Szymon, this is a damn late reply and I think I understand if you've
already switched to some other card.

In case you're still using b43 & BCM4318: did you manage to fix this
problem yourself?

If you didn't, can you do some tests for me?
1) Start your ftp copying, wait for connection to die, and perform "iw
dev wlan0 scan" (replace wlan0 if you have different interface). Do
you get any scanning results?
2) Does switching from DMA to PIO help? (modprobe -r b43 && modprobe b43 pio=1)
