NAME
otus -- Atheros USB IEEE 802.11a/g/n wireless network device SYNOPSIS
otus* at uhub? port ? DESCRIPTION
The otus driver supports USB 2.0 wireless network devices based on Atheros Communications AR9001U chipset. The AR9001U chipset is made of an AR9170 MAC/Baseband and an AR9101 (1T2R), AR9102 (2T2R) or AR9104 (dual-band 2T2R) Radio. These are the modes the otus 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 otus 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 otus driver can be configured at runtime with ifconfig(8) or on boot with ifconfig.if(5). FILES
The driver needs at least version 1.0 of the following firmware files, which are loaded when an interface is attached: /libdata/firmware/if_otus/otus-init /libdata/firmware/if_otus/otus-main Although these firmware files are freely redistributable, their usage is restricted. HARDWARE
The following adapters should work: Arcadyan WN7512 CACE AirPcap Nx D-Link DWA-130 rev D1 D-Link DWA-160 rev A1 D-Link DWA-160 rev A2 IO-Data WN-GDN/US2 NEC Aterm WL300NU-G Netgear WNDA3100 Netgear WN111 v2 Planex GW-US300 SMC SMCWUSB-N2 TP-Link TL-WN821N Ubiquiti SR71 USB Unex DNUA-81 Z-Com UB81 Z-Com UB82 ZyXEL NWD-271N EXAMPLES
The following ifconfig.if(5) example configures otus0 to join whatever network is available on boot, using WEP key ``0x1deadbeef1'', channel 11, obtaining an IP address using DHCP: nwkey 0x1deadbeef1 chan 11 dhcp Join an existing BSS network, ``my_net'': # ifconfig otus0 192.168.1.1 netmask 0xffffff00 nwid my_net To use WPA, see wpa_supplicant(8) and wpa_supplicant.conf(5). DIAGNOSTICS
otus%d: error %d, could not read firmware %s For some reason, the driver was unable to read the microcode file from the filesystem. The file might be missing or corrupted. otus%d: 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. SEE ALSO

The otus driver first appeared in OpenBSD 4.6. It was ported to NetBSD by Anon Ymous and first appeared in NetBSD 6.0. AUTHORS
The otus driver was written by Damien Bergamini <damien@openbsd.org> based on source code licensed under the ISC released in 2008 by Atheros Communications for Linux. CAVEATS
The AVM FRITZ!WLAN USB Stick N adapter is currently not supported. The otus driver does not support any of the 802.11n capabilities offered by the AR9001U chipset. Additional work is required in ieee80211(9) before those features can be supported. The otus driver also does not currently support EDCA as this is missing in the NetBSD network stack. The hooks for it are in the driver code. BSD

NAME
upgt -- Conexant/Intersil PrismGT SoftMAC USB IEEE 802.11b/g wireless network device SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device ehci device uhci device ohci device usb device upgt device wlan Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_upgt_load="YES" DESCRIPTION
The upgt driver supports the USB 2.0 Conexant/Intersil PrismGT series wireless adapters based on the GW3887 chipset. These are the modes the upgt 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. upgt supports software WEP. Wired Equivalent Privacy (WEP) is the de facto encryption standard for wireless networks. It can be typically configured in one of three modes: no encryption; 40-bit encryption; or 104-bit encryption. Unfortunately, due to serious weaknesses in WEP protocol it is strongly recommended that it not be used as the sole mechanism to secure wireless communication. WEP is not enabled by default. The upgt driver can be configured at runtime with ifconfig(8). FILES
This driver requires the upgtfw firmware to be installed before it will work. The firmware files are not publicly available. A package of the firmware which can be installed via pkg_add(1) is available: http://weongyo.org/project/upgt/upgt-firmware-2.13.1.0.tar.gz HARDWARE
The upgt driver supports USB 2.0 Conexant/Intersil PrismGT series wireless adapters based on the GW3887 chipset, among them: o Belkin F5D7050 (version 1000) o Cohiba Proto Board o D-Link DWL-G120 Cohiba o FSC Connect2Air E-5400 USB D1700 o Gigaset USB Adapter 54 o Inventel UR045G o Netgear WG111v1 (rev2) o SMC EZ ConnectG SMC2862W-G o Sagem XG703A o Spinnaker DUT o Spinnaker Proto Board EXAMPLES
Join an existing BSS network (i.e., connect to an access point): ifconfig wlan create wlandev upgt0 inet 192.168.0.20 netmask 0xffffff00 Join a specific BSS network with network name ``my_net'': ifconfig wlan create wlandev upgt0 ssid my_net up Join a specific BSS network with 64-bit WEP encryption: ifconfig wlan create wlandev upgt0 ssid my_net wepmode on wepkey 0x1234567890 weptxkey 1 up SEE ALSO
arp(4), netintro(4), usb(4), wlan(4), ifconfig(8) HISTORY
The upgt driver first appeared in OpenBSD 4.3. AUTHORS
The upgt driver was written by Marcus Glocker <mglocker@openbsd.org>. The hardware specification was reverse engineered by the people at http://www.prism54.org. CAVEATS
The upgt driver just supports the USB 2.0 devices (GW3887 chipset) but not the USB 1.0 devices containing the NET2280, ISL3880, and ISL3886 chipsets. Some further efforts would be necessary to add USB 1.0 support to the driver. BSD
