So in case anyone is facing the same issue, I contacted support and after a clean Windows 11 install the issue seems to be fixed for good.
This Christmas I got an Inspiron 16 laptop and for the past few weeks I’m having an issue that is driving me insane. Basically, you can work with the laptop with no issue for some hours and then it suddenly loses internet connection. If connected via Wifi, the icon disappears from Windows 11’s lower right menu. If connected via Ethernet (using a Dell DA310z USB-C adapter), it seems to stay connected, but it can’t communicate with anything. Trying to disable and enable the adapter just results in Windows not responding to the command. At that point if I restart the laptop, it will stay in the Rebooting screen for several minutes and then blue screen with the code DRIVER_POWER_STATE_FAILURE. At first, I thought there could a hardware issue with the wireless card, but it makes no sense that it also happens with the ethernet adapter. I have tried running the hardware tests via SupportAssist with no issues found, checking Windows integrity with DISM.exe and reinstalling the wireless drivers with no success. The only thing left that I could think of is restoring Windows 11, but it will be a massive time drain with no warranty of resolving the problem for good. Can anyone help? Thank you.
