Permit traffic exchange between wireless client stations
Enable this option to allow wireless client stations to exchange data with one another.
By default, the CN3000 blocks all traffic between wireless client stations.
Operating frequency

Radio

Select the frequency the CN3000 will operate at. The frequencies that are available are
determined by the radio installed in the CN3000 and the regulations that apply in your
country.
For optimum performance, choose a frequency that differs from other wireless access
points operating in neighboring cells by at least 25 MHz. Consult the Wireless >
Neighborhood page to view a list of access points currently operating in your area.
Distance between access points
Use this parameter to adjust the receiver sensitivity of the CN3000. This parameter
should only be changed if:
• you have more than one wireless access point installed in your location
• you are experiencing throughput problems
In all other cases, use the default setting of Large.
If you have installed multiple CN3000s, reducing the receiver sensitivity of the CN3000
from its maximum will help to reduce the amount of crosstalk between the wireless
stations to better support roaming clients. By reducing the receiver sensitivity, client
stations will be more likely to connect with the nearest access point.
RTS threshold
Use this parameter to control collisions on the link that can reduce throughput. If the
Status > Wireless page shows increasing values for Tx multiple retry frames or Tx
single retry frames, you should adjust this value until the errors clear up. Start with a
value of 1024 and then decrease to 512 until errors are reduced or eliminated. Note that
using a small value for RTS threshold can affect throughput. Range: 128 and 1540.
If a packet is larger than the threshold, the CN3000 will hold it and issue a request to
send (RTS) message to the client station. Only when the client station replies with a
clear to send (CTS) message will the CN3000 send the packet. Packets smaller than the
threshold are transmitted without this handshake.
Transmit power
Use this parameter to set the maximum transmission power of the wireless radio. The
following settings are available:
• HIGH: Sets the maximum transmission power the wireless card is capable of. It will be
• MEDIUM - 50mW (17dBm)
• LOW - 20mW (13dBm)
IP address

Wireless port

Specify the IP address you want to assign to the wireless port. By default, this is
192.168.1.1.
Note: Changing the IP address of the wireless port will cause you to lose contact with
the management tool. To reconnect, restart your computer or release/renew your IP
address, and enter the new address into your browser.
Note: If wireless client stations are currently using the CN3000, changing the IP
address will cause them to lose their connections. To reconnect, each client must reboot
or release/renew its IP address.
