No more internet, what to do on all other devices?

I haven't had internet for days. On my laptop it shows what I sent as a picture.

Have tried everything but nothing brings anything.

Maybe you have switched off your Wi-Fi?

How turned off? Airplane mode is not on

Does the router no longer receive anything? Is a red LED on?

Router restarted?

Then until you are disconnected from the internet. I'm assuming you've paid your bills, so it can be technical. Check the phone cord to see if you find any damage anywhere. It doesn't have to be the house management either, maybe something will be done somewhere on the

…

I have already activated or deactivated network adapters

No, all LEDs light up green. Other devices just don't work with my laptop.

I did not restart the router because all devices are working

Oh sorry I thought no device is working. Then you have to reinstall the WLAN driver. Isn't there such a diagnostic function? Can you click Troubleshoot?

When I click on problem treatment my Ethernet cable is similar to a telephone cable but I don't use Ethernet.

I also reinstalled the driver for the Wi-Fi… Nothing

So only Wi-Fi ok.

Did you google with your model name?

I can't find my model name. Neither in the battery nor on the underbody.

I have now switched off my antivirus protection for firewall and network protection and now it works again after the restart

Hmm… I know that an antivirus program likes to stunk. Especially where there's none. But it shouldn't turn off the Wi-Fi. But who knows what got in the way… 🤓

Did you turn on DHCP for IP and DNS? Is the LAN cable plugged in or are you on the go via WLAN?

What exactly did you change "a few days ago"?

Have tried everything but nothing brings anything.

According to this sentence, the only logical answer would be: scrap your laptop, buy a new device. What exactly is "everything"?! It is inefficient to try to guess that.

I'm on the go via Wi-Fi. Like today it has been going for almost an hour, for example, but I download the laptop and back up it is gone.

Yes, I'm already considering selling this laptop and getting me a new one.

What does "I download the laptop and upload it back up" mean? The battery or is it about downloading a file? With some devices, the network no longer comes on after sleep mode. Then you can set the energy options accordingly in the device manager.

You still haven't explained enough details to make the problem clear.

I have solved it now I think. Since yesterday my Wi-Fi has been working again. I looked in the settings for VPN and it was switched on somehow. I switched it off, booted up the laptop again and then it worked again.
