Does this CMOS assumption apply to ath5k as well? I thought ath5k has noise recalibration which tune the noise floor accordingly (which seems to be true from our experiments). In madwifi the noise floor is fixed at -95 or -96, but the ath5k introduces the ani and noise recalibration. But the

Hi, I meant the number of actual antenna was used. I am not sure whether it has the same antenna setting in /sys/kernel/debug/ieee80211 like ath5k. regards; Peizhao On 15/02/11 19:10, Sagar Bijwe wrote: I would also like to know that... -Sagar On Tue, Feb 15, 2011 at 2:35 PM, Baldomero

Hi I am wondering whether this problem is due to the OpenWRT or an issue of the ATH9k. ---[ cut here ] WARNING: at /root/openwrt-svn-repo/routerStation/active_trunk/build_dir/linux-ar71xx_generic/compat-wireless-2010-11-20/drivers/net/wireless/ath/ath9k/recv.c:532

Hi, The firmware was built using OpenWRT svn trunk 24136 that uses compat-wireless-2010-11-20 and 2.6.36.1 kernel. The warning message comes right after I configured the radio and bring it up in adhoc mode. regards, Peizhao On 25/11/10 15:05, Mohammed Shafi wrote: On Thu, Nov 25, 2010 at
