I recently replaced my wifi/bluetooth adapter in my laptop as it was a poor adapter and had a lot of wifi drop outs. The card I replaced it with is supported by dell, they even provide drivers for it. After a bunch of code 43 (unknown error with device) trouble shooting, I ended up doing a clean instsall just to start fresh to see where I was at.
Upon clean install, that removed the code 43 error, but now I am looking at a code 19 error at bootup. Regardless of the error, the temporary fix is always the same. If I uninstall the driver, scan for hardware changes, the Bluetooth works fine until I reboot. Then the error will come back until I reinstall the driver.
I have uninstalled and deleted the driver and installed a fresh copy of the drivers from Dell's website but that still gives me this same code 19 error. After the clean install, occasionally at boot up it will just disable the Bluetooth driver outright and claim a resource conflict which seems strange to have on a clean install of windows.
I'm stumped on this one. Any ideas on why the issue is always present on bootup? Reinstalling drivers every time I reboot sounds quite annoying.
