I have a Dell XPS 13 Kaby Lake, running Ubuntu 16.10.
The wireless card in this device is "Killer 1535 802.11ac 2×2 WiFi and Bluetooth 4.1".
Lately, I'm having increasingly severe problems connecting to a network, to the point where I can currently not access the internet at all. I've tried the solution here Getting Killer Wireless-AC 1535 working for installing Ubuntu 16.04, but it's not working for my machine. I used the latest version available at the time of writing (1.162).
I'm getting 2 warnings (
possible missing firmware /lib/firmware/i915/... for module i915) on running
modprobe. After rebooting,
dmesg lines containing

Notice the firmware messages at 41.280.
What could I do? I'm willing to do a downgrade to 16.04 if it would help.
Some other observations:
- I AM connected to the networks that I try to connect to, it seems, and the device is assigned an IPv4 address.
- Entering an url in firefox is not loading anything, however. Also
pinging won't return anything.
- Even though I was able to access the internet when I first installed 16.10, I currently cannot access any sites even when using a clean live USB to "try out Ubuntu".
Here is a screenshot showing that a network is connected, but nothing is coming through ping:
Any suggestions? Many thanks!
