WiFi Connection Problems

What this error means

WiFi issues can range from slow speeds to complete disconnections. Your computer might show connected but have no internet, drop connection randomly, or fail to find networks at all.

These problems can be caused by your computer, router, ISP, or interference from other devices.

Common causes

1Router issues or outdated firmware
2Distance from router or physical obstructions
3Interference from other devices
4Outdated network drivers
5IP address conflicts
6DNS server problems
7ISP outages or throttling

How to fix it

Step 1: The Classic Restart

Turn off your computer's WiFi
Unplug your router for 30 seconds
Plug router back in and wait for all lights to stabilize
Turn WiFi back on and reconnect

Step 2: Forget and Reconnect to Network

Windows: Settings → Network & Internet → WiFi → Manage known networks → Select network → Forget
Mac: System Settings → WiFi → Details (next to network) → Forget This Network

Then reconnect by entering the password again.

Step 3: Update Network Drivers

Windows: Device Manager → Network adapters → Right-click your WiFi adapter → Update driver
Mac: Usually handled by macOS updates

Step 4: Reset Network Settings

Windows: Settings → Network & Internet → Advanced network settings → Network reset
Mac: Delete files in /Library/Preferences/SystemConfiguration/ starting with "com.apple.network" (advanced)

Step 5: Change DNS Servers

Try using Google DNS (8.8.8.8, 8.8.4.4) or Cloudflare DNS (1.1.1.1, 1.0.0.1) for potentially faster, more reliable connections.

Step 6: Check for Interference

Move closer to your router
Switch from 2.4GHz to 5GHz band (faster but shorter range)
Move router away from microwaves, baby monitors, and other electronics

When to seek help

Contact your ISP or consider professional help if:

All devices have the same WiFi issues (likely router/ISP problem)
Only your computer has issues on multiple networks (likely hardware problem)
Speed tests consistently show much slower than your plan
Connection drops happen at specific times (possible ISP issue or interference)
