NAMErsu - Realtek RTL8188SU/RTL8192SU USB IEEE 802.11b/g/n wireless network device
SYNOPSISTo compile this driver into the kernel, place the following lines in your kernel configuration file:
device ehci device uhci device ohci device usb device rsu device wlan
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:
After you have read the license in /usr/share/doc/legal/realtek you will want to add the following lines to loader.conf5:
DESCRIPTIONThe ifconfig 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 ifconfig driver can operate in:
- BSS mode
- Also known as infrastructure mode, this is used when associating with an access point, through which all traffic passes. This mode is the default.
The ifconfig driver can be configured to use Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA-PSK and WPA2-PSK). WPA is the de facto encryption standard for wireless networks. It is strongly recommended that WEP not be used as the sole mechanism to secure wireless communication, due to serious weaknesses in it.
The ifconfig driver can be configured at runtime with ifconfig(8).
FILESThe driver needs at least version 1.2 of the following firmware file, which is loaded when an interface is attached:
HARDWAREThe ifconfig driver provices support for Realtek RTL8188SU/RTL8192SU USB IEEE 802.11b/g/n wireless network adapters, including:

- Belkin F7D1101 v1
- D-Link DWA-131 A1
- EDUP EP-MS150N(W)
- Hercules HWGUn-54
- Hercules HWNUm-300
- Planex GW-USNano
- Sitecom WL-349 v1
- Sitecom WL-353
- Sweex LW154
- TRENDnet TEW-648UB
- TRENDnet TEW-649UB
EXAMPLESJoin an existing BSS network (i.e., connect to an access point):
ifconfig wlan create wlandev rsu0 inet 192.168.0.20 \ netmask 0xffffff00
Join a specific BSS network with network name ``my_net ''
"ifconfig wlan create wlandev rsu0 ssid my_net up"
Join a specific BSS network with 64-bit WEP encryption:
ifconfig wlan create wlandev rsu0 ssid my_net \ wepmode on wepkey 0x1234567890 weptxkey 1 up
- "%s: failed load firmware of file rsu-rtl8712fw"
- For some reason, the driver was unable to read the microcode file from the filesystem. The file might be missing or corrupted.
- "device timeout"
- A frame dispatched to the hardware for transmission did not complete in time. The driver will reset the hardware. This should not happen.
