To turn off the access point DHCP server capability regardless of whether or not 
another DHCP server is available, click Disable and click Save.
Gateways—You can specify up to three additional gateway IP addresses. 
These settings are optional. (Only the default gateway is required).

Properties
The Data Transmission Properties page lets you select radio channel settings and 
performance settings. This page contains a link to the Advanced Settings page, 
where you can set additional data transmission properties.
Clear Channel Select—Lets the access point find a channel automatically.
When this option is enabled, the access point scans the primary channels to 
determine the traffic on those channels and chooses the channel with the least 
number of packets.
By default, the access point automatically selects the optimal channel for 
wireless transmissions. The access point will select between channels 1–13. If 
your network supports clients that do not acknowledge 13 channels, you will 
have to manually select a channel within the reach of those clients. For 
example, if you have clients that only support channels 1–11, you must 
manually set the access point to use a specific channel in that range.
If France, you must manually select from channels 10–13.
To select a specific channel, click the off (Specify the channel) button and 
choose a channel from the Channel list. 
Network Traffic Accelerator—To increase performance, click On (enhanced 
performance). If you experience problems when equipment other than 3Com 
11 Mbps Wireless LAN equipment is being used, click Off.
Data Preamble—To increase performance, click Short (enhanced 
performance). When equipment that does not support short preamble is also 
being used, click Long.
Data Rate—These settings configure the data rates used for wireless 
transmissions. By default, the access point selects the best data rate for the 
current connection.
If “Automatically set the best data rate” is selected, the Data Rate cannot be 
selected manually.
If “Manually set the data rate” is selected, the 5.5Mbps and 11Mpbs options 
become active. You may not alter the settings for the 1Mbps and 2Mbps rates 
since these rates must always be available to transmit certain types of wireless 
traffic.
The data rates may either be Required or Optional. When the data rate is set to 
Optional, the AP determines if it is appropriate to use that data rate or if the 
signal strength requires a lower data rate to be used. If the data rate is set to 
Required, the AP does not have the option to modulate to a lower data rate, 
and may lose connection with clients that cannot support the higher data rate.
Beacon Period—The beacon period sets the amount of time between 
beacons sent out from the AP. Normally you will not have to change this 
setting, although it can be useful in extremely noisy RF environments.
Radio Antenna—These settings determine whether the radio will use one or 
two antennas. If the user attaches an external antenna, this parameter should
