+.Tn Netwave AirSurfer Wireless LAN interface
+.Sh SYNOPSIS
+.Cd "cnw0 at pcmcia?"
+.Sh DESCRIPTION
+The
+.Nm cnw
+interface provides access to a theoretical 1 Mb/s wireless ethernet network
+based on the Netwave AirSurfer Wireless LAN (formerly known as the Xircom
+Netwave Wireless LAN).
+It use 32K of I/O memory mapped to the card along with either 16 I/O ports
+or 4K of additional I/O memory for access to command registers. The
+driver currently only supports the use of the additional 4K of I/O memory.
+.Pp
+In use, the cards appear to achieve up to a 420Kb/s transfer rate, though
+a transfer rate between 250Kb/s and 350Kb/s is typical. The card
+operates in the 2.4Ghz frequency range and is subject to interference
+from microwaves as well as earth.
