problem with realtek usb wi-fi

[maggie2]

I'm trying to get my usb wi-fi called "Vilros 150 Mbps wireless 802.11b/g/n nano USB adapter" to work.

$this->bbcode_second_pass_code('', '# lsusb
Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter')

I get this error:
$this->bbcode_second_pass_code('', '# wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/example.conf
Successfully initialized wpa_supplicant
nl80211: Driver does not support authentication/association or connect commands
wlan0: Failed to initialize driver interface
')

The hardware is good because I can plug it into my Arch x86_64 box and it works just fine.

The 8192cu module is loaded on my Pi.

The hardware is seen by ip:

I have tried using the included 8192cu module and the alternative version in dkms-8192cu without any success. Any advice?

[maggie2]

It seems that the hardware works perfectly fine with the standard module provided by linux-raspberrypi if I use netctl and not wpa_supplicant
$this->bbcode_second_pass_code('', 'sudo wifi-menu -o
Scanning for networks... ioctl[SIOCSIWAP]: Operation not permitted
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
done
')

I can then connect to whatever I want from the menu but I want to use systemd native network management for my wired and wireless and I think it only interacts with wpa_supplicant so the question is why doesn't wpa_supplicant work with my RPi?

Seems as though wpa_supplicant is on v2.4 now but the repos have v2.3. I know you said that the hardware works on x86_64 but maybe there is a fix for this in the new release? You'll have to read through the changelog or just build it and see if it helps.

I compiled it but there is not change using the new version
