Why is my computer so slow all of a sudden?

The process of testing wifi speed

The main network speed test goal is to measure three factors: ping rate, download speed, and upload speed. The measured results from these three factors will reflect how fast or slow the WiFi network is.

• Ping: This is a parameter that shows the latency of the network. The ping rate is the time it takes for a packet of data to be sent from one computer to another and then received a response back. The lower the ping speed, the stronger your WiFi network speed is.

Ping rate

• Download speed: Download speed is the speed at which data is downloaded from the network to your computer via the Internet, measured in Mbps.

• Upload speed: Upload speed, is also known as the speed of uploading data from your computer to the network. Currently, all WiFi networks use optical fiber, so the upload speed is usually equal to or not too much different from the download speed.

Regular network speed test ( via gospeedcheck.com, e.g.) helps you know how fast or slow the network speed is, especially for WiFi networks that have been used for a long time. This will help to quickly overcome if my wifi is slow all of a sudden so that there is no interruption to work and daily activities.

What makes wifi suddenly slow? 

If you’ve experienced slow WiFi speeds, it could be due to some of the reasons below:

Don’t restart the router for a long time

Since the wifi router is an electronic device, it can get hot so there could be a reason why is my wifi slow all of a sudden. 

Solution:

Restart your wifi router and modem. After restarting the modem and router, you should see a green light on the modem and the router will start flashing again and the speed should improve.

Restart your wifi router

Place the router so far

When you install the internet and the modem or router, make sure that's where you'll be using the internet. If you place the router around one corner of the house and you'll be using it in another, you won't get the strong signal strength of the wifi. That’s also why you get strong wifi signal but slow speed.

Solution:

Place your router where it is easily accessible and close to where you will be using the internet. If you can't change the location of your wifi router, you can simply sit closer to it.

Too many devices that consume more data

When connecting your mobile phone to wifi, you usually do not disable the app in the background. In fact, these apps consume your wifi signal and it causes wifi suddenly slow.

Solution:

If your case is due to this reason, it’s quite easy to troubleshoot slow wifi. When you are not using any app you can turn it off. Besides, good practice is to turn off portable wifi when you are not using it.

Turn off background apps
