Why Is My Internet Slow?

A sluggish internet connection can derail your workday, ruin a streaming session, or make video calls unbearable. Before spending money on a new plan, it's worth understanding why speeds drop and what you can do about it yourself.

1. Restart Your Router (the Right Way)

This sounds obvious, but most people do it wrong. Don't just flip the power switch. Unplug the router and modem completely, wait a full 60 seconds, then plug the modem in first, wait 30 seconds, then plug the router back in. This clears the device's memory and forces it to re-establish a clean connection.

2. Move Your Router to a Central Location

Wi-Fi signals radiate outward in all directions. If your router is in a corner room or tucked inside a cabinet, you're losing significant range. Place it in a central, elevated, open location for the best coverage throughout your home.

3. Switch to the 5 GHz Band

Modern routers broadcast on two frequencies: 2.4 GHz and 5 GHz. The 5 GHz band offers significantly faster speeds but shorter range. If you're close to the router, connecting to the 5 GHz network can instantly improve performance.

4. Reduce Interference from Other Devices

Microwaves, baby monitors, cordless phones, and even neighboring Wi-Fi networks can interfere with your signal. Try changing your router's Wi-Fi channel in its settings. Apps like WiFi Analyzer (Android) or Wireless Diagnostics (Mac) can help you find a less congested channel.

5. Use an Ethernet Cable

For devices that stay in one place — desktops, smart TVs, gaming consoles — a wired Ethernet connection is almost always faster and more stable than Wi-Fi. It eliminates wireless interference entirely.

6. Update Your Router's Firmware

Router manufacturers regularly release firmware updates that fix bugs and improve performance. Log into your router's admin panel (usually at 192.168.1.1 or 192.168.0.1) and check for available updates in the settings menu.

7. Limit Bandwidth-Heavy Devices and Apps

Streaming 4K video, cloud backups, and large downloads can saturate your connection for everyone else on the network. Many routers support Quality of Service (QoS) settings that let you prioritize traffic for specific devices or applications.

8. Check for Unauthorized Users

Someone may be using your Wi-Fi without your knowledge. Log into your router admin panel and review the list of connected devices. If you see anything unfamiliar, change your Wi-Fi password immediately and use WPA3 or WPA2 encryption.

9. Clear Your DNS Cache

An outdated DNS cache can slow down how quickly websites load. On Windows, open Command Prompt and type ipconfig /flushdns. On Mac, open Terminal and run sudo dscacheutil -flushcache. You can also switch to a faster DNS server like Google (8.8.8.8) or Cloudflare (1.1.1.1).

10. Consider a Mesh Network or Wi-Fi Extender

If your home has dead zones that no amount of repositioning fixes, a mesh Wi-Fi system (like those from Eero, Google Nest, or TP-Link Deco) creates multiple access points that work together seamlessly. For smaller spaces, a basic Wi-Fi range extender may be sufficient.

When to Call Your ISP

If you've tried all the above and speeds are still consistently below what your plan promises, it's time to contact your Internet Service Provider. Run a speed test at fast.com or speedtest.net and document the results before calling — it gives you solid data to back up your complaint.
