The Basics: Understanding VPNs and WiFi
Before we delve into the reasons behind WiFi disconnections, it’s essential to understand how VPNs and WiFi networks function together.
What Is a VPN?
A Virtual Private Network (VPN) encrypts your internet traffic and routes it through a server before it reaches its destination. This process serves multiple purposes:
- **Increased Privacy**: By masking your IP address, a VPN helps protect your online identity from ISPs and potential intruders.
- **Access to Restricted Content**: VPNs allow users to bypass geographical restrictions on websites and streaming services by connecting to a server in another location.
How WiFi Works
WiFi is a technology that allows devices to connect to the internet wirelessly. It operates using radio waves and involves several components, including:
- **Router**: The device that sends and receives information from the internet.
- **Modem**: A device that connects your home network to your Internet Service Provider (ISP).
When a VPN is enabled, it alters the way your device communicates with the router and the internet, which can sometimes lead to connectivity issues.
Common Reasons for WiFi Disconnection When Using a VPN
Let’s discuss the primary reasons why your WiFi may disconnect when a VPN is active:
