40 .Nd ZyDAS ZD1211/ZD1211B USB IEEE 802.11b/g wireless network device
42 To compile this driver into the kernel,
43 place the following lines in your
44 kernel configuration file:
45 .Bd -ragged -offset indent
52 .Cd "device wlan_amrr"
55 Alternatively, to load the driver as a
56 module at boot time, place the following line in
58 .Bd -literal -offset indent
64 driver provides support for wireless network adapters based around
65 the ZyDAS ZD1211 and ZD1211B USB chips.
67 These are the modes the
69 driver can operate in:
70 .Bl -tag -width "IBSS-masterXX"
74 mode, this is used when associating with an access point, through
75 which all traffic passes.
76 This mode is the default.
78 In this mode the driver is able to receive packets without
79 associating with an access point.
80 This disables the internal receive filter and enables the card to
81 capture packets from networks which it wouldn't normally have access to,
82 or to scan for access points.
86 supports software WEP.
87 Wired Equivalent Privacy (WEP) is the de facto encryption standard
88 for wireless networks.
89 It can be typically configured in one of three modes:
90 no encryption; 40-bit encryption; or 104-bit encryption.
91 Unfortunately, due to serious weaknesses in WEP protocol
92 it is strongly recommended that it not be used as the
93 sole mechanism to secure wireless communication.
94 WEP is not enabled by default.
96 The following devices are known to be supported by the

168 .It "zyd%d: could not load firmware (error=%d)"
169 An error occurred while attempting to upload the firmware to the onboard
170 microcontroller unit.
171 .It "zyd%d: could not send command (error=%s)"
172 An attempt to send a command to the firmware failed.
173 .It "zyd%d: sorry, radio %s is not supported yet"
174 Support for the specified radio chip is not yet implemented in the driver.
175 The device will not attach.
176 .It "zyd%d: device version mismatch: 0x%x (only >= 43.30 supported)"
177 Early revisions of the ZD1211 chipset are not supported by this driver.
178 The device will not attach.
179 .It "zyd%d: device timeout"
180 A frame dispatched to the hardware for transmission did not complete in time.
181 The driver will reset the hardware.
182 This should not happen.
