Hi
after I restarted my laptop (apps are deleted, personal data remain) my internet went really bad after a few days or weeks. The browser has become a bit slower and sometimes the error no internet comes (this dino) and I get disconnected from my Wi-Fi
has the performance also got worse?
ps: all other devices at home work well with the wlan
I would restart router.
Restart the PC.
If it still doesn't work properly, uninstall the wireless driver and reinstall it.
And also delete the WLAN profile (using the "Do not save" button) and reconnect to your WLAN.
