Refrain from using any VPN

VPNs are great if you need to connect to a specific network. They allow you to choose what type of IP address you want to connect to, whether it’s a public Wi-Fi hotspot, a corporate network, or even a remote office. But there are many reasons why you shouldn’t use a VPN for general internet access. Here are some of the most common ones.

Slow down the internet connection: A VPN slows down your internet connection, making everything else on your device slower too. This includes anything running over Wi-Fi, like email clients, social media apps, web browsers, etc. If you’re downloading files or watching videos, you could end up waiting longer to download those files because of the extra latency caused by a VPN.

Cause problems with other applications: You might think that having a VPN open wouldn’t cause any issues with other apps, but it does. When you’re connecting to a VPN, every app that uses the internet needs to go through the VPN. So if you’re playing video games, you won’t be able to play online without a problem. You can try to avoid this by turning off the VPN once you’ve finished gaming, but that doesn’t always work.
