23 .Nd Realtek RTL8188SU/RTL8192SU USB IEEE 802.11b/g/n wireless network device
25 To compile this driver into the kernel,
26 place the following lines in your kernel configuration file:
27 .Bd -ragged -offset indent
36 Alternatively, to load the driver as a module at boot time,
37 place the following line in
39 .Bd -literal -offset indent
43 After you have read the license in /usr/share/doc/legal/realtek
44 you will want to add the following lines to
46 .Bd -literal -offset indent

53 driver supports USB 2.0 wireless network devices based on Realtek
54 RTL8188SU, RTL8191SU and RTL8192SU chipsets.
56 The RTL8188SU is a highly integrated 802.11n adapter that combines
57 a MAC, a 1T1R capable baseband and an RF in a single chip.
58 It operates in the 2GHz spectrum only.
60 The RTL8191SU is a highly integrated multiple-in, single-out (MISO)
61 802.11n adapter that combines a MAC, a 1T2R capable baseband and an

70 These are the modes the
72 driver can operate in:
73 .Bl -tag -width "IBSS-masterXX"
77 mode, this is used when associating with an access point, through
78 which all traffic passes.
79 This mode is the default.
84 driver can be configured to use
85 Wired Equivalent Privacy (WEP) or
86 Wi-Fi Protected Access (WPA-PSK and WPA2-PSK).
87 WPA is the de facto encryption standard for wireless networks.
88 It is strongly recommended that WEP
89 not be used as the sole mechanism
90 to secure wireless communication,
91 due to serious weaknesses in it.
95 driver can be configured at runtime with
100 The driver needs at least version 1.2 of the following firmware file,
101 which is loaded when an interface is attached:
103 .Bl -tag -width Ds -offset indent -compact
104 .It /boot/kernel/rsu-rtl8712fw.ko
