|
|
RTS/CTS | Use RTS/CTS to reduce data collisions on the wireless network if you have wireless |
Threshold | 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. |
| Enter a value between 0 and 2432. |
|
|
Fragmentation | This is the maximum data fragment size that can be sent. Enter a value between |
Threshold | 256 and 2432. |
|
|
Output Power | Set the output power of the ZyXEL Device in this field. This control changes the |
| strength of the ZyXEL Device's antenna gain or transmission power. Antenna gain |
| is the increase in coverage. Higher antenna gain improves the range of the signal |
| for better communications. If there is a high density of APs within an area, decrease |
| the output power of the ZyXEL Device to reduce interference with other APs. |
| The options are Maximum, Middle and Minimum. |
|
|
Preamble | Select Long preamble if you are unsure what preamble mode the wireless adapters |
| support, and to provide more reliable communications in busy wireless networks. |
| Select Short preamble if you are sure the wireless adapters support it, and to |
| provide more efficient communications. |
| Select Dynamic to have the ZyXEL Device automatically use short preamble when |
| wireless adapters support it, otherwise the ZyXEL Device uses long preamble. |
|
|
802.11 Mode | Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to |
| associate with the ZyXEL Device. |
| Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to |
| associate with the ZyXEL Device. |
| Select Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN |
| devices to associate with the ZyXEL Device. The transmission rate of your ZyXEL |
| Device might be reduced. |
