Could you also show dmesg lines printed when you plug in your athn device? This problem happens with both iwn and athn, does it? Please trigger this problem again and show the output of: netstat -n -I athn0 netstat -W athn0 netstat -n -I iwn0 netstat -W iwn0 Please also check if any of these commands make your problem disappear: ifconfig athn0 mode 11a ifconfig athn0 mode 11g ifconfig iwn0 mode 11a ifconfig iwn0 mode 11g > IMPORTANT: This system is freshly installed 6.6 without any changes to it > (except for installed packages).

It would good to know what model of AP you are using exactly. This kind of issue is very very hard to fix without being able to reproduce the problem locally. Perhaps I can find a similar AP somewhere.
