Hi Simon,
I may be wrong on this (I am responding on my phone as I am away from
my PC), but if I remember correctly, the backend that you use depends
upon the driver that your card uses. Some need the backend specified
and some don't. I have never personally had a card that requires this,
but I know that such cards exist.
Hmm, yes I suppose that's possible. The wpa_supplicant documentation
says that it "uses the first backend that successfully initialises the
card", but maybe the "autodetect" step with the wpa_supp wext backend
goes wrong even when that backend _does_ actually work with the linux
wireless extensions for the driver behind the network interface. Or
maybe one of the other backends reports success but then fails to work.
I'll see if "-dd" (enable debug output) gives any more info.
I'm running this on a laptop with onboard Intel wireless, using the
iwlwifi kernel module. So it's not anything very exotic but is
reasonably new. lspci reports:
03:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)
Or maybe it could be a kernel version issue? However I'm using the
normal LFS-7.7 kernel (3.19) so I would think others would notice.
Thanks & Regards,
Simon
