Seems to have been hardware issues in the end with Dell diagnosis with a repair needed to the motherboard. Currently awaiting delivery of laptop after repair
Hi I use an XPS 15 7590. I have an Intel ax200 Wi-Fi card and had a killer 1650 before. I downloaded and installed drivers for Bluetooth and Wi-Fi. The Bluetooth works fine but Wi-Fi still doesn’t work and can’t be detected on device manager. I already updated BIOS and installed the latest drivers but still nothing. Id appreciate your help.
