WiFi suddenly slows down? The best ways to fix slow WiFi speeds

There are many reasons why your WiFi can be slow. It could be a compulsion to ignore WiFi, a wireless channel, a computer or router, or even a problem with the network itself. With so many factors affecting your Wi-Fi speed, it can be a bit difficult to identify the problem and fix it. But there’s always a way, right? If your WiFi is suddenly slow and you can’t find the problem, we’re here to help you find the problem and fix it.

Since there are many factors that affect the speed of your Wi-Fi network, we’ll start with basic issues and move on to more advanced issues to fix them.

1. Restart the router

The popular device reboot fix works in many situations and can also be a fix for slow WiFi. All you need to do is turn off the router for 10-15 seconds and turn it back on. Most routers have an on/off switch on the back, but you can also unplug the power adapter to cut power and turn it off. After restarting, close it (wait at least 1 minute), try to use it again and see if the problem is still there.

While you’re at it, restart the device you’re using WiFi on. Sometimes the cause can be a device connected to WiFi.

2. Check other devices using WiFi

The total bandwidth of the WiFi network is shared between the devices currently connected to it, and any high-bandwidth program running on one device will affect the Internet speed of other devices. Usually, tasks like web browsing don’t have much impact, but if someone is playing games or streaming video or downloading huge files on the device, it can drastically affect the network bandwidth of other devices. So make sure no one is using your Wi-Fi for high-bandwidth content.

What’s more, you can disconnect idle devices like smartphones that aren’t in use because background apps can still use bandwidth even when the screen is off.

3. Stop background programs with bandwidth

There is a possibility that a background program is using your bandwidth without your knowledge. For example, Windows Update is known to download updates in the background, and there are other programs that are connected to the Internet and download bandwidth in the background; even malware can do this!

If you are using a Windows computer, you can see active background processes from the Windows Task Manager. Press Ctrl + Shift + Esc to open task manager and go to tab ” Processes Both Windows and third-party software are listed here. Now look for third party apps that are not running and click on “ Finish the process ” when selected. Just try to avoid closing the process with words like Windows, Microsoft, explorer.exe, and system, etc. If you suspect a process, you should look it up online and see what it’s doing.

You should also get a good antivirus program to make sure there is no malware lurking in the background.

4. Add protection to your WiFi

If no programs or devices are using your bandwidth, there may be a possibility that your neighbor is stealing your bandwidth. If your WiFi is not secure enough or not secured at all, someone can connect to it and use your bandwidth. you should use WPA2 securitybecause it is currently the most advanced WiFi security protocol. You will need to change the password from the router’s main interface, which you can access by entering the router’s IP address into your browser’s address bar.

Find IP address of the routerpress the button Windows + R and enter ” cmd ” in the Run window to open a command prompt.

Get in here” ipconfig ” and press enter and you should see the IP address next to “Default Gateway”. Just type this address in your browser’s address bar and press enter. When prompted for a password, type “Admin” or “12345”. If both don’t work, try contacting your ISP and request your password.

The interface is different for each router, so we cannot give you exact instructions. However, you should find an option to change your password under Security, Wireless or similar. Just choose WPA2 security and AES encryption, then use a strong password.

5. Location of your device and router

The location of the router plays a very important role in ensuring that Wi-Fi signals reach devices correctly and offer optimal speed. Wi-Fi signals are sent in a dome, and any obstacle between the router and the device can affect the speed. If you want to send signals all over your home, it’s best to place them in a central location and at a higher point. However, what will be the focus of objects between the device and the Wi-Fi signal.

While Wi-Fi signals can easily penetrate most objects with little or no drop in speed, they do certain objects that are very difficult or impossible to penetrate with Wi-Fi signals . For example, Wi-Fi signals have a hard time penetrating metals, cement or concrete, so if you are behind a wall with such material, it will affect Wi-Fi signals. Moreover, microwave ovens and cordless phones operate on almost the same frequency as Wi-Fi (ie 2.450 GHz), so they also interfere with signals.

Also, the distance from the router also affects the Wi-Fi signal. The further you go, the weaker the signals will be. Try to stay within 6-10 meters.

6. Change the Wi-Fi channel

Wireless signals operate on different channels similar to radio signals, and all routers near your area are connected to these channels. If there are multiple routers connected to the same channel, they can interfere with each other’s signals. Fortunately, you can manually change this channel and choose one that has less load.

To that end, Nirsoft’s WifiInfoView is a great little tool that’s simple and free. After starting the program, all Wi-Fi channels and their number will be displayed. Here, choose the one that is least crowded and you are ready. You can also use Net Stumbler if WifiInfoView doesn’t work well for you.

7. Windows network adapter to save energy

If you put Windows into power saving mode to save power and extend battery life, there’s a good chance you’re also saving power on the network adapter. Windows can reduce the power of the network card to save energy and at the same time reduce the performance of the Internet. To set the maximum value go to control panel from the Start menu and click ” System and security “.

Then click ” Power options “then click” change plan settings ” next to the selected plan.

On the next screen, click ” Change advanced power settings ” and open the Power Options window. Here click ” Wireless adapter settings “and set” Maximum performance “.

8. Repair network drivers

Sometimes corrupted network drivers can cause the internet to slow down on this computer. To find and repair network drivers, press Window + R for open dialog window Jogging and enter ” devmgmt.msc “. Device manager will open, double click here ” Network cards ” and make sure everything is fine. A driver with a yellow triangle and an exclamation mark indicates that there is a problem in it . If you find it, right-click and then click ” Update the driver software Then follow the instructions in the software update wizard and it should be fixed.

If not fixed, you can also use Driver Booster to automatically repair and update all drivers.

9. Slow download speed

In case everything seems to be fine, but you’re experiencing slower speeds when downloading something specific, it’s probably not your internet’s fault. When you download something from anywhere, download speed depends on internet speed and download server capacity . Even if you have a fast internet connection, the download server must have enough capacity to allow you to take advantage of this speed. If this happens when downloading files from a specific website, try downloading files from different websites and see if there are any differences.

10. Do you use a VPN?

If you use a VPN to browse anonymously, you should know this all VPNs slow down to some extent internet speed . A VPN routes traffic through its servers and encrypts and decrypts data in real time. This leads to slower processing because the Internet needs more data. You will need to stop using VPN service or upgrade your internet speed package for better speed.

11. Reset your router

If all else fails, you can completely reset your router to factory settings, which should undo any bad changes that might be affecting your WiFi. To reset the router, you will find a small reset button in a hole directly on the router (usually on the back). You can use a paper clip to press this button. Press and hold this button for 10-15 seconds and the router should reboot, confirming that it has been reset. After doing this, you will need to redo all changes and set a new Wi-Fi password.

12. Contact your Internet service provider

If nothing works, you should contact your ISP and discuss the problem. Maybe the problem is on their end and they can provide proper instructions to solve the problem. Many times I was able to get help from a service representative who would personally check the system and fix it. You too can get this service if you ask for it and if your ISP cares enough.

Ready to fix WiFi speed issues

We’ve tried to cover some of the most common causes of slow WiFi and how to fix them. While there are many other reasons that can affect Wi-Fi performance, be sure to keep this in mind and share your feedback with us if the issue continues to occur.

Also, be aware that some ISPs throttle bandwidth during peak hours or other specific periods. If you experience a slowdown over a period of time, contact your ISP. They can help you otherwise you will have to change your ISP.
