2.4 GHz Radio Advanced Settings

The 2.4 GHz Radio Advanced settings allow you to fine-tune wireless performance beyond the basic configuration. These options help you adjust broadcast behavior, transmission parameters, power usage, and client limits to optimize coverage and reliability in your 2.4 GHz network.

To configure 2.4 GHz Radio Advanced Settings

1. Navigate to DEVICE | Internal Wireless > Settings > 2.4GHz Radio Advanced.

2. In the Beacon Interval (milliseconds) field, specify how often the access point sends beacon frames. Decreasing the interval makes passive scanning more reliable and faster because the network is announced more frequently. The default interval is 200 milliseconds.

3. Turn on the Enable Green AP button to increase power efficiency. This setting is disabled by default.

4. In the Green AP Timeout(s) field, enter the number of seconds to wait after no clients are associated before the access point enters power‑saving mode. The range is 20 to 65,535 seconds. The default is 20 seconds.

5. From the Transmit Power drop‑down menu, select one of the following:

   • Full – Sends the strongest signal on the WLAN. For example, use Full Power for building‑to‑building connections.

   • Half (‑3 dB) – Recommended for office‑to‑office communication within a building.

   • Quarter (‑6 dB) – Recommended for shorter‑distance communication.

   • Eighth (‑9 dB) – Recommended for shorter‑distance communication.

   • Minimum – Recommended for very short‑distance communication.

6. From the Preamble Length drop‑down menu, select Short or Long. Short is recommended for efficiency and improved throughput on the wireless network, but it is not supported by 802.11b. The default is Long.

7. In the RTS Threshold (bytes) field, specify the request‑to‑send (RTS) threshold. The minimum value is 1, the maximum is 2,347, and the default is 2,346.

   This field sets the threshold for the packet size (in bytes) at which an RTS is sent before transmission. Sending an RTS helps prevent wireless collisions when clients are within range of the same access point but not within range of each other. If network throughput is slow or if many frame retransmissions occur, decrease the RTS threshold to enable RTS clearing.

8. In the DTIM Interval field, specify the DTIM (Delivery Traffic Indication Message) interval. The valid range is 1–256, and the default value is 1.

   For 802.11 power‑save mode clients that receive multicast traffic, the DTIM interval determines how many beacon frames the client waits before a DTIM is sent. Increasing the DTIM interval can help improve power efficiency for these clients.

9. In the Association Timeout (seconds) field, enter the number of seconds for client association. The default value is 300 seconds, and the allowed range is 60–36,000 seconds.

   If your network is experiencing heavy traffic, you can increase the timeout by specifying a higher value in this field.

10. In the Maximum Client Associations field, enter the maximum number of client associations allowed for each access point that uses this profile. The minimum value is 1, the maximum is 128, and the default is 128. This setting limits the number of wireless stations that can connect at the same time.

11. From the Data Rate drop-down menu, select the speed at which data is transmitted and received. When set to Best, the device automatically selects the optimal data rate based on interference and other environmental factors.

    You can also manually choose a data rate from the available options, which range from 1 Mbps to 54 Mbps.

12. Click Accept.
