Killer 1525 Wireless Card can't connect

[Arcfire]

Hello, I recently installed Kali on a live USB using these instructions for Windows. Kali works great, but it won't connect to the Internet wirelessly. This is a clean install; I wiped the USB and started over after bumbling around on this issue for a while.

I have a Qualcomm Atheros Killer 1525 wireless adapter on an Alienware 15 I just purchased this fall. I can connect just fine on Windows, but am forced to use Ethernet for Kali if I want to connect to the Internet.

Here are some outputs for commands I have been told could be useful:

I'm a bit of a newbie to this, but I'm willing to learn. Any help would be greatly appreciated.

I just had this same issue with my Alienware 15 R2. Try this:

modprobe alx
echo 1969 e0a1 > sys/bus/pci/drivers/alx/new_id

This will restore your ethernet, so plug it in and update your system.

apt-get update
apt-get dist-upgrade

After dist-upgrade completes, reboot and you should now have Wi-Fi connectivity. If you notice that your fonts are displaying as boxes you can fix them with:

apt-get install --reinstall fonts-cantarell

Hope this gets you back up and running!
