Re: [ath9k-devel] AP + IBSS in different ath9k versions

2011-08-26 Thread gtolon

Thank you very much. I'll try that way and see what happens.

Best regards

 Hey Gabriel,

 Openwrt already uses compat-wireless by default when you select the
 ath9k driver.  The version is defined in the makefile for mac80211:
 https://dev.openwrt.org/browser/trunk/package/mac80211/Makefile

 I've never tried to build in a version other than what's defined by
 default, but I don't see why you couldn't change it to point at a
 custom/prerelease version.

 Hi Keith, i want to start using openwrt. I've been reading the wiki
 and documentation from openwrt.org http://openwrt.org and i found
 how to build different drivers and packages using svn and
 menuconfig, but i haven't found how to build compat-wireless. I
 would appreciate some help on this topic. Thank you

 Not sure if this is useful info, but seeing this thread I just tried

 creating an ap+adhoc device with openwrt on a linksys wrt160nl (
 atheros
 9xxx, compat-wireless 2011-06-22,   2.6.39.2 kernel, openwrt 27724).

 I created the interfaces using openwrt's uci abstraction.  Both
 virtual
 interfaces work fine.  I get G+ speeds (24-25Mbps, real) on the
 adhoc
 alone, 11Mbps from a STA all the way through and 28Mbps STA-AP.

 The only thing I noticed that was strange is that hiding the
 ESSID for
 the adhoc network had no effect (SSID was still advertised)

 Ok, i guess i can find that commits and comments on the

 git. i´ll dig into the code and the 80211 standard to
 analyze the
 beaconing problem also. Your answers have been very useful.

   Thank you for your answer. I´ll put it in two different cases:
  
 1) with the ath9k driver with comes with compat wireless
 2.6.39-1:
  
   Yes, like you said that ´s the message i get from dmesg when
 i try to
   create the ad-hoc interface after another interface is up.
 However if i
   first create the ad-hoc interface then i can bring up the
 original wlan0
   and run hostapd on it. But when i try to create an IBSS with
 ibss join i
   get device or resource bussy. I don´t know why the order of
 interface
   creation/bringing up is important in this case.
   this check might be missing there

ath9k: deny new interface addtion on IBSS mode
  
The present check denies the IBSS interface addtion if we
already have any other vifs. But it fails to deny interface
addition if IBSS was already present.

 2) with older ath9k versions, for example compat wireless
 2.6.32-16:
  
   In this case i can run hostapd in wlan0 and then create and
 bring up an
   ad-hoc interface without problems, furthermore i can join to an
 ibss with
   iw ibss join and all works fine.

   The main doubt i have is why the case 2) is not supported
 anymore, if is
   something wrong about 

[ath9k-devel] Maximum Radio Limit?

2011-08-26 Thread Galen
Provided that enough PCIe ports are available, along with sufficient memory and 
CPU, is there any limit to the number of radios that can be supported by ath9k 
and mac80211? Are there any design bottlenecks in the software that would be 
problematic in the context of a system with 100s of ath9k radio modules from 
being active simultaneously?

[ath9k-devel] Hot Plug / Hot Swap Support?

2011-08-26 Thread Galen
Is it possible to add and/or remove ath9k-supported radio modules without 
reloading compat-wireless? The ideal arrangement in this context would be to 
have multiple radio modules installed in a single system and then selectively 
add and/or remove one module at a time without disrupting connectivity for the 
other active modules.

Any thoughts? If this is not implemented, any idea how difficult this would be 
to make happen?
