rsu
— Realtek
RTL8188SU/RTL8192SU USB IEEE 802.11b/g/n wireless network device
rsu* at uhub? port ?
The rsu
driver supports USB 2.0 wireless
network devices based on Realtek RTL8188SU, RTL8191SU and RTL8192SU
chipsets.
The RTL8188SU is a highly integrated 802.11n adapter that combines a MAC, a 1T1R capable baseband and an RF in a single chip. It operates in the 2GHz spectrum only.
The RTL8191SU is a highly integrated multiple-in, single-out (MISO) 802.11n adapter that combines a MAC, a 1T2R capable baseband and an RF in a single chip. It operates in the 2GHz spectrum only.
The RTL8192SU is a highly integrated multiple-in, multiple-out (MIMO) 802.11n adapter that combines a MAC, a 2T2R capable baseband and an RF in a single chip. It operates in the 2GHz spectrum only.
These are the modes the rsu
driver can
operate in:
The rsu
driver can be configured to use
Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA1 and WPA2).
WPA2 is the current encryption standard for wireless networks. It is
strongly recommended that neither WEP nor WPA1 are used as the sole
mechanism to secure wireless communication, due to serious weaknesses. WPA1
is disabled by default and may be enabled using the option
"wpaprotos
wpa1,wpa2". For standard WPA networks which use
pre-shared keys (PSK), keys are configured using the
"wpakey
" option. WPA-Enterprise networks
require use of the wpa_supplicant package.
The rsu
driver can be configured at
runtime with ifconfig(8) or on boot
with hostname.if(5).
The driver needs at least version 1.1 of the following firmware file, which is loaded when an interface is attached:
A prepackaged version of the firmware can be installed using fw_update(1).
The following adapters should work:
The following example scans for available networks:
# ifconfig rsu0 scan
The following hostname.if(5) example configures rsu0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:
nwid mynwid wpakey mywpakey dhcp
arp(4), ifmedia(4), intro(4), netintro(4), usb(4), hostname.if(5), ifconfig(8)
The rsu
driver first appeared in
OpenBSD 4.9.
The rsu
driver was written by
Damien Bergamini
<damien.bergamini@free.fr>.
The rsu
driver does not support any of the
802.11n capabilities offered by the adapters. Additional work is required in
ieee80211(9) before those features can
be supported.
This driver does not support powersave mode.
