24 To compile this driver into the kernel,
25 place the following lines in your kernel configuration file:
26 .Bd -ragged -offset indent
35 Alternatively, to load the driver as a module at boot time,
36 place the following line in
38 .Bd -literal -offset indent
44 driver supports USB 2.0 wireless network devices based on the Atheros
47 The Atheros AR9170 is a draft-802.11n adapter that uses an external
48 radio to operate in either 2.4GHz only or 2.4GHz and 5GHz.
50 The AR9101 radio supports 1T1R operation in 2GHz only.
52 The AR9102 radio supports 2T2R operation in 2GHz only.
54 The AR9104 radio supports 2T2R operation both 2GHz and 5GHz.
56 These are the modes the
58 driver can operate in:
59 .Bl -tag -width "IBSS-masterXX"
63 mode, this is used when associating with an access point, through
64 which all traffic passes.
65 This mode is the default.
70 driver can be configured to use
71 Wired Equivalent Privacy (WEP) or
72 Wi-Fi Protected Access (WPA-PSK and WPA2-PSK).
73 WPA is the de facto encryption standard for wireless networks.
74 It is strongly recommended that WEP
75 not be used as the sole mechanism
76 to secure wireless communication,
77 due to serious weaknesses in it.
81 driver can be configured at runtime with
84 The driver needs at least version 1.0 of the following firmware files,
85 which is loaded when an interface is attached:
87 .Bl -tag -width Ds -offset indent -compact
