If none of these solutions work, it's possible that there might be restrictions on the network you're trying to use, especially since you're abroad. Some public networks or hotel WiFi systems may require additional authentication or have limitations on usage.

Does it only happen in one place or everywhere no matter where you are?

First, you can try changing your DNS settings. Go to the Control Panel on your laptop and find the Network and Sharing Center. Look for your Wi-Fi connection and open its properties. There, you'll see an option for Internet Protocol Version 4 (TCP/IPv4). Open its properties and manually set the DNS server addresses to 8.8.8.8 for the preferred server and 8.8.4.4 for the alternate server. Save these settings and try connecting to the internet again.

Another thing you can try is disabling IPv6. Go back to the Network and Sharing Center, find your Wi-Fi connection, and open its properties. Uncheck the option for Internet Protocol Version 6 (TCP/IPv6), save the changes, and restart your laptop.

Clearing your browser's cache might also help. If you use Chrome, open the browser and go to the settings menu (three dots in the top-right corner). Find the Privacy and security section and clear your browsing data, specifically the cached images and files, as well as cookies and other site data. Then, try accessing the internet again.

Temporarily disabling your firewall can sometimes help diagnose if it's the cause of the issue. Go to the Control Panel, then System and Security, and open Windows Defender Firewall settings. Turn off the firewall for both private and public networks and see if that allows you to connect to the internet. Remember to turn the firewall back on afterward for security.

Check if the network you're trying to connect to has any restrictions. Sometimes public or work networks require additional login steps or have limited access. If possible, contact the network administrator to confirm this.

You can also run the Windows Network Troubleshooter. Open the Settings menu, go to Update & Security, and find the Troubleshoot section. Run the troubleshooter for internet connections and follow the instructions it provides.

Make sure your network adapter drivers are up to date. Open Device Manager from the Start menu, find your network adapter, and check for any available driver updates.

Running a full system scan for malware can also help. Use Windows Defender or any other trusted antivirus software to check if there are any malicious programs affecting your network.

You can reset the TCP/IP stack through the Command Prompt. Open the Command Prompt as an administrator and type in a few specific commands: first reset the TCP/IP stack, then release and renew your IP address, and finally flush the DNS cache.

Lastly, try connecting to a different Wi-Fi network. This can help determine if the problem is specific to one network or if it's an issue with your laptop itself.

If none of these steps work, provide more details about your laptop model, operating system, and any specific error messages you see. This information can help pinpoint the issue more precisely.

Hello Marco, thank you so much for your swift answer. Changing the DNS server was a great idea, completely forgot about that, sadly this wasn’t the issue. I tried everything from your list but the error remains the same.

Do you have any other idea of what could be the issue? And please tell me if you need more info

Kind regards

Lukas

Hello Lukas, sorry about your problems. My name is Marco and I will do my best to help you.

Sometimes, the firewall can interfere with internet connectivity. Try disabling it temporarily to see if it resolves the issue:

-Type "Windows Defender Firewall" in the Start menu search

-Click on "Turn Windows Defender Firewall on or off"

-Select "Turn off Windows Defender Firewall" for both private and public networks

2. Try changing your DNS server settings to use public DNS servers like Google's (8.8.8.8 and 8.8.4.4) or Cloudflare's (1.1.1.1 and 1.0.0.1). Here's how:

-Go to Network & Internet settings

-Click on "Change adapter options"

-Right-click on your WiFi connection and select "Properties"

-Select "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties"

-Choose "Use the following DNS server addresses" and enter the public DNS server addresses.

3. Ensure that your browser is not using a proxy server:

-Open Chrome settings

-Go to Advanced > System > Open proxy settings

-Make sure "Automatically detect settings" is on and "Use a proxy server" is off

4. Ensure your laptop's time and date settings are correct, as incorrect settings can cause connectivity issues.
