b43 AP does not work

Hello,

[14e4:4312] (rev 02)

AP worked on F21. On F22 kernels 4.0.0 and 4.0.1 it does not.

A resource busy error from nl80211 usually means that NetworkManager is 
controlling the interface. Are you using NM? If so, have you tried setting up an 
AP using the "access point" mode of the NM applet. That is a lot easier than 
using hostapd, and has the additional advantage of being able to use wireless 
cards for both the WAN and LAN sides of the AP.

IIRC I used "access point" mode of the NM applet and it worked, but now I
cannot find such option (at least in MATE). Is it somehow possible to still
use hostapd manually?

If you want to use hostapd on the card and the system is running
NetworkManager, you can tell NM to ignore the device through the
"unmanaged-devices" option in NetworkManager.conf.  manpages have more
details.

But I don't want NM to ignore the device - I use the wifi card with NM
as a client. But sometimes I'd like to use hostapd directly (as NM
does not allow me to configure AP parameters - channel, wpa number,
AP name and password). It was possible before, but not any more.

That is an applet problem. I use openSUSE 13.2 with a KDE desktop, and the 
Connection Manager lets me specify everything in your list but perhaps the WPA 
level, but why would you want to use anything less secure than WPA2?

You need to complain to your distro if they have a regression in the NM applet.

It's Gnome, they don't let users to configure :( But thanks, next time I
will know that KDE applet is better.
Does anyone know why it was possible before? Is it NM or hostapd regression?

NM actually does allow you to do that by editing the hotspot connection
files directly.  The various UIs (nm-applet, GNOME Shell, etc) may or
may not expose specific knobs like these.  We intend to add AP mode
support to nm-connection-editor, but there are some complications around
valid options in AP mode that need to be addressed in the editor UI
first.

If you take a look into /etc/NetworkManager/system-connections/ you
should see the config file, where you can edit stuff like 'channel',
'ssid', 'band', 'pairwise', 'group', 'proto', etc, stuff that's familiar
to wpa_supplicant config too.  See 'man nm-settings' for more details on
all these key/value pairs.

I edited /etc/NetworkManager/system-connections/Hotspot, ran systemctl
restart NetworkManager and ssid and password were changed. Then I added
channel=10 to the file, restarted NM, but when I enable hotspot in Gnome,
ssid is localhost.localdomain and password is random again. I was not able
to have my edited ssid and password values back.

You don't actually need to restart NM, you can simply run "nmcli con
reload" to get NM to notice the changes.  I don't recall how GNOME Shell
handles the Hotspot button in its UI, but you should be able to test
independently of GNOME Shell by doing:

nmcli con up <name of hotspot connection>

I did
nmcli con reload
nmcli con up Hotspot

but it still used localhost.localdomain as ssid, although I have
ssid=something in /etc/NetworkManager/system-connections/Hotspot

If you run "nmcli con", is there more than one connection called
"Hotspot"?  If not, then run "nmcli con Hotspot" and lets see what it
prints out.

Yes, there are 2 Hotspots. After I deleted one with nm-connection-editor
the ssid is OK.
