ath5k master (AP) mode

ath5k master (AP) mode

[RUMI Szabolcs]

Hello!

I've been trying to set an Atheros NIC to AP mode using the ath5k
driver but it fails:

# iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Invalid argument.

First I've tried this with the driver version that is included with 2.6.27
but when I saw that it doesn't work I have installed the compat-wireless
tarball from today (2008-11-12) but it still doesn't work.

Is this how it supposed to be (eg. not supported yet) or am I just doing
something wrong?

Thanks,

You need to use hostapd for master mode.

Well, I have installed hostapd-0.6.5 with the nl80211 driver and it says:

# hostapd -dd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
ctrl_interface_group=0

Some news about what I have tried since yesterday:

I have compiled a kernel from wireless-testing git of today (2.6.28-rc4-wl)
then recompiled and tested hostapd-0.6.5 against that, but it exhibited the
same behavior as above. Then I've compiled libnl git of today which did
compile but any version of hostapd failed to compile against it so I gave
up on that. Then I have compiled the hostapd git of today against libnl-1.1
and the wireless-testing kernel which did compile but runtime it exhibited
the same error as above. So basically whatever I do it fails to set master
mode on ath5k...

I have also tried to patch 2.6.27 with a patch that the OpenWRT people
seemed to be using and has this in net/mac80211/cfg.c:

@@ -33,6 +33,10 @@ nl80211_type_to_mac80211_type(enum nl802
       case NL80211_IFTYPE_MESH_POINT:
              return IEEE80211_IF_TYPE_MESH_POINT;
#endif
+      case NL80211_IFTYPE_AP:
+              return IEEE80211_IF_TYPE_AP;
+      case NL80211_IFTYPE_AP_VLAN:
+              return IEEE80211_IF_TYPE_VLAN;

But this also ended up with the same error like anything else.

If you look a bit further down in that email, I've also tried
exactly that afterwards but unfortunately it made no difference.

BTW I've made a diff -rduN between hostapd-0.6.5 and todays -git
but haven't spotted anything relevant to my problem anyway.

To summarize:

2.6.27 + hostapd-0.6.5 = NO
2.6.27 + OpenWRT hack + hostapd-0.6.5 = NO
compat-wireless-2008-11-12 + hostapd-0.6.5 = NO
wireless-testing-git + hostapd-0.6.5 = NO
wireless-testing-git + hostapd-git = NO

In fact I've also tried hostapd-0.6.4 and 0.5.10 at some point
but they didn't make anything better.

Thanks,

Sab

ath5k is at fault; I think there were patches but I know nothing about
ath5k

        hw->wiphy->interface_modes =
                BIT(NL80211_IFTYPE_STATION) |

Have you enabled AP mode on the driver ?

should work but we still need to test it)

YES, that did the trick! :)
With partial success. To summarize:

- Open System worked (only basic IPv4 tested, eg. ICMP ping)
- MAC filtering from hostapd didn't work
- WEP didn't work
- WPA and WPA2 weren't tested

I have attached a hostapd log (concatenated, commented, and gzipped)
of my testing runs.

In the end I need this to work properly as an AP with WPA2
so I'm willing to test further if somebody is willing to try to
fix the whole thing...

Thanks,

Sab

Re: ath5k master (AP) mode

Hello Everyone!

To put it simple: IT WORKS! :)

The recipe:

wireless-testing-git pull from earlier today with the only
modification being this:

-----8<----------------------------------------

--- wireless-testing/drivers/net/wireless/ath5k/base.c      2009-02-10 06:11:43.186470883 +0100

        hw->extra_tx_headroom = 2;

-----8<----------------------------------------

Otherwise hostapd-0.6.7, nothing special on the userland.

In detail:

- Open System mode works with Tx fluctuating between 4-6 Mbps
and Rx between 10-14 Mbps regardless of the distance or signal
strength. It was tested standing 1m away from the AP antenna
(signal 100/100) up to 15m away with several thick walls in
between (signal 60/100) but throughput figures remained the
same.

- MAC address filtering does work. It probably always did,
I think I've just messed up the configuration the last time
and that was the reason back then, sorry.

- WEP mode does not work, apparently the driver does not allow
setting it and hostapd is exiting on that error.

- WPA and WPA2 have been tested and they seem to be working!

A small hint is that the WPA pre-shared key should be given
in hex both for hostapd and on the clients, otherwise there can
be differences in translation from ASCII to hex which in turn
may lead to an authentication failure.

I've tried to push some 100 MBs through the link in both directions
both with WPA/WPA2 turned off and then on and it seems to be rock
solid so far. CPU usage both on the AP host and the client is
negligible in any case, the throughput isn't affected by turning
on WPA/WPA2 either.

Thank you all!

Best regards,
Sab

The only reason we haven't enabled AP support yet is that it didn't
work on some devices and we need to make more tests to be sure that
it's ok.

I found a blog entry from Jiri saying he had it working on the AR5212,
but I'm unable to reproduce his luck.  I only added the patch to enable
AP mode, assuming the rest are already in the wireless-testing tree.

My NIC:
16:00.0 Ethernet controller: Atheros Communications, Inc. AR5212/AR5213 Multiprotocol MAC/baseband processor (rev 01)

As long as I leave channel=0, I don't see any obvious errors when I start hostapd,
but I don't see any APs show up on a friend's Vista system (or my G1).  If I try
to set a channel (channel=1, for instance), then it fails to set the channel and aborts.

