[Tips] Some tips to speed up the most effective WiFi connection

Welcome back to this series of articles on WiFi networks. In the last article, what factors will affect the speed of your WiFi network? I have presented in detail the factors that can affect the speed of WiFi network connection.

Today, in the final article of the Series, we will find a solution to overcome those factors for the smoothest Internet experience.

I. Physical measures to speed up WiFi

Yes, and below I will list some of the best solutions that you can apply. In addition to the ways I presented in this tutorial, if you still have any effective methods that you have applied successfully, do not forget to share your experience with others to learn.

#first. Put the Router in a convenient location

As I mentioned in the previous article, the space between the WiFi router and your access device plays a decisive role in the quality of the wave.

So any obstructions should be minimized on the transmission line. For the best coverage and strongest signal strength, you should place your WiFi transmitter in a high position, away from walls and large metal objects. It is recommended to place the transmitter on the stand and without obstructions in the upper and lower parts.

#2. Avoid other broadcast devices causing interference

In particular, you should stay away from microwaves because as you know, microwave radiation also has a 2.4 GHz frequency, similar to most WiFi waves and with its very strong wave intensity, even if it only leaks a little May cause heavy interference to the WiFi signal.

In addition, devices using Bluetooth connectivity such as wireless keyboards and mice or other transmitters should also be located at a distance of several meters to avoid interference with each other.

# 3. Antenna

Antenna design (also known as antennae) WiFi transmitters are usually straight bars and waves are most strongly transmitted on a plane perpendicular to the Antenna.

So if you want to increase the coverage area and signal strength horizontally, you can leave these antennas vertically. On the other hand, if you want to broadcast to other floors of the house, setting up a horizontal Antenna will increase the signal strength vertically.

# 4. Use specialized equipment

However, no matter how good your WiFi transmitter is, with an area too large to cover, it is inevitable that the signal strength will be reduced.

Now the most effective measure is to use the device to expand coverage (WiFi Extender), range extender (WiFi Repeater) or increase signal (WiFi Booster).

Especially the WiFi Mesh solution on modern devices today can give you a seamless experience without having to reconnect every time you move to the coverage area of ​​other APs in the network.

II. The software solutions to speed up WiFi connection

After all, the aforementioned hardware measures aren't always easy to take.

Because even if you can optimize your home space, there are still many other sources of interference around, such as neighboring WiFi, especially in urban areas. Now we need to find other 'soft' solutions that are more complex but often work very well.

#first. Choose the most suitable wave channel

As mentioned in the previous post, the 2.4 GHz band for the WiFi network is divided into 14 different wave channels (with channel 14 disabled in most countries). It will be difficult to avoid the channel of every other router in your area, but we can look for an optimal channel with the least interference to set up our router.

There are actually a few tricks to help you trick your router into thinking that the area you live in is Japan, where the 14th wave channel is allowed and you can use this channel.

Using channel 14 ensures bandwidth disputes are minimal, however not countries ban this channel for fun, so it is better not to do so to avoid causing trouble for yourself and others. Here's how to find the optimal wave channel for you. Proceed as follows:

+ Step 1: On Windows operating system, press Windows + R, in the Run dialog box, type cmd.exe => and press Enter to open Command Prompt.

+ Step 2: Enter the following command, and press Enter:

netsh wlan show networks mode = bssid

A list of WiFi networks in the area will be displayed with their respective channels and signal strength.

In my area there are 3 networks with channels 3,6 and 11. Only these 3 networks overlap all the 13 available WiFi channels! There seems to be no independent channel option that completely avoids interference.

However, if you look closely, there are two networks with channels 3 and 11 with very high signal strength (99%) and must be avoided as far as possible.

Channel 6 has a relatively low 20% signal strength, so the effect will be lower. Therefore, the most likely option at this time is one of channels 1, 13, 5, 7. You can consider choosing appropriate for your surroundings, with the principle of avoiding channels with overlap. High numbers and strong wave intensity as far as possible.

+ Step 3: The last step is to set up the radio channel settings on the Router. Here I will demonstrate how to set up on the transmitter is a Tp-link WDR 4300 Router that supports 802.11n WiFi and dual band WiFi Dual Band.

