Windows PC Keeps Dropping Wi-Fi? Fix It Step by Step

📅 25 July 2026 ⏱ 4 min read 🔧 PC Repair

You're mid-video-call, mid-email, or just browsing — and Windows loses the Wi-Fi connection. You reconnect. Ten minutes later, it drops again. It's one of the most common complaints we hear from residents and expats on the Costa Blanca, and the good news is that in the majority of cases you can fix it yourself without touching a single wire.

This guide walks you through the real causes, in order of how likely they are, so you're not wasting an hour on the wrong fix.

Why Does Windows Keep Dropping Wi-Fi?

There are four main culprits, and they have nothing to do with your internet provider (usually). They are:

Step 1: Turn Off Wi-Fi Power Saving (Do This First)

Windows tries to save energy by shutting down the Wi-Fi adapter when it thinks you're idle. This is the number-one cause of random disconnections — and it takes under two minutes to fix.

  1. Press Windows key + X and click Device Manager.
  2. Expand Network Adapters, right-click your Wi-Fi adapter (it usually has "Wireless" or "Wi-Fi" in the name), and choose Properties.
  3. Click the Power Management tab.
  4. Untick the box that says "Allow the computer to turn off this device to save power."
  5. Click OK and restart.

If the disconnections stop after this, you're done. Seriously — it's that simple for most people.

Step 2: Update Your Network Adapter Driver

A driver is the small piece of software that lets Windows talk to your Wi-Fi hardware. Old or corrupt drivers cause all sorts of connection problems, especially after a Windows update.

  1. In Device Manager, right-click your Wi-Fi adapter again and choose Update Driver.
  2. Select Search automatically for drivers. Windows will check online.
  3. If nothing is found, visit your laptop manufacturer's website (Dell, HP, Lenovo, ASUS, etc.) and download the latest Wi-Fi driver for your exact model.

Not sure which laptop model you have? Press Windows key + R, type msinfo32, press Enter, and look at System Model.

Step 3: Stop Windows Jumping to a Weaker Network

If you have more than one Wi-Fi network saved on your PC — say, your home network, a neighbour's guest network you once joined, or an old router — Windows sometimes switches to a weaker one automatically. The fix is to remove networks you no longer use.

  1. Go to Settings → Network & Internet → Wi-Fi → Manage known networks.
  2. Click on any network you don't use and hit Forget.
  3. Keep only your current home network saved.

Step 4: Reset Your Network Settings in Windows

If you've tried everything above and the problem persists, Windows itself may have a corrupted network configuration. Open Command Prompt as Administrator (search for "cmd", right-click, Run as administrator) and type each of these lines, pressing Enter after each one:

Restart your PC afterwards. This clears out any broken network settings without affecting your files or programmes.

Step 5: Check the Router

If only your Windows PC drops the connection — but phones and tablets stay connected — the issue is almost certainly the PC, not the router. But if all devices drop off, the router is likely overheating or needs a simple restart.

Unplug the router from the mains, wait 30 seconds, plug it back in and give it two minutes to fully restart. If this fixes it temporarily but the problem keeps coming back, the router may be failing — worth a call to your provider (Movistar, Orange, Vodafone, or whichever local ISP you're with).

A Note on Spain-Specific Wi-Fi Issues

In Pinar de Campoverde and along the Costa Blanca, many homes use routers provided by Spanish ISPs that sit in a cabinet or hallway far from the living area. If your PC is at the far end of the house, a weak signal can look exactly like a driver or power problem. Check your signal strength — if it's below two bars, the solution may simply be a Wi-Fi range extender or a powerline adapter, not a software fix.

If you've worked through all five steps and you're still dropping out, it may be time to bring the laptop in. Sometimes the Wi-Fi card itself is failing — we see this fairly often with laptops that are three to five years old. It's usually a straightforward repair. Have a look at our post on 5 warning signs your laptop needs a repair to see if there's anything else going on.

Summary

Most Windows Wi-Fi drop-outs on the Costa Blanca come down to one of four things: power management, an old driver, Windows jumping networks, or a dodgy router. Work through the steps above in order and you'll almost certainly find the fix. No need to panic, and no need to call your ISP for 45 minutes — at least not yet.

FAQ

Why does my Windows PC keep disconnecting from Wi-Fi but my phone stays connected?

This almost always points to the PC itself, not the router. The most likely causes are Windows power management shutting down the Wi-Fi adapter, or an outdated network driver. Follow Steps 1 and 2 in this guide first.

Will resetting network settings delete my files or passwords?

No. The netsh and ipconfig commands only reset network configuration — they do not touch your personal files, documents, or saved browser passwords.

My Wi-Fi drops every few hours exactly. What does that mean?

Intermittent drops on a regular timer are a classic sign of Windows power management cutting the adapter. Go straight to Step 1 and disable the power-saving option for your Wi-Fi adapter.

Can a Spanish ISP router cause Wi-Fi problems on Windows?

Yes, especially older Movistar or Orange-supplied routers. If all devices on the network drop at the same time, restart the router and check its ventilation — Spanish summers mean routers in enclosed cabinets overheat easily. If it keeps happening, report it to your ISP.
