iwn driver drops with error: "firmware error 'iwn_intr: fatal firmware error'"
The iwn driver will drop the net connection after a couple of minutes use, rendering the internet unusable. error message: "iwn_intr: fatal firmware error". My wireless card is Intel Ultimate-N 6300 (which is listed as supported by the iwn driver). Internet works again temporarily after a '/etc/rc.d/netif restart', but only until the connection drops again.
