Objective
The Advanced Wireless Settings is configured to enable advanced wireless functions for the device. The basic settings must be configured before the advanced setup is made. The advanced settings can only be configured if the Network Mode on the Basic Wireless Settings page is not set to disabled. To configure the basic wireless settings on SRP520, refer to the article Configure Basic Wireless Settings on SRP520.
The objective of this document is to show you how to configure Advanced Wireless Settings on SRP521W and SRP527W Services Ready Platforms.
Applicable Devices
• SRP527W
• SRP521W
Software Version
• 1.01.27(007)
Advanced Wireless Settings
Step 1. Log into the Services Ready Platforms Configuration Utility and choose Interface Setup > Wi-Fi Settings > Advanced Wireless Settings. The Advanced Wireless page opens:
Step 2. Choose an SSID from the Select a SSID drop-down list to configure its corresponding wireless network’s advanced settings.
Step 3. Enter a value in the RTS Threshold field. The SRP sends Request to Send (RTS) frames to a receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. The value entered in this field is the limit for the size of these RTS frames; the default is 2347.
Step 4. Click the radio button Enabled in the AP Isolation field to use AP Isolation. AP Isolation isolates all wireless clients and wireless devices from one another. Wireless devices will be able to communicate with the SRP but not with other wireless devices on the network. AP Isolation is disabled by default.
Step 5. Basic Rate — Series of rates at which the SRP can transmit. The SRP advertises its Basic Rate to the other wireless devices in your network, so they know which rates will be used and automatically selects the best rate for transmission. The default setting is Default, which allows the SRP to transmit at all standard wireless rates (1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). From the Basic Rate drop down list, other options are 1-2Mbps, for use with older wireless technology, and All, which allows the SRP to transmit at all wireless rates. The Basic Rate is not the actual rate of data transmission. If you want to specify the SRP’s rate of data transmission, configure the Transmission Rate setting.
Step 6. Depending on the speed of your Wireless-N network, set the data transmission rate from the N Transmission Rate drop-down list, or select Auto for the SRP to automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback negotiates the best possible connection speed between the SRP and a wireless client. The default option is Auto.
Step 7. Depending on the speed of your Wireless-N network, set the data transmission rate from the Transmission Rate drop-down list, or select Auto for the SRP to automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback negotiates the best possible connection speed between the SRP and a wireless client. The default is Auto.
Step 8. Select an option from the CTS Protection Mode drop-down list. This feature is used when your Wireless-N and Wireless-G products are experiencing severe problems and are not able to transmit to the SRP in an environment with heavy 802.11b traffic. This function boosts the SRP’s ability to catch all Wireless-N and Wireless-G transmissions but can impact performance. The default option is Auto.
Step 9. Enter a value within the range (1 - 255) in the DTIM Interval field. This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the SRP has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with the DTIM Interval value. Clients hear the beacons and wake up to receive the broadcast and multicast messages. The default value is 1.
Step 10. Enter a value between 256 - 2346 in the Fragmentation Threshold field. This value specifies the maximum size for a packet before data is fragmented into multiple packets. In most cases, it should remain at its default value of 2346.
Step 11. Enter a value between 40 and 3500 milliseconds in the Beacon Interval field. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the SRP to synchronize the wireless network. The default value is 100.
Step 12. Choose high, middle, or low to specify the range of the wireless network from the Power Control drop-down list. The default is high, which is a normal power level.
Step 13. Click Submit to save your settings.
