I managed to resolve this by getting internet to my dell laptio via bluetooth.  Opened  Dell Update,  then proceeded to download and install the BIOS update that was available.  once rebooted the driver was working again. Hope this can help you.
This Monday the wifi, along with the bluetooth, on my laptop stopped working. Each time I attempt to disable and re-enable the driver it get the status message: "Windows has stopped this device because it has reported problems. (Code 43)". I've ensured all drivers are updated including updating the BIOS, and am on latest version of windows. I found a number of errors in the Event Viewer (attached below) which appear to indicate a configuration issue with the hardware, i.e. "Killer(R) Wi-Fi 6 AX1650s 160MHz Wireless Network Adapter (201D2W) : A required parameter is missing from the registry." however when testing the laptop on a Ubuntu Live CD I found the Wifi adapter was not recognised at all. I even did a factory reset after running out of options. This has me fearing its a hardware issue. I've seen reports similar to this issue on this forum however the solutions provided there (mainly updating drivers & changing Advanced Properties in driver) did not work. If it does turn out to be a hardware issue are these wireless network adapters easily replaced? My laptop is 2 years old now so the warranty has expired. Hope one of you's can give me some helpful advice. Thanks
