Hello, I am new here. I have a problem with my newly acquired dell xps 15 9570. I just got this laptop 3 days ago and I am already having problem connecting to the wifi. While the laptop is plugged in to electricity, it works just fine. But once I disconnect it to use just the battery, the wifi disconnects and wont reconnect until I plug it in and then restart it I have tried everything I saw online about uninstalling and installing the killer wifi, but nothing is working. Please I need help to resolve this. Thank you
