xps 15 9510 connecting to wifi but not connecting to the internet

Hi everyone,

My XPS 15 9510 always has bad wifi connectivity and recently when i changed my internet provider all devices are working fine apart from my laptop.

The laptop is connecting to the wifi but the internet completely stops working. My system is running windows 11 pro and i have done all of the necessary updates but is still not working.

I have read that if i reinstall the killer intelligence app it would help the issue (still having the same issue) and if i try to download the older version of killer but when i downloaded the older version it said killer driver can not be found on my laptop.

Any help?

Thanks in advance
