rsu — Realtek
RTL8188SU/RTL8192SU USB IEEE 802.11b/g/n wireless network device
rsu* at uhub? port ?
rsu driver supports USB 2.0 wireless
network devices based on Realtek RTL8188SU, RTL8191SU and RTL8192SU
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
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
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 adapter needs firmware files to run, which are loaded on demand by the driver when the device is attached:
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:
join mynwid wpakey mywpakey inet autoconf

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
This driver does not support powersave mode.
