Chapter 8 Wireless Screen
Table 24 Wireless: Bridge / Repeater
LABEL | DESCRIPTIONS |
Disable channel | This field displays only when you select 802.11a or 802.11n/a in |
switching for DFS | the 802.11 Radio Mode field. Select this if you do not want to use |
| DFS (Dynamic Frequency Selection). |
| DFS (dynamic frequency selection) allows an AP to detect other |
| devices in the same channel. If there is another device using the |
| same channel, the AP changes to a different channel, so that it can |
| avoid interference with radar systems or other wireless networks. |
|

Super Mode | (For |
| Select this to improve data throughput on the WLAN by enabling fast |
| frame and packet bursting. |
|
|
Channel ID | Set the operating frequency/channel depending on your particular |
| region. |
| To manually set the NWA to use a channel, select a channel from the |
| |
| Usage tab to open the Channel Usage screen to make sure the |
| channel is not already used by another AP or independent |
| peer wireless network. |
| To have the NWA automatically select a channel, click Scan instead. |

unlock | Click this to disable DCS and select a channel ID manually. |
|
| Note: DCS is Disabled by default |
|
|
Short GI | This field is available only when 802.11n/g or 802.11n/a is |
| selected as the 802.11 Radio Mode. Select Enable to use Short |
| GI (Guard Interval). The guard interval is the gap introduced |
| between data transmission from users in order to reduce |
| interference. Reducing the GI increases data transfer rates but also |
| increases interference. Increasing the GI reduces data transfer rates |
| but also reduces interference. |
|
|
This field is available only when 802.11n/g or 802.11n/a is | |
Aggregation | selected as the 802.11 Radio Mode. Select Enable to allow the |
| grouping of several |
| into one large |
| function allows faster data transfer rates. |
|
|
RTS/CTS | Use RTS/CTS to reduce data collisions on the wireless network if you |
Threshold | have wireless clients that are associated with the same AP but out of |
| range of one another. When enabled, a wireless client sends an RTS |
| (Request To Send) and then waits for a CTS (Clear To Send) before |
| it transmits. This stops wireless clients from transmitting packets at |
| the same time (and causing data collisions). |
| A wireless client sends an RTS for all packets larger than the number |
| (of bytes) that you enter here. Set the RTS/CTS equal to or higher |
| than the fragmentation threshold to turn RTS/CTS off. |
|
|
Fragmentation | The threshold (number of bytes) for the fragmentation boundary for |
Threshold | directed messages. It is the maximum data fragment size that can |
| be sent. Enter an even number between 256 and 2346. |
