+.Sh NAME
+.Nm cnw
+.Nd
+.Tn Netwave AirSurfer Wireless network driver
+.Sh SYNOPSIS
+.Cd "device cnw"
+.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).
+.Pp
+Note that the driver does not support newer devices
+such as the Netwave AirSurfer
+.Dq Plus ,
+or the BayStack 650/660.
+These devices are supported by the
+.Xr awi 4
+driver.
+.Pp
+Netwave devices are not compatible with IEEE 802.11 wireless network.
+Also note that there are Netwave devices with different wireless frequency,
+depending on radio band plan in each countries.
+.Pp
+The card uses 36K of I/O memory mapped to the card.
+You may need to increase memory space available to the PCMCIA controller.
+See
+.Xr pcmcia 4
+for details.
+.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.
+.Pp
+The card operates in the 2.4GHz frequency range and is subject to interference
+from microwaves, IEEE 802.11 wireless network devices, as well as earth.
+For example, it seems that IEEE 802.11 channel 14 conflicts with Netwave
+.Pq US frequency .
+They interfere each other if we operate both of them
+in the same geographic region, causing weird packet loss.
+You may be able to avoid the interference with IEEE 802.11 devices,
+by changing IEEE 802.11 channel.

+for BSDI.
+It was ported to NetBSD by
+.An Michael Eriksson.
