Laptop lost the wireless function?

I have a Lenovo laptop and we recently got a new router. Whenever I log in with the password from the router, it works, but no network connection is possible. With the Ethernet cable, everything just doesn't work with the one without a cable. I think the function with the wireless Wi-Fi so wireless Wi-Fi was deleted, probably by me… 😩😭 Because before that my laptop could be connected without a cable. Does anyone know the problem by accident or maybe even an app with which you can fix it?

I look forward to your help!

Call the device manager and look for components with a yellow exclamation mark.

With the Ethernet cable, everything just doesn't work with the one without a cable.

Lan (cable) is also the better option because it is more stable, faster and better. Above all, fewer disconnects or transmission problems.

Simply switch off Wi-Fi and use Lan, then you have peace in the long run.

I only use Lan at home and no longer have Wi-Fi and have been doing so for at least 10 years.

Hello first of all thanks for your new answer, I just checked but there are no components with a yellow exclamation mark…

Thanks for your answer, I was just wondering why the connection is not established…

Although I did find something here, there's a warning in the Windows Protocol Applications folder with a black exclamation mark in a yellow box

👍 what is the full text of the ⚠️? Possibly double click> Properties?
