LAN Service
Area, which must match the access point service area exactly.
■ Channel Selection—When the network mode is Access Point (Infrastructure),
this option is set to Automatically select the best channel, and cannot be
changed. In this case, the bridge uses the channel that the access point
is using.
When the network mode is Ad-hoc (Peer-to-Peer) you can specify channel
selection as follows:
■ Automatically select the best channel—When this option is enabled,
the bridge scans the primary channels. If the bridge is establishing a new
ad hoc network, it chooses the channel with the least number of packets.
If the bridge is joining an existing ad hoc network, it selects the channel
in use.
■ Specify the channel to use—To establish the channel for an ad hoc
network, select this option on the first bridge and choose a channel from
the Channel list. On the second bridge, set the channel selection to match
the first bridge.
■ Country Selection (Outdoor Bridge only)—Select the country from the
pull-down list. The highest allowable power level is automatically set.
■ Antenna Selection (Indoor Bridge only)—When you select a valid country,
antenna, and cable combination, the highest allowable power level is set
automatically.
Select the country from the pull-down list.
Click the radio buttons next to the antenna and cable being used.
Antenna model 3CWE496 (18 dBi) is not available in some countries. In the
United States, use of channels 12 and 13 in conjunction with model
3CWE496 is not allowed. The following table summarizes these and other
FCC regulations require that in the United States, use of channels 12 and 13 in
conjunction with an 18 dBi antenna is allowed only at very reduced power,
which the 3Com bridge sets automatically.
