So my Wi-Fi router and that works well and also on my other devices (cell phone and iPad) the Wi-Fi and internet works completely, only on my laptop (Windows 7) nothing works anymore. I tried it with 4 browsers and tried several times to disconnect and reconnect the Wi-Fi (also tried restarting, etc.) but nothing helped. Does anyone know what I can do?
Does your laptop support Wi-Fi (can you connect to Wi-Fi)?
Do you have a Wi-Fi connection?
Can you, if necessary, call up the router interface from the notebook?
If no, you have a problem with the notebook or the device has been locked in the router.
Do other devices work properly in the Wi-Fi?
If not, the router has a problem.
And the date and time on the notebook are correct. If not, many websites can't be loaded because many websites are now accessed encrypted via https and the encryption / decryption can't work with the wrong date / time setting.
I would first switch to Windows 10 because there's no longer any support for Windows 7. It's still free. The Windows 7 key is also accepted when activating Windows 10.
To do this, first read out the Windows 7 key with this tool https://www.chip.de/...63752.html and write it down.
Then download the Media Creation Tool from the Microsoft website. With it you can create a Windows 10 USB boot stick. For this you need an empty formatted stick.
Then boot the created stick and follow the instructions of the wizard. It offers the possibility to delete everything. One should do that. The installation will restart several times. After completing the installation, the last restart takes place and then the Windows 10 initial setup wizard appears. It offers the possibility to create a Microsoft account. You should do that if you don't have one yet. Then log in to Windows 10 with your Microsoft account. Now go to activation and activate Windows 10 with the Windows 7 key you noted down. The activation will then be saved permanently in your Microsoft account.
The last step is to go to the manufacturer's website for your laptop. Download and install the drivers there.
Do I keep all my data or should I save it on a stick or something?
Everything will be deleted. You should first copy your important data (documents, pictures, photos, music, videos, etc.) to an external hard drive or to your Google Drive.
With this method you then have a clean Windows 10 installation.
Yes, it is connected but still can't access the internet
