Setting up an AP @ 5 GHz 802.11a - hostapd refuses [Could not select hw_mode and channel. (-1)]

Setting up an AP @ 5 GHz 802.11a - hostapd refuses [Could not select hw_mode and channel. (-1)]

[Alfonso Fiore]

Hi,

I have an embedded system (ALIX) with an Atheros AR5414 chipset (802.11 a/b/g)

I realized I have a wireless pollution problem at 2.4 GHz, so I
thought to setup an 802.11a AP (5 GHz).

hostapd tells me I have only 2.4 GHz channels available. Why?
Is there a chance to use the 5 Ghz channels? As I realize it's a
regulatory issue, I live in France.

I attached output of
- /usr/sbin/hostapd -dd  /etc/hostapd/hostapd.wlan0.conf
- iw list
- cat /etc/hostapd/hostapd.wlan0.conf

thank you,
alfonso

Re: Setting up an AP @ 5 GHz 802.11a - hostapd refuses [Could not select hw_mode and channel. (-1)]

[Alfonso Fiore]

Ok I studied some more.

I found an howto http://forum.aircrack-ng.org/index.php?topic=7826.0
to edit db.txt and create a custom regulatory.bin (including the
openWrt patch to drivers/net/wireless/ath/regd.c).

I also found out about ath_info
http://madwifi-project.org/wiki/UserDocs/AthInfo and I rewrote my
regdomain:
./ath_info -v -g 4:0 -w 0xeffd0000 regdomain 0x68

I can tell these things worked since I can now fully access the 2.4
GHz channels (before I couldn't use 12 and 13):
Wiphy phy0

*** But why I still can't access any channel at 5 GHz? *** and what's
the meaning of (disabled)? Is this due to a hardware limitation?
In the 2.4 band, I managed to switch channel 12 and 13 from (passive
scanning) to available and channel 14 from (passive scanning) to
(disabled). Why?

This is the situation at 5 Ghz:

That may be dangerous.  Not all cards work with ath_info, and some can
be broken by it permanently.  It's much safer to adjust
ath_regd_sanitize() in drivers/net/wireless/ath/regd.c.

That way, you can play with different regdomain settings.

I believe it's a regdomain limitation.

I think it means it should be possible to use the band as long as DFS
is implemented, but it's not (in ath5k).

Try other regdomains, I think some should enable 5GHz unconditionally,
but please keep in mind that you may be breaking regulations.

Hi Pavel and thank you,

I tried for days and finally I realized that when I do "make install"
still my box does not run my new code.
The only way I managed to use 5 GHz channels was setting my regdomain
to 0x00 with ath_info.

I really would like to know why my debian based box does not run my
modified compat-wireless code after "make install".

Any idea?

Thank you,
alfonso

I always have to issue a "depmod -a" after make install. You can check
if the new modules are used afterwards with
"modinfo modname[without .ko]" and check the given path. It should
contain "updates".
Sometimes, it is necessary for me to insert a "depmod -a" even before
make install, because of missing files, which are needed by the
installation and which are created by depmod -a.


Kind regards,
Andreas

Hi Andreas,

Any idea?

Sorry for being late. I worked on my machine and wasn't able to read any
mails.


I do have a config file for depmod in /etc/depmod.d called
00-system.conf, which has the following entries:

--------------------------------------------------------------------
#
# /etc/depmod.conf - configuration file for the depmod(8) command,
# for its format see depmod.conf(5).
#
# Please don't edit this file, place your settings into the /etc/depmod.d
# directory.


# search order:
# 1 updates/ (KMPs)
# 2 extra/ (KMPs or manually compiled modules)
# 3 weak-updates/ (KMPs built for older kernels)
# 4 everything else
search updates extra weak-updates built-in

# do not generate modules.*map files
make_map_files no
----------------------------------------------------------------------

Version of my inittools is: module-init-tools-3.12-6.1.x86_64. I don't
have a depmod.conf file.

After creating / changing this file, issue depmod -a again!



Hope that helps!

Regards,
Andreas

Hi Andreas,

I do not have a /etc/depmod.d folder. I imagine it is something about
my embedded distribution (voyage 0.8.0).

I asked for help there. I will post back is they have any suggestion.

I imagine there is a reason why this feature is not part of the distribution...

Still I'm happy to test.

# dpkg -l | grep module-init
ii  module-init-tools                  3.12-1
tools for managing Linux kernel modules

I created the folder and then /etc/depmod.d/00-system.conf same like yours.

then I run "depmod -a" but lsmod shows the ath5k module is not loaded.

If I overwrite the original .ko files I get this error:
ath5k: version magic '3.0.0 SMP preempt mod_unload 486 ' should be
'3.0.0-voyage SMP preempt mod_unload 486 '

if you have other ideas, I'm happy to try them!

thank you,
alfonso

This is a good idea especially as I don't know anything of this
distribution and don't have it here for testing.

I hope you get some help there. Maybe man depmod or man depmod.conf
knows something more? E.g., I don't have a /etc/depmod.conf file. Maybe
you have one?


Good luck,
