After Centos 6.4 to 6.5 update.<br />
<br />
1. /proc/net/hostap/wlan0 is now /proc/net/hostap/wlan%d/<br />
2. There is no more /sys/class/net/wlan0/wireless<br />
<br />
1. This caused, that many third party wireless scripts (e.g. <a href="http://www.mobilnews.cz/honza/wewimo">http://www.mobilnews.cz/honza/wewimo</a> [<a href="http://www.mobilnews.cz/honza/wewimo" target="_blank">^</a>]) stop to working.<br />
<br />
2. This caused, that the basic wireless stuff (/etc/sysconfig/network-scripts/ifup-wireless) in Centos stop to working, because the /etc/sysconfig/network-scripts/network-functions will use that file to check, if the net interface is wireless or not.
