rtw —
rtw* at cardbus? function ?
rtw* at pci? dev ? function ?
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.
rtw driver can be configured at runtime with
ifconfig(8) or on boot with
ifconfig.if(5) using the
following parameters:
bssid
bssid-bssidchan
n-chanmedia
mediartw driver supports the following
media types:
autoselectDS1DS2DS5DS11mediaopt
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.-nwkeynwkey

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”:

rtw device driver first appeared in
NetBSD 3.0 and then in OpenBSD
3.7.
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.
While PCI devices will attach most of them are not able to transmit.
