rtw
driver supports PCI/CardBus 802.11b wireless
adapters based on the Realtek RTL8180L.
A variety of radio transceivers can be found in these devices, including the Philips SA2400A, Maxim MAX2820, and GCT GRF5101.
These are the modes the rtw
driver can
operate in:
The rtw
driver can be configured to use
software Wired Equivalent Privacy (WEP). It is strongly recommended that WEP
not be used as the sole mechanism to secure wireless communication, due to
serious weaknesses in it.
The rtw
driver can be configured at
runtime with ifconfig(8) or on boot
with hostname.if(5).

# ifconfig rtw0 scan
The following hostname.if(5) example configures rtw0 to join network “mynwid”, using WEP key “mywepkey”, obtaining an IP address using DHCP:
nwid mynwid nwkey mywepkey dhcp
The following hostname.if(5) example creates a host-based access point on boot:
mediaopt hostap nwid mynwid nwkey mywepkey inet 192.168.1.1 255.255.255.0

rtw
device driver first appeared in
OpenBSD 3.7.
rtw
driver was written by David

and ported to OpenBSD by Jonathan
Gray

While PCI devices will attach most of them are not able to transmit.
Host AP mode doesn't support power saving. Clients attempting to use power saving mode may experience significant packet loss (disabling power saving on the client will fix this).
