Field | Description |
|
|
Beacon Interval | Beacon frames are transmitted by an access point at regular intervals to |
| announce the existence of the wireless network. The default behavior is to |
| send a beacon frame once every 100 milliseconds (or 10 per second). |
| The Beacon Interval value is set in milliseconds. Type a value from 20 to |
| 2000. |
|
|
DTIM Period | The Delivery Traffic Information Map (DTIM) message is an element included |
| in some Beacon frames. It indicates which client stations, currently sleeping |
| in |
| The DTIM period you specify here indicates how often the clients served by |
| this access point should check for buffered data still on the AP awaiting |
| pickup. |
| The measurement is in beacons. For example, if you set this to “1” clients |
| will check for buffered data on the AP at every beacon. If you set this to “2”, |
| clients will check on every other beacon. If you set this to 10, clients will check |
| on every 10th beacon. |

Fragmentation | Specify a number between 256 and 2,346 to set the frame size threshold |
Threshold | in bytes. |
| The fragmentation threshold is a way of limiting the size of packets (frames) |
| transmitted over the network. If a packet exceeds the fragmentation threshold |
| set here, the fragmentation function will be activated and the packet will be |
| sent as multiple 802.11 frames. |
| If the packet being transmitted is equal to or less than the threshold, |
| fragmentation will not be used. |
| Setting the threshold to the largest value (2,346 bytes) effectively disables |
| fragmentation. |
| Fragmentation involves more overhead both because of the extra work of |
| dividing up and reassembling of frames it requires, and because it increases |
| message traffic on the network. However, fragmentation can help improve |
| network performance and reliability if correctly configured. |
| Sending smaller frames (by using lower fragmentation threshold) may help |
| with some interference problems, such as with microwave ovens. |
| By default, fragmentation is off. We recommend not using fragmentation |
| unless you suspect radio interference. The additional headers applied to |
| each fragment increase the overhead on the network and can greatly reduce |
| throughput. |
