I have no wireless connections. We recently switched our internet service provider and I cannot see the new wireless router/modem. This is the output from the wireless info script:

I would really appreciate it if someone would tell me how to fix this.

ls | grep back; dkms status

  • Please edit to include ls | grep back; dkms status thanks

  • You should upgrade your kernel. Before trying anything else, run 'sudo apt-get install linux-generic-lts-wily'.

You don't need backports or the backath10k dkms I made for the AR9485 card to work. So we will remove them

cd backports-20150903
sudo make uninstall
sudo dkms remove backath10k/2.0 --all

Reboot

After reboot your lspci -nnk | grep -iA2 net should show
