Hey there!
My name is Ravi, and I am an independent advisor. I am happy to help you. :)
I understand you're facing an issue with the internet connection.
I suggest you reset your router and change its password.
After that, try updating the WiFi driver.
1). Press Win+X and select the Device Manager.
2). Expand the Network adapters category.
3). Right-click on the WiFi network adapter to select an Update driver option for it.
4). Click on Search automatically for drivers.
Feel free to get in touch again if you have any additional questions.
Cheers,
Ravi
