Wifi Failure (Failed to initialize driver interface)

FreakyCheeseMan · 2014-12-18 19:37:35

Been setting up an old computer that I hadn't touched in a while; bought a new wifi card (Qualcomm Atheros AR9227) yesterday, and got it up and running, put it through a system update, everything worked fine. After rebooting, it would no longer connect, either through wicd or NetworkManager. (Wicd fails after the "Authenticating" step; nm-cli fails after (Getting IP configuration).

I tried to follow the steps from the wiki, but when I do

wpa_supplicant -i wlp5s0 0c /etc/wpa_supplicant/example.conf

I get:

Succesfully initialized wpa_supplicant
wlp5s0: Failed to initialize driver interface

lsmod finds ath9k, ath9k_common and ath9k_hw.

Both wicd and NetworkManager are recognizing the wifi card as well as several wireless networks - they just won't connect to them.

Which drivers does the card support, and have you tried an alternate?

I'm not 100% sure where to look for that information, but the only other options I've found is ath5k and one that's listed as obsolete - I'd have to get the computer online before I could install that, though, and it'll be a while before I get it plugged in directly.

I did manage to get my hands on an external/USB wifi card, which responds in exactly the same way - Failed to initialize driver interface.

The most likely cause of this is having insufficient privileges for the interface driver. Try running as root or with sudo:

sudo wpa_supplicant -i wlp5s0 0c /etc/wpa_supplicant/example.conf

Apologies for the necrobump but this it the top Google search result for the error and might save people some time.

Welcome to the Arch Linux forums, and thank you for the relevant contribution. Relevant contributions do not count as necrobumps

I will, however, use this opportunity to close this old thread.
