Hello,

Is any configuration of the wireless standards to be used available? eg. 
use only b, disable n etc.


Thanks,
Eric

Can you please elaborate. I could not understand.
with ath9k you cannot set 'b' mode or 'a' mode via iw/iwconfig commands

[Sagar Bijwe]

Hi,
I am a newbie to ath9k drivers. Setting rates to 54M using iwconfig is not
working for ad-hoc mode. I could see only 1 Mbps throughput using iperf. Any
hint over this???

have not tested  iperf with ad-hoc, ad-hoc is limited to legacy and
handled by mac80211 protocol stack. is this working fine in station
mode ?

[ath9k-devel] Set wireless standard

[Sagar Bijwe]

I didnt test it in station mode but i am desperately in the need of setting
up a wireless test-bed of a few nodes in ad-hoc mode.
For my research, i want to disable backoff as well as physical and virtual
carrier sense. I have currently set cwmin and cwmax to 0 and AIFS to 1
(imitate beacon) to disable the backoff. To test this i guess ad-hoc mode is
suitable. I am looking for insights into which modes and rates are supported
over ath9k chipsets and how multiple antennas will have impact over my
experimentation.
Thanks

To clarify, of 802.11[a,b,g,n] is there any way to disable, say, 802.11n?

For example, some other driver allows disabling of 802.11n by passing a 
parameter to the module upon loading.

Thanks,
Eric

Please do a hack in hw.c of ath9k

1872         if (ah->config.ht_enable)
1873                 pCap->hw_caps |= ATH9K_HW_CAP_HT;
1874         else
1875                 pCap->hw_caps &= ~ATH9K_HW_CAP_HT;

delete lines 1872, 1873, 1875

thanks,
shafi

The problems is adhoc is limited to only legacy rate and the HT patch
for IBSS is not yet officially merged. And I doubt will ath9k rate
control to be any effect for IBSS.

>>HT patch for IBSS is not yet officially merged
Does that mean if at least I disable 11n  with the suggested patch and use
b/g mode, I should be able to get the rate of 11/54Mbps with ad-hoc mode ???
