Ten ways to increase the signal of wifi

increase the signal of wifi

Fixing wireless network performance issues can be a daunting task. There are only two important factors that should be considered before anything else, the area covered by the waves and the speed of data transmission in this area. The coordination and compatibility of each of these two factors with each other will play a decisive role in increasing the efficiency of your wireless network. 
For example, having a super-fast wireless network is great, but if that speed is only achieved if your laptop is right next to the router, that speed is no longer worth it. You also need to strengthen the signal sending and receiving range. On the other hand, if you have trouble opening a photo and this is done slowly even though you are in the same room as the router, now you have to go to the speed problem.

In general, each of these problems will negatively affect the performance of your entire network. In addition to the need for high-speed data exchange, you will also need a wider range of router signals. There are several factors that can affect both functions.

Distance is one of the most important factors that negatively affects the performance of wireless networks, your room at home or at work may be far from where the wireless router is located. Even the location of the source to the destination of sending and receiving signals is effective in this regard. If there are several obstacles or mazes between you and the wireless device, they can be problematic (although the technology used in the new routers, known as beamforming, helps the router signal The most direct way to reach the destination).

Wave interference is another important factor that affects the performance of your wireless network. If you live in an apartment, the waves sent from your neighbor router can have a negative effect on your router waves. Your indoor equipment may also affect your transmissions. If your washing machine, hair dryer, cordless phone and microwave oven are placed between your router and laptop, they may affect your wireless network waves.

The problem may be with the software you use. Routers, like any other device, need firmware updates; Even if you just bought it. Software updates usually improve hardware performance as well.

These are just some of the reasons why your wireless network can send and receive signals. Fortunately, there are many ways to increase the signal strength of wireless networks, and most of them can be done with some simple changes and settings, and others require the provision of peripherals. Here are ten useful and efficient ways to troubleshoot your wireless network:

1- Change the channel

 WiFi routers work on private channels. When you normally install a router, the device usually selects a specific channel by default. Some routers automatically select more private channels, but your device may not have this feature. To boost the router’s signal performance and range, it’s best to find the most secluded Wi-Fi channel available. A good piece of software called insider There is for this purpose. Do not worry about charts and additional information. What you need to pay attention to is the Channel column. Note that in the image below, several routers in this range use Channel 6. If your router is set to the same channel, you need to change it to the most private channel available. To change the channel, you can refer to the interface of your router. Each router uses its own method to access the user interface. For this reason, you should refer to the manufacturer’s guide to access it.

2. Update your router firmware

Home router firmware updates are often overlooked by home users. Commercial network devices usually display the news to the user when new software is ready for the device, but conventional wireless routers, especially older models, usually do not have such an option for notification. . 

Check from time to time if an updated version of your router’s firmware has been released. There is usually a section for updating the firmware in the router interface. But it is better to visit the website of your router manufacturer a few times and search for the firmware you want (most manufacturers allow you to search for the firmware) and then upload it through the router interface. . Usually when the updated version of the firmware is released, information is also provided about which of the device fixes this update.

3. Update your network card firmware

Like routers, network cards installed on a computer or laptop need to upgrade their firmware. Keep in mind that achieving an acceptable signal range and good performance on a wireless network depends not only on the router but also on the network card installed in the guest device (other factors also play a role, but These are the two most important). Most laptops use network cards embedded in them. To specify the name of the card used on your laptop, go to the Network Settings section (via the Control Panel in the Windows operating system), and after specifying the card manufacturer, go to its website and make sure you are using the latest firmware version.

4- Change the position of the router

If your problem is the range of the signal range, change the location of the router. Your router does not need to be close to your modem (unless you use a separate modem and router). Ideally, the WiFi router should be located in the center of the access point so that all guest devices can have relatively the same signal strength. To get the router away from the modem, you can get Ethernet Cat 5 cable of your desired length from network equipment stores.


Adventurers may want to try DD-WRT, an open source software for routers that enhances its performance and capabilities on routers. Not all routers currently support it, but the number of supported routers is increasing. Note that installing DD-WRT may void your router warranty. After you install DD-WRT, some other manufacturers will not help you with any problems with the router, so use it for routers that are still under warranty or in commercial networks. It is used, not recommended. In addition, there is no guarantee that a router will not have a negative impact after the updated versions of the DD-WRT are released. However, many users use it as a free method to manipulate their routers.Check the DD-WRT site  to see if it supports your router. Also note that on some routers, removing the DD-WRT and returning to the original state will not be easy, and you will have to spend a lot of time and search to return to the first state. 

6- Use the second router as an access point or repeater

You can use almost any router as an access point. To do this, you must connect the LAN port of the second router to the LAN port of the main router. If the IP address of your primary router is and its netmask is, you can set the IP address of the second router to and use the same netmask. In addition, it is important to use the same SSID and security settings on the second router and turn off DHCP on the second router.

New routers have made this process easier. If your second router is only one year old, it probably has settings that can be set to access point or repeater. These settings can be done with just a simple click of a button in the user interface. For more information on this, visit the router manufacturer’s website or its manual. You can also buy a dedicated access point (although it costs more) to avoid network configuration difficulties. If you are planning to do this, it is better that your access point and your router are both from the same manufacturer.

7- Antenna

Many newer 802.11n Wi-Fi routers typically use internal antennas, but there are still others that also support external antennas and can be replaced with more powerful models. Hawking Technology offers an example of these amplified antennas called HAI15SC Hi-Gain Wireless Corner Antenna . Hawking claims that this antenna increases your wireless signal strength from 2dBi to 15dBi. Antennas like this can be connected to most routers that support an external antenna connector. High-quality signal amplification antennas usually cost between $ 40 and $ 100.

8- Repeaters and Extenders

Most wireless device manufacturers offer devices that act as repeaters and amplifiers of Wi-Fi waves. These types of devices sometimes interfere with the waves and are usually expensive. Note that these two devices should not be considered the same. A repeater repeats the existing wireless network, meaning that the encryption type and SSID are repeated, so you do not need to log in to another Wi-Fi network. An Extender extends the current network using a separate SSID, and you need separate login information to connect to it. Expanders are more common these days. Two useful and efficient examples of them are D-Link’s Wi-Fi Dual Band Range Extender  and Amped Wireless’ High Power 700mW Dual Band AC Wi-Fi Range Extender .

9- New router and network card

Perhaps the easiest way to increase signal strength and improve performance on a wireless network is to get a new router and network card at the same time. The current standard for 802.11n and 802.11ac routers is dual-band. Dual-band hardware is ideal because the 5 GHz band provides a significant improvement in performance. The 2.4 GHz band is said to cover a wider range of signal transmissions than the 5 GHz band, but it is also more crowded, which has a negative effect on the performance of the 2.4 GHz band. . The number of routers using the latest 802.11.ac wireless networking standard is increasing day by day. These routers can provide up to one gigabit per second of throughput. But to access that speed, your network receiver must also support the 802.11ac standard. This latest generation of router technology is also the most expensive type of hardware. If cost is not your concern and you are using devices that support the 802.11ac standard, you should go for the 802.11ac standard. These routers are also compatible with older WiFi hardware such as the 802.11n / b / g standard.

10- Integration

Although, according to the manufacturers themselves, their products are compatible with the products of other manufacturers and work well, but it is clear that products produced by the same manufacturer are more compatible with each other. If possible, try to get your network devices from a single manufacturer. This includes not only the router and network card, but also the antenna, repeater / extender, and access points.
