Why is my Wifi Slow?

Why-is-my-Wifi-Slow


Fast Wi-Fi is more important than ever. Either you need it for work purposes or just streaming the latest show on Netflix or watching last night NBA highlights on Youtube. Sluggish Wi-Fi can be frustrating coupled with eternal loading screens and the buffering of video and audio. This situation can be confusing as there are multiple reasons why your Wi-Fi may be working on a speed slower than intended. It could be the strength of the Wi-Fi, your device or router, the wireless channel, or even the network itself. In this article, we’ll be looking at what may be causing your slow Wi-Fi.

Why is Your Wi-Fi slow?

There can be several factors slowing down your Wi-Fi speed. We will look into them one by one to understand and fix those. Here are the most common problems that slows down the Wi-Fi.

1. Your frequency band

Frequency bands affect how fast and how far data can travel over Wi-Fi. There are two main frequency bands: 2.4 GHz (gigahertz) and 5 GHz. The 2.4 GHz frequency band gives you slower speeds at a longer distance while the 5 GHz frequency band gives you faster speeds at a shorter distance. 5 GHz band is the way to go for faster Wi-Fi, but with multiple devices on one band, this will make your Wi-Fi speed slow.

2. Your device is far from your Wi-Fi router/modem

Wi-Fi signal comes from the router. The greater the distance between the router and your device, the weaker the signal and this makes the Wi-Fi speed slower. The weak signal will negatively affect your device’s performance. This scenario is usually a problem associated with big homes. For bigger homes, you’ll need a Wi-Fi extender to increase the Wi-Fi coverage.

3. Presence of Blockers

Blockers block or interrupt Wi-Fi signals from passing through. Placing the router behind cabinets or walls provides an obstacle for the Wi-Fi signals. Wi-Fi signals have a hard time passing through metals, cement, or concrete. The more the obstacles, the weaker the signal gets. Similarly, microwaves and other devices that run on the same 2.4 GHz frequency as your Wi-Fi network can cause the Wi-Fi speed to reduce if these devices are nearby.

4. The strain on the bandwidth usage

Bandwidth is the highest rate of data transfer across a given path. You may be sharing the Wi-Fi connection with other people such as friends, roommates, or family members.  How many Wi-Fi devices do they own – smartphones, laptops, tablets, video games, etc? Moreover, they may be taking part in bandwidth-consuming activities such as playing online video games, streaming Netflix, or downloading huge files. These actions can greatly put a strain on the bandwidth and reduce your Wi-Fi speed. There’s also a chance a background program/app is using your bandwidth without your knowledge. For example, Windows Update is a notorious culprit that downloads updates in the background. Some apps hog the connection and slow the Wi-Fi speed. They constantly refresh or continuously use data in the background

5. Out-of-date routers

Your Slow Wi-Fi can be as a result of using an out-of-date router. Older routers may not have the latest standards or provide dual-band support for 2.4 GHz and 5 GHz. Newer routers provide much better connectivity and broad range compared to older routers. Out-of-date routers may not support bandwidth-preserving features or automatic channel switching.

6. Interference

Old routers that use only the 2.4GHz frequency band are susceptible to Wi-Fi interference. Bluetooth devices, microwave ovens use the same 2.4 GHz frequency range which can cause overlapping of Wi-Fi. As a result, this will cause interference between two routers broadcasting on the same channel and frequency. This can be a problem in apartments or buildings with many routers nearby.

7. Slow internet connection

If you have a slow internet connection coming to the Wi-Fi router, it is obvious that you are going to get slow data flow to your Wi-Fi devices. So make sure that your internet connection does not have any issues and works as expected. Even though you have stable, fast internet, at times due to various problems, it can get slow. So, run an internet speed test to make sure everything is working perfectly and the issue is something else.

This article has provided information on different issues that may cause your slow Wi-Fi speed. Once you can identify the problem, you’re halfway there in solving the problem.
