save any changes made.

Select the protocol of the firewall port (All, TCP, UDP, or ICMP).

Enter the first port of the range that will be used for the firewall rule in the top port range field and enter the last port in the field

underneath.

Use the drop-down menu to schedule the time that the Firewall rule will be enabled. The schedule may be set to Always, which will

Section 3 - Configuration

Set the transmit power of the antennas.

Beacons are packets sent by an Access Point to

synchronize a wireless network. Specify a value. 100 is

the default setting and is recommended.

This value should remain at its default setting of 2346.

If inconsistent data flow is a problem, only a minor

modification should be made.

The fragmentation threshold, which is specified in bytes,

determines whether packets will be fragmented. Packets

exceeding the 2346 byte setting will be fragmented

before transmission. 2346 is the default setting.

(Delivery Traffic Indication Message) 1 is the default setting. A DTIM is a countdown informing clients of the next window for listening

to broadcast and multicast messages.

802.11n/b/g (2.4GHz)

Use the radio buttons to specify whether the Router should use the

Short Preamble

or

Long Preamble

type. The preamble type

defines the length of the CRC (Cyclic Redundancy Check) block for communication between the Router and roaming wireless adapters.

Use the drop-down menu to specify the wireless mode that will be used by the 2.4GHz band. The available options are

802.11n only,

802.11 Mixed (g/b),

and

802.11 Mixed (n/g/b)

.

Use the drop-down menu to select the channel bandwidth. If you selected the

802.11 Mixed (g/b)

or

802.11 Mixed (n/g/b)

wireless

mode, the available options are

20 MHz

and

20/40MHz

. If selecting the

802.11n only

wireless mode,

20MHz

is the only available option.

Check this box to reduce the guard interval time therefore increasing the data capacity. However, it’s less reliable and may create

higher data loss.
