Slow Internet — Causes and Solutions

Slow internet can ruin your productivity. Here are 8 ways to fix it:

1. Test Your Real Speed

First, measure your current speed:

Visit speedtest.net or fast.com

Compare with your plan

2. Change DNS

Slow DNS causes delays when opening sites:

Settings → Network & Internet → Adapter properties

Click Edit next to DNS

Use Google DNS: 8.8.8.8 and 8.8.4.4

Or Cloudflare: 1.1.1.1 and 1.0.0.1

3. Restart Router and Adapter

Turn off the router for 30 seconds and turn it back on

On PC: Settings → Network → Disable and re-enable the adapter

4. Flush DNS Cache

Corrupted DNS cache causes problems:

Open Command Prompt as Admin

Run: ipconfig /flushdns

Run: netsh winsock reset

Restart PC

5. Close Bandwidth-Hungry Programs

Open Task Manager (Ctrl+Shift+Esc)

Network tab — see which programs consume the most

Close unnecessary ones

6. Disable Background Updates

Windows Update can consume all bandwidth:

Settings → Windows Update → Advanced options

Limit download bandwidth

7. Update Network Adapter Driver

Device Manager → Network adapters

Update your Wi-Fi or Ethernet driver

8. Use Cable Instead of Wi-Fi

If possible, connect via Ethernet cable — it's always faster and more stable than Wi-Fi.

Frequently Asked Questions

Internet slow only on my PC, other devices are fine?

The problem is your PC's network adapter or DNS. Restart the adapter, change DNS and update the driver. Resolve AI can do this automatically.

Does changing DNS really improve speed?

DNS doesn't affect download speed, but affects how quickly sites open. Google DNS (8.8.8.8) or Cloudflare (1.1.1.1) are generally faster than ISP DNS.
