[ath9k-devel] 2.6.28-rc6: still can't set up AP mode

[ath9k-devel] 2.6.28-rc6: still can't set up AP mode

[Tamas Selmeci]

Hello all!

Today I again made a try with ath9k from linux-2.6.28-rc6 (and of course 
with wireless-testing cloned on 24-Nov-2008)

I'm using hostapd-0.6.6 (configured with nl80211), iw-0.9.6 and libnl-1.1.

With ath9k the station mode operates perfectly with both Ath5416 and 
Ath9160. The problem is the AP mode. By default, ath9k refuses to switch 
to AP mode, I suppose it is still under heavy development... but a patch 
found on 
http://johannes.sipsolutions.net/patches/kernel/all/2008-10-28-08%3a33/ 
(008-allow-ap-vlan-modes.patch) makes is possible to switch to AP mode.

My hostapd configuration file is the following:
---------------------------------
interface=wlan0
driver=nl80211
hw_mode=g
logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=2
debug=0
ctrl_interface_group=0
macaddr_acl=0
auth_algs=3
eapol_key_index_workaround=0
eap_server=0
dump_file=/tmp/hostapd.dump
wpa=3
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP
ssid=uwc_ap
wpa_psk=e757da617495f77f0a5b017c1d62eca6596adc36ab0955c5f6be7554b7a305d3
---------------------------------

And when running hostapd, it outputs:
---------------------------------
Configuration file: /tmp/dyncfg/hostapd.conf
Failed to update rate sets in kernel module
Failed to set CTS protect in kernel driver
Failed to set Short Slot Time option in kernel driver
Could not set preamble for kernel driver
Using interface wlan0 with hwaddr 00:1d:0f:b0:0e:ac and ssid 'uwc_ap'
Failed to set CTS protect in kernel driver
Failed to set Short Slot Time option in kernel driver
Could not set preamble for kernel driver
---------------------------------

Despite these, hostapd is still in the memory and running, but on my 
other PC the AP with the SSID can not be found.

My questions so far:
1) may I expect a working AP mode at the current state of ath9k? (I 
rememben formerly a few people reported that it works);
2) what am I doing wrong?
3) do I need CRDA? What is it good for at all (in a nuthsell) - links 
are also appreciated... The descriptions found in the tarball of CRDA 
and Linux wireless are not enough to make me understand what is it good 
for. I suspect that the lack of CRDA can cause that my new AP network 
cannot be seen.

Thanks,

Best regards,

AP mode is under development, and getting it to work right now is not
possible.

Im trying the same ting, AP mode with ath9k.
Im not an expert, but I have it working.
You could try to add this to your hostapd.conf:

1. If you are using the wifi interface in a bridge (lan/wifi), you have 
to add
    bridge=br0 to your config.

2. I cannot see that you have set any channel number, so add
    channel=6 or an other number to your config.

CRDA is for setting allowed channels/power in kernel userspace for your 
country.

That's it, after setting channel=9 in hostapd.conf the AP mode works, I 
can connect to the newly established AP. :)

[ath9k-devel] Possible Bug Caps lock flashing laptop frozen

[Brian]

All,
I was going to put in a long spiel here but I thought I would check the
web first.
I found other people also have their laptops freeze with wireless issues
 and the caps lock flashing. Most think it is heat or memory related.

However, I have only had this problem since using the wireless-testing
kernel. So just a quick note, in case someone else has the same problem.

While the above statement is true, there was one other change I made at
the same time and that was to put the wireless N adapter in.
I think this must use a bit more power and my laptop must have been
marginal.
Anyway, read on the web that a possible solution was to remove the
battery. Did this and I have been running for a couple of hours with no
problems.
I even have my NX session running to control another machine which is
also wireless. So the wireless is working great and the response time is
instantaneous.

The other thing that has changed is that the adapter LEDs are now
flashing, they were on solid before.
