Operation not supported on arm #5

I'm getting the following errors trying to use wpa_supplicant in wext mode:

# journalctl -fu wpa_supplicant@wlan0
-- Logs begin at Sat 2016-05-21 22:31:33 UTC. --
May 21 22:34:48 qr6 wpa_supplicant[539]: wlan0: CTRL-EVENT-SCAN-FAILED ret=-1 retry=1
May 21 22:34:49 qr6 wpa_supplicant[539]: ioctl[SIOCSIWSCAN]: Operation not supported

Same in all the other driver modes.

iwconfig returns:

wlan0     no wireless extensions.

iw list returns:

# iw list
#

... nothing

And lsmod:

Any ideas?

Hi,

Is the driver working anyway ? Or this is only an annoying bug ?

Please check also the wireless-ext.branch. This is my cleaning branch for cherry pick into rtlwifi

master is currently not updated, to maintain it pullable.

paralin commented 8 years ago

Doesn't seem to work. I'd love to try wireless-ext.

Will do today.

paralin commented 8 years ago

Tried wireless-ext on the latest kernel version and I'm getting the same thing.

iw list is empty, and iwconfig prints "no wireless extensions"

Hi,

I made some tests on laptop running Sabayon Linux/Limbo aka testing with systemd v226 HW:D-LINK DWA 171 works like a charm

Other HW some Zyxel NSA 325 with Marvell Kirkwood Kernel v4.6.2 Minimal setup only ~8 MIB initramfs with basic tools. Also OK, I do some of my speed / scripting tests here ...

This error is part of wireless-ext in /core of the driver and this directory doesn't exist in the rtlwifi branch, because it's not needed.any more.

Only /rtl8821au will survive and currently this can't be pushed -> broken as hell

Well... You haven't suggested how to fix this and I can no longer get your driver working at all so im probably going to just switch to some other fork...

@paralin Perhaps worth checking out upstream's rtl8xxx generic driver? It might substitute Uli Kroll's work in the future:

http://lxr.free-electrons.com/source/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.c

  * This driver was written as a replacement for the vendor provided
  * rtl8723au driver. As the Realtek 8xxx chips are very similar in
  * their programming interface, I have started adding support for
  * additional 8xxx chips like the 8192cu, 8188cus, etc.

git grep USB_VENDOR_ID_REALTEK drivers/net/wireless/realtek/ does not print any of the 802.11ac WIFI NICs. Not even the ID's for the demoboards, which some OEMs are using for their product. Sorry for that.

On the other hand I have queued one or more patches for upstream, related to usb probe. Without this my rtlwifi branch will not compile.
