I can no longer connect my laptop to the Wi-Fi. Although four bars are displayed, he always writes "no internet" and does not connect. I have no problems on my cell phone and on another PC. The laptop is brand new, but has been connected to the internet before.
Why is that and what can I do?
Possibly install drivers.
Can have different causes on a PC / laptop.
Please go to the start menu and type in "Network Connections", in the new window all your network devices like LAN, WLAN or WWAN (for cellular) will be displayed.
Double-click on the WLAN adapter and then go to Details.
What is there then with DHCP activated and with IPv4 address?
