WiFi Not Working? 10 Fixes to Try Before Calling Your ISP
Your internet is slow, keeps dropping, or won't connect at all. Before you call your ISP (and wait on hold for 45 minutes), try these troubleshooting steps. Most WiFi problems have simple fixes that don't require a technician.
Quick Fixes (Try These First)
1. Restart Your Router and Modem
The oldest trick in the book — and it works about 60% of the time. Unplug your router (and modem, if separate) from power. Wait 30 full seconds (not 5 — the capacitors need to fully discharge). Plug the modem back in first, wait for all lights to stabilize, then plug in the router. Give it 2-3 minutes to fully boot.
2. Check If It's Your Device or Your Network
Try connecting a different device to WiFi. If your phone works fine but your laptop won't connect, the problem is the laptop. If nothing connects, it's the router or your ISP.
3. Move Closer to the Router
WiFi signal weakens dramatically through walls, floors, and distance. If your signal is strong next to the router but dead in your bedroom, it's a range/coverage problem, not an internet problem. Solutions: move the router to a central location, use a WiFi extender, or upgrade to a mesh system.

4. Run a Speed Test
Go to fast.com (Netflix's speed test — simple and ad-free). Test near the router first, then from where you normally use your computer. If you're getting your full speed near the router but half that in another room, it's a signal strength issue.
5. Check How Many Devices Are Connected
Every device on your network shares the bandwidth. A family of four with phones, tablets, laptops, smart TVs, and gaming consoles could easily have 15-20 devices connected. Log into your router (usually 192.168.1.1 or 192.168.0.1 in your browser) to see all connected devices. Disconnect anything you're not using.
6. Switch WiFi Bands
Most modern routers broadcast two networks: 2.4 GHz (longer range, slower, more interference) and 5 GHz (shorter range, faster, less interference). For devices close to the router, use 5 GHz. For devices far away or through walls, use 2.4 GHz.
Windows-Specific WiFi Fixes
7. Flush DNS Cache
Open Command Prompt as administrator and type: ipconfig /flushdns then press Enter. This clears cached DNS entries that can cause connection issues with specific websites.
8. Reset Network Settings
Settings → Network & Internet → Advanced network settings → Network reset. This reinstalls all network adapters and resets all networking components to default. You'll need to re-enter your WiFi password afterward.
9. Update or Reinstall WiFi Drivers
Device Manager → Network adapters → right-click your WiFi adapter → Update driver. If that doesn't help, try "Uninstall device" (check "Delete the driver software"), restart, and let Windows reinstall fresh drivers.
10. Disable WiFi Sense and Hotspot Sharing
Settings → Network & Internet → Wi-Fi → turn off "Connect to suggested open hotspots" and "Hotspot 2.0 networks." These features can cause your computer to connect to random networks instead of yours.
When It's a Hardware Problem
If you've tried everything above and your WiFi still doesn't work, the issue might be:
- A failing WiFi card — internal WiFi adapters can degrade over time, especially in laptops 5+ years old
- A dying router — routers typically last 3-5 years. If yours is older and acting up, it might be time for a replacement
- Antenna damage — laptop WiFi antennas run through the display hinge. A dropped or sat-on laptop can break them
- Interference — microwaves, baby monitors, cordless phones, and Bluetooth devices all operate on 2.4 GHz and can interfere with WiFi
We can diagnose WiFi hardware issues and replace failing WiFi cards in most laptops and desktops. Our tune-up service also includes network optimization to make sure your software settings aren't slowing things down.
