rtw
— Realtek
RTL8180L IEEE 802.11b wireless network driver
rtw* at cardbus? function ?
rtw* at pci? dev ? function ?
The 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, though not all of them are currently supported.
These are the modes the rtw
driver can
operate in:
rtw
supports software WEP. Wired
Equivalent Privacy (WEP) is the de facto encryption standard for wireless
networks. It can be typically configured in one of three modes: no
encryption; 40-bit encryption; or 104-bit encryption. Unfortunately, due to
serious weaknesses in WEP protocol it is strongly recommended that it not be
used as the sole mechanism to secure wireless communication. WEP is not
enabled by default.
The rtw
driver can be configured at
runtime with ifconfig(8) or
on boot with
ifconfig.if(5) using the
following parameters:
bssid
bssid-bssid
chan
n-chan
media
mediartw
driver supports the following
media types:
autoselect
DS1
DS2
DS5
DS11
mediaopt
optsrtw
driver supports the following media
options:
-mediaopt
optsssid
idrtw
driver uses an empty string. Note that network
ID is synonymous with Extended Service Set ID (ESSID).nwkey
keyrtw
is capable of using both 40-bit (5 characters
or 10 hexadecimal digits) or 104-bit (13 characters or 26 hexadecimal
digits) keys.-nwkey
nwkey
persist

The following ifconfig.if(5) example creates a host-based access point on boot:
inet 192.168.1.1 255.255.255.0 NONE media autoselect \ mediaopt hostap ssid my_net chan 11
Configure rtw0 for WEP, using hex key “0x1deadbeef1”:
# ifconfig rtw0 nwkey 0x1deadbeef1
Return rtw0 to its default settings:
# ifconfig rtw0 -bssid -chan media autoselect \ ssid "" -nwkey
Join an existing BSS network, “my_net”:
# ifconfig rtw0 192.168.1.1 netmask 0xffffff00 ssid my_net

The rtw
device driver first appeared in
NetBSD 3.0 and then in OpenBSD
3.7.
The rtw
driver was written by
David Young ⟨dyoung@NetBSD.org⟩ and
ported to OpenBSD by Jonathan
Gray
<jsg@openbsd.org>, who
wrote this man page.
Only the Philips SA2400A and Maxim MAX2820 RF transceivers are known to work. Devices incorporating a GCT RF transceiver are not supported due to a lack of documentation from GCT.
While PCI devices will attach most of them are not able to transmit.