I haven't used hostapd before, so I could be messing that up somehow.  I'm trying
the latest git snapshot as of today, and the libnl-1.1


Here is my hostapd startup, in case it helps:

[root@ibmt60w-1 hostapd]# ./hostapd -d hostapd_ath5k.conf
Configuration file: hostapd_ath5k.conf

Just to finish the thread. After all the issues I had I decided to
wait until all patches make it into the official tree. Yesterday I've
downloaded the latest compat-wireless, hostapd 0.6.9, installed it and
everything worked out of the box, including open mode and WPA and on
both WM6 smartphone and WM5 pocket pc. And that's on 2.6.27-14 kernel
(currently latest ubuntu kernel). Thanks everybody for the great work!

The problem is not that WPA does not work. It works for my WM6 client
(who connects with or without WPA from some 2nd or 3rd attempt but
cannot browse anything anyway even without encryption) but does not
work for WM5 client (who can browse but only when it connects and it
only connects with WPA disabled). Not sure which component to blame
here. Both devices work so nicely with WPA with hardware wireless
router :)

I guess I'll just wait for future versions of driver and kernel and
keep upgrading hoping that it'll start working.

It's possible ath5k has bugs in the crypto for AP mode like the ones fixed
in ath9k recently - you can always try the nohwcrypt=1 modparam.

I can't be sure. I don't have the unstable connection problem but I didn't
use WPA yet. So maybe the unstable connection problem only happens with WPA.

The client was Linux 2.6.29-rc6 with a USB WiFi key with the rtl8187L chipset.

Thanks. This link is broken however simple search brings me here:
http://wireless.erley.org/
where the author says that Atheros AR5213A does not work: "Lets me set
master mode, and activate hostapd, but not found on other machines
while scanning". Well what I tried is I left the kernel on 2.6.27-13,
compiled latest compat-wireless, upgraded to hostapd 0.6.8 and I got
hostapd starting successfully. I configured it for open system and got
my Windows Mobile 5 PDA connecting to it successfully and even
interenet was working! WM6 Smartphone connects from 2nd or 3rd attempt
but has no access to internet for some reason. With WPA2-PSK WM6
connects but still no internet and WM5 does not connect even though
the config is pretty standard:
wpa=3
wpa_passphrase=abcdefgh
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP

Does this resemble your wpa configuration?

Do you know, if I got this far, can unstable connection and not
working WPA be related to older kernel?
What clients did you try? I can't understand why internet access works
on WM5 but not on WM6. Both devices worked great with hardware
wireless router.

Hi,

Yes, the driver option value is nl80211. This is the patch you are looking for I think:

I think that would need a new Wireless Extensions feature, and WExt is
closed for new features, as we are transitioning to cfg80211.

Seems like iwconfig should have a more useful error message,
telling users to use hostapd for this particular driver,

Hostapd needs to be used for master mode in *any* case.  So yes, its
intended that you need hostapd for master mode with mac80211 drivers.
Just switching the card to master mode simply won't work, because
there's oh-so-much-more setup required in addition to that, which
hostapd knows how to do.

I don't know if it's intended, or just not implemented, but iwconfig <iface> mode master
won't work with mac80211 drivers.  Hostapd knows how to set master mode on it's own.

I use 2.6.29-rc6 and hostapd 0.6.8. I know that on kernels < 2.6.29 you need another patch to enable AP support, not just the one that enables AP support in ath5k. If you upgrade to 2.6.29 the old regulatory rules will be disabled by default. So unless you re-enable them (but I haven't tested with that) you'll have to install crda and the wireless regulatory database. In hostapd.conf you will have to change channel=0 to something else.

to indicate that it's the same matter I use the same subject. I am
trying to make my "04:01.0 Ethernet controller: Atheros Communications
Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01)" which is

I am also trying to get ath5k Master/AP mode working with my wireless card.

I am using a GIGABYTE GN-WS50G 802.11 b/g Atheros AR5007 chipset
minicard mPCI express.

It gets detected as PCI ID: 168c:001c. I am using Ubuntu 8.10.

I downloaded the latest tarball from
http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2
and then patched the single file adding in the option for AP mode. I
unloaded the ath5k module and then reloaded it using modprobe. However
I am still getting the "SET failed on device wlan0 ; Invalid
argument."

Using hostapd 0.6.7 I see the errors:

Failed to set interface wlan0 to master mode.
nl80211 driver initialization failed

Trying to figure out what I am missing.

Arrrrg,
as i understood it, the newest pull did change that line, so i did not.
With that line added hostapd starts, and at first look, a bg2200 sees
the accesspoint with wpa2 capability.

Sorry for that.

I can confirm Norman's wireless card's behavior (and have an associate =
with
the same problem).  This is with the upthread patch applied to compat-w=
ireless
pulled from git.

ath5k 0000:0a:05.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
ath5k 0000:0a:05.0: registered as 'phy5'
phy5: Selected rate control algorithm 'pid'
ath5k phy5: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43)
ath5k phy5: RF5112B multiband radio found (0x36)

If I remove the entry from hostapd.conf to set the channel, and force a=
 channel
with iwconfig, hostapd will start, but nothing can associate, and netst=
umbler
on an XP machine with an atheros card in it does not detect the SSID as=
 being=20
an access point.
