Så lad os dykke ind!

Hurtige løsninger

Start with these steps first:

• Genstart Wi-Fi-routeren: Power cycle your router by turning it off for 10 seconds, then turning it back on to refresh the connection.
• Ensure your Wi-Fi is turned on: Double-check that your router is plugged into power and working.
• Genstart din pc: Tap the Start menu > Power > Restart.
• Prøv at bruge et Ethernet-kabel: Connect your computer directly to the router with an Ethernet cable to bypass Wi-Fi issues and restore internet access.
• Turn on the Wi-Fi button on your computer: Some computers have a physical button or switch that you have to turn on.

Enable Wi-Fi Service

First, make sure that you haven’t turned off the Wi-Fi feature by mistake. Follow the steps below:

1. Tryk Windows Nøgle + I at åbne Indstillinger. 
2. Tryk på Netværk og internet > Avancerede netværksindstillinger.

3. Make sure the Wi-Fi button reads “Disable.” If not, tap “Enable.”

Turn on the WLAN AutoConfig Service

WLAN AutoConfig is a crucial Windows service that manages your computer’s wireless networks. If this service is turned off or not functioning properly, do this:

1. Presse Windows + R for at åbne dialogboksen Kør. Type services.msc og hit Indtast.

2. Rul ned til WLAN AutoConfig in the Services window, double-click it, and set the Starttype til Automatisk Ur.

3. If the service isn’t running, right-click on it and tap Starten.

4. Klik Ansøg og så OK for at gemme dine indstillinger.

Opdater netværksdriver

An outdated or corrupted network driver is one of the most common reasons why your computer might not be able to find Wi-Fi networks. Here’s how to opdater det:

1. Højreklik på Starten menuen og vælg Enhedshåndtering.

2. Udvid Netværkskort section. Right-click on your Wi-Fi adapter and select Opdater driver.

3. Vælg Søg automatisk efter drivere. Windows will look for the latest ones online.

Alternativt kan du brug PC HelpSoft Driver Updater. This tool automatically scans and updates your drivers, streamlining the process and saving you time.

After updating, restart your computer and check if Wi-Fi networks are visible.

Run the Internet Connections Troubleshooter

Windows has a built-in troubleshooter that can automatically detect and resolve many common network issues. Follow the steps below:

1. Press the Windows Key + I to open Indstillinger. 
2. Scroll and click Fejlfinding.

3. Type Other trouble-shooters.

4. Tryk på Kør ved siden af Netværk og internet button. Follow the prompts to let Windows diagnose and fix potential problems with your connection.

Reset TCP/IP Stack

Sometimes, network settings can become corrupted, preventing your computer from properly detecting Wi-Fi networks. Resetting the TCP/IP stack often resolves these issues. Here’s how:

1. Tryk Windows-tast + X, tryk derefter på Terminal (admin).

2. Type netsh int ip reset og hit Indtast.

After the command completes, restart your computer to reset the TCP/IP stack.

Nulstil netværksindstillinger

If you’re still having trouble connecting to Wi-Fi, try restoring all networking components to their default settings. Follow the steps below:

1. Tryk Windows Nøgle + I at åbne Indstillinger.
2. Gå til Netværk og internet on the left sidebar, scroll down, and click on Avancerede netværksindstillinger.

3. Under Flere indstillinger, Vælg Netværks nulstilling.

4. Klik Nulstil nu og bekræft dit valg.

After the reset, confirm if you can find Wi-Fi.

Check Wi-Fi Adapter Power Settings

Sometimes, your Wi-Fi adapter may be set to power-saving mode, which can cause it to stop scanning for available networks. Disabling power-saving features might help:

1. Åbne Enhedshåndtering again (right-click Start > Enhedshåndtering).
2. Under Netværkskort, right-click your Wi-Fi adapter and select Ejendomme.

3. Tryk på ikonet Power Management fane. Fjern markeringen af "Tillad computeren at slukke denne enhed for at spare strøm" boks og klik OK for at gemme ændringer.

This ensures your Wi-Fi adapter is always active and can detect available networks.

Udfør en systemgendannelse

If none of the above solutions work and the issue started recently, try restoring your system to a previous point in time when the Wi-Fi connection was working. It’s helpful if a recent update or software installation caused the problem. Follow the steps below:

1. Type "Opret et gendannelsespunkt," on the search bar and tap Åbne.

2. Klik på Systemgendannelse.

3. Vælg et gendannelsespunkt og tryk på Næste.

4. Klik Finish for at starte gendannelsesprocessen.

After restoring your system, check if your network is visible and working again.

So, now you know what to do if your computer can’t find Wi-Fi. Start with the simple fixes before moving on to more advanced solutions. These steps should help you get your connection back up and running.
