5 things that will reduce the speed of the Wi-Fi network, will reduce the wi-fi5

By using the old protocol, overlapping channels, and low data rates, Wi-Fi networks may become slower. The following describes how to solve these and other performance problems.

Wi-Fi (Wireless LAN) is quite easy to change. Competition between Wi-Fi devices and dynamic communication media of radio waves makes them a sensitive technology, with many settings and circumstances reducing the speed.

Faster Wi-Fi is always better without high-bandwidth devices and applications.

The following are some unavoidable things that may reduce the wi-fi speed:

1. Use older wireless and Security Protocols

Using older security protocols on a Wi-Fi network significantly reduces performance. This is irrelevant to the highest support standard of the Access Point and its commitment. For example, the 802.11ac standard can support data rates that exceed 1, 000Mbps. However, If WEP or WPA security is configured, the data rate is limited to 54 Mbps. This restriction is due to the security types of encryption methods using the temporary Key Integrity Protocol (TKIP.

Therefore, to ensure that the old Wi-Fi security method does not reduce the network speed, use Advanced Encryption Standard (AES) to enable WPA2-only security. Do not select the WPA/WPA2 hybrid mode or WPA2-TKIP.

If an older Wi-Fi client does not support WPA2-AES security, check whether there are firmware updates with this feature added. Next, consider adding a USB or PCI-based Wi-Fi adapter to a computer or device to provide it with modern Wi-Fi connections. If these adapters are not supported, consider using a wireless bridge that also has an Ethernet connection. Consider using the old protocol enabled by the old version to create a separate SSID, or completely replace the old Wi-Fi client device.

2. 5 GHz band

There are 11 channels in the GHz band (North America), but only three non-overlapping channels can be provided when the default 20 MHz band is used. If the 40 MHz band is used, only one channel is provided. Because the adjacent AP is located on different non-overlapping channels, the GHz band may become very small quickly.

However, the 5 GHz band provides up to 24 channels. Not all access points (APS) Support all channels, but if 20 MHz wide channels are used, all channels do not overlap. Even with a 40 MHz channel, up to 12 non-overlapping channels can be created. Therefore, in this frequency band, the same frequency interference between the AP and any other adjacent networks is less likely.

Organizations should try to use as many Wi-Fi clients as possible to use 5 GHz frequencies in the Network to increase speed and performance. Consider upgrading any GHz Wi-Fi client to a dual-band client. In addition, the use of any frequency band steering function on the Access Point (AP) can increase the opportunity for dual-band clients to connect to 5 GHz access instead of 2 to 4 GHz. If the Organization has full control over the Wi-Fi client and is sure that its 5 GHz coverage is good, you can even check whether 2.4 GHz can be disabled on the client.

3. incorrectly set the Access Point (AP) Channel

Because the 2.4GHz frequency band is so crowded, channels used by Access Points of the Organization are crucial. It is easy to interfere with the same frequency from neighboring networks or even their own access points (APS. For this lower frequency band, try to use non-overlapping and 11 channels with 20 MHz band width. Although most access points (APS) and wireless controllers have automatic channel functions, they sometimes do not work properly. Carefully check the automatic channel allocation to see if they make sense. If they do not make sense, you can set your own channels.

When verifying automatic channel assignment or manually setting them, it is best to find the plan at the location of the identified access point (AP. In this way, the Access Point (AP) location can be visualized and the channel allocation can be written. If there are more than three access points (APS), the channels and 11 must be reused. However, we try to set it to keep access points (APS) that are set to the same channel away from each other as much as possible. For example, if you have six access points evenly distributed along a long corridor, set the Access Point channels in sequence. Do not forget any other level of buildings, and minimize the number of access points (AP) with the same channel ).

4. Low Data Rate

The Access Point (AP) can control the data rate connected to the Wi-Fi client. When the Access Point (AP) supports the lowest data rate, this means that they will accept slow or poor connections. Although wireless access points that do not support the lowest data rate will discard the Wi-Fi client more quickly, this is usually what organizations want. The organization does not want the Wi-Fi client to maintain a connection with the AP when the connection speed is too slow, because it will reduce the overall performance of the network. If the Wi-Fi network is correctly designed and well covered, you can expect the Wi-Fi client to roam to the optimal access point (AP) as quickly as possible ), rather than sticking to the access point (AP) that provides slow connections ).

Most enterprise-level access points (APS) provide control over the exact rate of enabled data. If possible, disable the minimum data rate: 1-12 Mbps. If you have a high-density network with a wide coverage range, consider disabling a higher rate, or even up to 54 Mbps.

5. Lack of design and Configuration

Poor overall wireless design and/or configuration may cause Wi-Fi performance problems. Professional wireless field surveys should be conducted to determine the location of the appropriate access point (AP), and post-installation surveys should be conducted to verify the correct coverage. Any major physical changes to buildings and/or la s should also be adjusted.

If you do not use tools such as Airmagnet or Ekahau for map-based website surveys, it is difficult to visualize the coverage to detect any coverage vulnerabilities. The survey tool also helps identify the same channel interference and helps set the correct channel allocation. And do not just design the network, throughput, and user density based on the coverage scope.
