AP in 11ng mode:
media: IEEE 802.11 Wireless Ethernet autoselect mode 11ng <hostap>
status: running
ssid home.serebryakov.spb.ru channel 9 (2452 MHz 11g ht/20) bssid f4:ec:38:a3:10:6d
But client 802.11g only (Intel 3945ABG)

Maybe, it is possible to add additional debug output in such situations? I'm not able to run `athstat' ASAP manually in most of these cases, because I didn't look at notebook's screen when copy files to it and notice such situations post-factum.
