Beacon Interval Best Settings For Better Speed


Beacon interval is the known router settings. It can help users to control the speed of wi-fi connection. The beacon is a timing frame sent periodically by the access point. It has the function to warn customers that the network is present, warn about frames recorded in the access point buffer and also synchronize the data transmission. By default, the beacon is transmitted every 100 milliseconds, but at most access points it is possible to specify any value between 10 and 1000 milliseconds.

Beacon interval

The 100 ms range used by default is a good cost/benefit, but when using the wireless network for games, or any activity where latency time is an essential factor, reducing the time to just 20 ms will give better results. A short interval can also help improve stability in noisy environments or the case of long-distance links.

What is Beacon interval?

Beacon is originally a broadcast packet which passed from our router. It synchronizes the wifi network system. Beacon interval needs the info of the router and other parameters. We all need to troubleshoot when our internet connection become slowly down. Sometimes, we need to unplug the router, change settings, and call ISP to solve technical issues and many more. There is another unknown fact that is known as beacon interval wifi adjustment.

Adjust Beacon interval wifi

The wifi beacon interval method is very simple. Keep the default settings 100ms, and it works fine many times. Adjust if you see severe speed drop in the router. The adjustment is necessary to keep setting in minimal condition. The default setting in Beacon interval wifi is 100ms. Sometimes it becomes lower 50ms or 75ms. It will help to connect the wifi signal without dropping any packets. It also depends on the battery life of the device.

RTS Threshold

This parameter indicates the packet size that a Request to Send (RTS, or send request) signal must use to send to the receiving wireless unit before the wireless transmitting unit opens the communications channel. The default value is already very good, but if we have more than 4 clients connected to the same router you can try to lower the threshold slightly (2306).

Adjusting the “RTS Threshold” can help with packet loss. This happens when a computer connected wirelessly can obtain an IP but cannot ping anywhere. Then reduces the “RTS Threshold” to a value that is not less than 2304/2306.

The RTS threshold is a mechanism used to prevent the collision of packets between devices that are not “seen” or that do not communicate directly with each other. To prevent this, the 802.11 wireless communication standard allows devices to use the RTS (Request To Send) | Ready To Send (ready to transmit)) and CTS (Clear To Send) flags as mechanisms to clean a space of time. The RTS flag is used to reserve the channel to transmit while silencing the other devices.

Wifi preamble mode

The Wifi preamble mode defines the size of the cyclic redundancy check block (CRC) of the packets. A set of data in the header of the packet used to determine if it has errors before sending it to the internet (if I discover it quickly an error.

I can also correct it quickly, and I avoid rejecting the package just when it arrives at the destination, several milliseconds later) with this I gain reliability in the transmission and streamline the communication. Virtually all devices support the Long Preamble option, and many support the Short Preamble option.

A short preamble allows greater network performance. Because it requires a smaller portion of the data packet occupied with control data, but as against some devices it does not support it. A long preamble is very compatible but less efficient. In the same compatibility plan, we will set this option to “Long.”

If problems are connecting to the router or staying connected to it, it may be necessary to adjust the Beacon Interval parameter to a lower value between 50 and 100 milliseconds. The ideal value is 75.

Beacon Interval

  • Access the settings of your wireless router.
  • Search for the Beacon Interval. By default, it comes with a value of 100. Change this value by putting it between 20 and 50 (I advise you to put in 20 because the smaller, the better).
  • Leave the Wi-Fi speed on the router in Mixed (b / g) or just B. Never use only in G. By following the steps above you will notice a significant improvement in the speed of your Wi-Fi connection!

Now you must be wondering … Why does this improve the speed of the connection?

Fragmentation length

Adjusting the “Fragmentation length” also helps with connection problems to the router when it is impossible to stay connected, and it is recommended that you reduce it to a value not less than 2304.

The Fragment length determines the maximum size of the packets that circulate through the wireless network. If the value is high, the packets will be larger. Therefore there will be less fragmentation.

Large packets mean higher performance of the network, (if we remember the packets had a header that are bytes occupied in data of addressing and control of errors, but not to transmit useful information, more packages means more bytes occupied in addressing and control of errors and not for useful transmission).

If the value is low, the packets will be smaller, so in the case that there is an error in the transmission, it will be easier to determine it and lower the number of bytes to be retransmitted, as counterpart we have less useful bandwidth.

Best beacon interval for gaming

I would also like to mention something about gaming. In my experience with Linksys equipment, this technology was only marketing since it allowed connections of more than 100 Mbps. The result in the real performance of the network was not what was expected.

There are even documented incompatibilities with gaming when using WDS from firmware such as dd-wrt. So be careful when using these technologies that magically give you more speed than the established standards. I do not believe in improvements such as Linksys SpeedBooster or 108G D-link.

Settings of the wireless network parameters

There are some tweaks to improve the connection, but first of all, it is recommended that you use the latest firmware version of the manufacturer or if you are using a third party firmware like the dd-wrt I recommend you are using a stable version. This is because many times the firmware updates include an updated driver for the wireless interface or adjustments to the wireless configuration in addition to solving other problems.

Adjust the parameters that we will describe below to obtain the maximum performance of our Wi-Fi network.

Archer c7 optimal setting

If you are using Archer c7, follow the optimal settings:

Open router panel with admin name and password. Go to the wireless setting of the c7 router. You can see 2.4 GHz and 5 GHz bandwidth option. I recommend using 2.4 GHz. Many devices don’t support 5 GHz. Save the settings and restart the router. Now, your Archer c7 is in an optimal setting.

Asus rt-ac88u optimal setting

The gigabit router has lots of pros. Login the router panel for the optimal setting. Select the wireless from the advanced setting. It is located on the left sidebar. Set the bandwidth 2.4 GHz. Don’t set the 5GHz. Set new SSID and save the settings. After restarting the router, you will see the change.

The interference

Interference is the biggest problem in wireless networks. Wireless networks transmit on certain channels, generally from 1 to 11 (this varies according to the regulations of each country) which represent a frequency in MegaHertz (MHz).

As you can see in this image, channels 1, 6 and 11 are highlighted with red, which are the only ones that do not interfere with each other and the most recommended using. For those who are in Europe, they can use channels 1, 7 and 13, the latter being the recommended one.

If there are two wireless networks located close to one another and transmitting on the same channel (or same frequency) what will be happening is that the two networks are interfering with each other.

Change insight value of Roaming Sensitivity Level

Changing the insight value can solve the Wi-Fi length problems on Windows 10. Follow the procedure:

  1. Press Win+X from the PC/Laptop keyboard.
  2. Choose the device manager from the list.
  3. Open it and select Wi-fi adapter.
  4. Now, go to Advanced tab and choose Roaming Sensitivity Level.
  5. Set transmit power as you need.
  6. Save the changes and restart your PC.

The change will affect.


In any case, we can increase this value of beacon interval to gain performance.If we continue to see problems of association, we can go down the times until we achieve a stable situation. It can also happen that a connected device loses synchrony and disconnects. For the moment, and as we intend to achieve a wireless connection to proof of errors, we are going to suppose a moderately contaminated situation.