Log in to the router settings page by going to 192.168.1.1 (may differ depending on the device) in your browser. Then enter the username and Password (default admin-admin on TP-Link router, you find it on the back of the Router).

At the Wireless tab (or Wireless 2.4GHz with a router that supports dual-band) you select Wireless Setting and go to the Channel option, then select the appropriate channel. Click Save to save your changes.

#2. 'Dodging' the 2.4 GHz crowded lane

If really 'on the same road' with the above method and bored with the chaos of 2.4 GHz band usage, the simplest and most effective way is to move to a new, more spacious lane that is not yet available. Many participants: 5GHz band.

Although theoretically the most popular WiFi standard available on most devices today is that 802.11n supports both 5GHz and 2.4GHz (WiFi Dual Band) bands. But on the hardware side, to implement this method, 5GHz support is required on both the receiver and the broadcasting equipment. Proceed as follows:

+ Step 1: Continue at the Router configuration page, if the device supports WiFi Dual Band, the menu on the left hand side of the screen will have the option of Dual Band Selection and Wireless 5 GHz.

Step 2: Click Dual Band Selection and tick Concurrently with 2.4GHz and 5GHz (802.11a / b / g / n) to enable both bands (recommended) or 1 of the other two options if only one is enabled. in two bands of 2.4 GHz and 5 GHz

Step 3: Select the Wireless 5GHz tab and configure as normal the network parameters, so the SSID is the same as the 2.4GHz network configured earlier with the extension of the corresponding frequency for easy identification.

After pressing save, a new network with your name will appear and be accessible on devices supporting 5GHz WiFi.

Some note:

1. Advantages: This method can significantly increase the theoretical WiFi network speed because the 5GHz band has wider bandwidth, higher frequency, non-overlapping wave channels like 2.4GHz and less interference. from other devices. However, the speed to whichever speed depends on the bandwidth limit of your Internet package.
2. Disadvantage: The transmission distance is shortened compared to the 2.4GHz band, consumes energy of the transceiver and less supported devices at the present time.
3. So it's ideal to turn on both bands (Dual Band mode) to both work with older devices and optimize the experience.

# 3. Firmware upgrade for Router

New firmware versions always contain security updates that make devices safer against cyber attacks. Besides, there are code and algorithm updates that increase the performance of the router device. So spending a little time checking and updating regularly will help your Router run stable at the highest speed.

For tp-link router, log in to the device as above and access the tab System Tools => Firmware Upgrade to check the Firmware version.

Then go to the homepage tp-link.com to find your device model, if there is a newer update, download and extract it if necessary.

At the Firmware Upgrade page just click Browse and point to the downloaded file, then click Upgrade and the installation will take place automatically.

# 4. Distribution of bandwidth for devices

In fact, the demand for using Internet on devices is very diverse and has different priorities.

For example, if you are downloading a movie from Google Drive on your PC and playing Lien Quan at the same time on your Smartphone, the movie download process will always utilize the maximum possible bandwidth to increase download speed, accidentally causing 'lag' for the road. Smartphone transmission makes the gaming experience extremely uncomfortable.

Obviously the first priority is the fight to get good results, so we will limit the bandwidth of the PC so that it does not affect the bandwidth of the Smartphone.

First of all, you refer to this article to know how to set up static IP for your PC. Then on the Router you login as above and find the tab Bandwidth Control or IP QoS depending on the device.

Under Control Setting, check the option Enable Bandwidth Control, set the total upload bandwidth (Egress Bandwidth) and the maximum and minimum total download bandwidth (Ingress bandwidth) for the router, set these values ​​higher than the bandwidth. Update your Internet plan to avoid restrictions.

At Rules List, click Add New to set up a bandwidth rule. Enter IP Range as the static IP you have set up for your PC or group of devices to limit bandwidth.

Then set the minimum and maximum bandwidth to be less than the total bandwidth set so that the remaining bandwidth of the line is large enough for other needs like gaming (usually a few Mbps is sufficient). Then click Save to save the changes.

III. Conclude

Okay, above are some of the most effective solutions to speed up Wifi connection that you can apply.
