I am having trouble installing the correct drivers for the "Feb Smart Wireless Dual Band N600." The card worked instantly on Windows 10, but seems it can't find a driver on Ubuntu 18.04 LTS. The sale page says that it is compatible with Linux through Ath9k, which I believe should be included by default in the kernel. However, when I run

sudo lshw -C network

I get the following output:

  *-network

I believe that "UNCLAIMED" means that there is no driver for the device. How should I fix this?

lspci -nnk | grep -e 0200 -e 0280 -A3

gives

  • Please see: pci-ids.ucw.cz/read/PC/168c/abcd Is your card seated firmly in its PCI slot? Is the BIOS reset to defaults? Is the BIOS fully updated?

  • It is firmly seated. I'm not sure how to reset the bios or update it (it hasn't been updated since I got the motherboard about a year ago) would that require me flashing it? It would seem odd for it to be a bios issue considering it works ok with Windows 10 on the same computer.

  • Yes, a BIOS update requires flashing it. Windows is not Linux and vice versa.

Go to

/etc/modprobe.d

Look for a file named something like

blacklist-ath_pci.conf

do

sudo gvim blacklist-ath-pci.conf

look for something like

blacklist Ath9k

If the above is present, comment out that line, save the file, reboot and the driver should be active.
