HITRON CGN2 USER'S GUIDE
Use this field to control how the CGN2 sends
acknowledgement (ACK) requests in IEEE 802.11n
transmissions.
Normally, an ACK request is sent after every data or
management frame in order to ensure that it has been
received correctly. However, when you enable Auto
Block ACK the CGN2 sends a burst of multiple frames
together, and follows it with a single, block ACK request.
Select Disable to not use block ACKs.

Select Enable to use block ACKs.

NOTE: Block ACK can increase your network's speed,
as fewer ACK messages are sent. However, you
should not use it if your network is prone to
interference, since if the transmitting station
needs to retransmit information, the required
retransmission will be much longer.
Use this field to control how the CGN2 receives
acknowledgement (ACK) requests in IEEE 802.11n
transmissions.
Select Disable to accept block ACK requests. The
transmitting device may then send multiple data frames
together, followed by the block ACK request.
Select Enable to decline block ACK requests. The
transmitting device must then follow each data frame
with an ACK request in the traditional manner.
Select the number of 802.11n radio transmitting
channels (1 or 2) for High Throughput (HT) transmission.
Select the number of 802.11n radio receiving channels
