What is much, much better. Thank you. Are these changes(3.16 [slow b43] vs 3.18 [fast b43]) located in drivers/net/wireless/b43? I would like to port them(changes) to my 3.16 kernel. By the way, during test connection was hang, and I can not ping any machine outside of my notebook. I rmmod/modprobe b43, restart wpa_supplicant/dhcpcd and all back to normal. And after restart I was unable to reproduce it(bug). dmesg also show nothing. Any hints how to debug such kind of issues, if I see it again? -- /Evgeniy
