Common Causes of Slower Internet Speeds
Several factors can contribute to reduced internet speed, including:
- ISP Throttling: Your ISP may deliberately slow down your connection during high usage or when streaming.
- Network Congestion: Shared networks (like public Wi-Fi) often experience heavy traffic.
- Outdated Equipment: Old routers or modems can bottleneck your speeds.
- Long Distance to Servers: The farther the server, the slower the response time.
- Free or Overloaded VPNs: Cheap/free VPNs often limit speed due to crowded servers or bandwidth caps.
Can a VPN Fix Slower Speeds?
Yes — in many cases, a premium VPN can actually improve your speed. Here’s how:
- Bypassing ISP Throttling: ISPs often throttle based on activity (like HBO Max). A VPN hides your traffic, preventing throttling.
- Optimized Routing: Some VPNs use smart routing to send your data through faster, less congested paths.
- Server Choice: Good VPNs offer servers near your location, reducing latency.
- Note: A low-quality VPN can make speeds worse. Always choose a trusted provider.

You’re using a VPN on very old devices
Your base internet speed is already low
Still, a high-quality VPN will minimize this impact — and in many cases, bypass ISP throttling for a net performance boost.

FAQ – Slower Speeds
Does a VPN always slow down your internet?
No. A good VPN may even speed up your connection by bypassing ISP throttling.

Public Wi-Fi networks are often congested and insecure. A VPN encrypts your data but may reduce speed slightly if the network is already slow.
Can a VPN help with Netflix buffering?
Yes. Surfshark, NordVPN, and ExpressVPN all reduce buffering on Netflix and other streaming platforms by preventing throttling.
What’s the fastest VPN protocol?
Lightway (ExpressVPN) and NordLynx (NordVPN) are among the fastest protocols available in 2025.
