I've been testing the new driver on w8.1 x64 with intel N2230 wireless card.
Still the same problems as before, connection drops ( not as much but still there ), connection alive but no communication and a few minutes ago while watching a movie Wifi froze completely. A restart of the computer did not work. Had to power off and boot from scratch to enable it again.
Wifi seems more stable while on power cord than on battery.
So Wifi is still not usable.
