Slow Wi-Fi: Common Causes and Fixes

Experiencing a sluggish and unstable wi-fi? Don’t worry, you are not alone. It is not rare nowadays for users nowadays to find their Wi-Fi speed suddenly become slow. There are many causes that can lead to slow Wi-Fi, but in most cases, you can fix it by yourself.

I have collected some of the most common issues and how to deal with them.

Too Many Wi-Fi connecting Devices in Your Home

There are many smart devices today that rely on a Wi-Fi connection to works such as smart home bulbs, surveillance cameras, smart power outlets, or smart vacuums. As they all use your Wi-Fi at the same time, it may slow down quite significantly. In fact, a lot of old Wi-Fi routers are not designed to handle too many connected devices at the same time.

Solution: If possible, upgrade your Wi-fi router to the newest models for more compatibility with your smart devices. In addition, you should disconnect the currently not-in-use devices to improve your speed.

Wi-Fi Signal Encountered Too many obstacles

Multiple factors affect your internet speed, including your router’s location. Wifi routers nowadays typically transmit both types of signals at a frequency of 2.4 GHz and faster speeds at 5 GHz. A common Wi-fi speed-up trick is to connect to the 5 GHz frequency signals only. However, this trick sometimes won’t work properly if you are in a closed room or too far from the router. This is due to the fact that 5GHz frequency grants better wi-fi speed, but the signal cannot go too far or through too many obstacles like thick walls like the 2.4 GHz signals. So if you notice that your wi-fi speed becomes slow, your device is probably connecting to a 2.4Ghz signal.

Solution: You need to place your router in an open area where there is no obstacle blocking the signal. This will optimize the connection to your devices. To do this, you can check out this guide.

Background Programs

There are a lot of background programs that can take up the internet bandwidth and slow down your wi-fi speed. Windows Updates is one of the signature examples, it normally takes up your internet bandwidth for downloading updates in the background

Solution: Stop these background applications from running. On Windows, you can use the Task Manager to check if any program is using too many resources and stop them. For macOS users, you can use the Activity Monitor to do the same thing.

Malware

Malware and viruses from different sources can infect your computers and smartphones in many ways. They will either damage your device or steal personal data and send it to their server without you knowing about. This also consumes a lot of your bandwidth and dramatically reduces your Wi-Fi speed.

Solution: Use antivirus software to scan your devices and eliminate all the malware. In fact, users should establish themselves a habit of installing additional security applications, regularly updating the database, and scanning the entire device on a weekly basis.

There you go, these are the most common issues that lead to a slow Wi-Fi that I found. Personally, I hate it when my Wi-Fi becomes sluggish as I spend most of my time in the internet a day. But these fixes actually worked for me. That’s why I recommend them to all of you out there.
