TP-Link AX11000 Router

Wireless settings

WMM: The packets with high-priority messages being transmitted preferentially.
Wireless Multimedia Extensions (WME), also known as Wi-Fi Multimedia (WMM), is a Wi-Fi Alliance interoperability certification, based on the IEEE 802.11e standard. It provides basic Quality of service (QoS) features to IEEE 802.11 networks. WMM prioritizes traffic according to four Access Categories (AC): voice (AC_VO), video (AC_VI), best effort (AC_BE), and background (AC_BK). However, it does not provide guaranteed throughput. It is suitable for well-defined applications that require QoS, such as Voice over IP (VoIP) on Wi-Fi phones (VoWLAN).

Short GI: Increases the data capacity by reducing the guard interval time.
Short GI its Short Guard Interval, it means faster data rate (10 to 12% increase) because of better spectrum utilization and fastest packet speed. Short GI can be disabled to have better stability if there is interference or obstacles, Short GI is also associated with more CPU utilization.

AP isolation: This function isolates all connected wireless stations so that wireless stations cannot access each other through WLAN.
Wireless AP Isolation is a feature of some routers that prevents wireless devices from communicating with each other123. It can enhance network security by isolating potentially malicious traffic. Some routers have a Wireless isolation, AP Isolation, Station Isolation, or Client Isolation feature that allows you to lock down your Wi-Fi network. This feature is ideal for businesses with public Wi-Fi networks or anyone who’s just a bit paranoid. This feature confines and restricts clients connected to the Wi-Fi network.

Airtime Fairness: Improves the overall network performance by sacrificing a little bit of network time on your slow devices.
Airtime Fairness feature is based on TDMA technology, short for Time Division Multiple Access. It divides the Wi-Fi signal into many same time slots, and each Wi-Fi device takes turns to send or receive data from the Internet within its own time slot. In this way, the capacity and efficiency of Wi-Fi will be improved.

Zero Wait DFS: Zero Wait DFS (Dynamic Frequency Selection) allows the router to immediately reselect a new channel once the radar signal is detected on a channel allocated to radar devices to ensure lag-free network experience.
A mandate for radio systems operating in the 5 GHz band to identify and avoid interference with radar systems now supports zero-wait feature. When an 802.11 radio detects radar, it vacates its channel and switches to another channel.

Beacon Interval: Enter a value between 40 and 1000 in milliseconds to determine the duration between beacon packets that are broadcasted by the router to synchronize the wireless network. The default value is 100 milliseconds.

RTS Threshold: Enter a value between 1 and 2346 to determine the packet size of data transmission through the router. By default, the RTS (Request to Send) Threshold size is 2346. If the packet size is greater than the preset threshold, the router will send RTS frames to a particular receiving station and negotiate the sending of a data frame.
The threshold range is around 0 – 2347 bytes; if the packet transmitted by the access point is larger than the threshold, the RTS/CTS function will initiate. If the packet size is less than the threshold or below average, the function will not initiate. The recommended standard of the RTS threshold is around 500.

DTIM Interval: The value determines the interval of DTIM (Deliveray Traffic Indication Message). Enter a value between 1 and 15 intervals. The default value is 1, which indicates the DTIM Interval is the same as Beacon Interval.

Group Key Update Period: Enter a number of seconds (minimum 30) to control the time interval for the encryption key automatic renewal. The default value is 0, meaning no key renewal.
