Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):
if_rsu_load="YES" rsu-rtl8712fw_load="YES"
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:
| 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. |
| monitor mode | In this mode the driver is able to receive packets without associating with an access point. This disables the internal receive filter and enables the card to capture packets from networks which it wouldn't normally have access to, or to scan for access points. |
The rsu 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 rsu driver can be configured at runtime with ifconfig(8).

The driver needs at least version 1.2 of the following firmware file, which is loaded when an interface is attached:
| /boot/kernel/rsu-rtl8712fw.ko | |

Join a specific BSS network with network name "my_net":

Join a specific BSS network with 64-bit WEP encryption:

| %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. |
The rsu driver does not capture management frames in non-monitor modes; without this limitation some firmware functions (e.g., 'join bss') will not work properly.
