So I recently got a dell xps 15 with the idea of using it as a linux machine. I assumed it would work pretty smoothly given the xps's reputation with linux, but I'm having quite the amount of trouble getting the wifi working.
So when I first tried Ubuntu 16.04 and 17.10 the wifi actually worked, sort of at least. I could connect to my the guest network at my university, but not the secure network. Then, the wifi just stopped working all together a day later.
The confusing thing to me is that there seems to be a lot of other people who got Ubuntu working straight out of the gate. This person didn't seem to have any issues with the wifi. I tried updating the bios because I saw somewhere that that might help, but that didn't seem to do anything.
The chip is a Qualcomm Atheros Killer 1535 802.11ac to be specific. Any help is appreciated. Thanks.
EDIT: I should clarify, the wifi networks show up. So the card is being used in someway. But I can't connect to any network.
