I bought two dell desktop machines and… never again. The Wi-Fi cards are the size of thumbnails and were very intermittent. I needed them replaced but couldn’t make a support call for two machines. Had to file two separate support calls. And support techs made me run diagnostics each time, and they had different responses to the same condition. They kept reading off a script and.. well, I was on the brink of insanity. Eventually I bought new PCI Wi-Fi cards and installed them myself. So these machines now don’t have Bluetooth. F Dell.
