I got:
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 2147M 100 2147M 0 0 2246k 0 0:16:18 0:16:18 --:--:-- 1842k
real 16m18.774s

sys 0m36.350s
This is ~ 17.55Mbit/s for file transfer.
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?
