Product Information

Alfa wifi adapters became famous because of its quality and the power of the device. If you are working as a pentester and you need to do a audit to a wifi network, this device is a must have. That said, I ran into some issues with the default filter, so I had to create a blank filter with the proper values. With everything properly connected and configured, it was time to set up monitor mode. To do this, I started airmon-ng on the wlan0 device. root@kali: ~# airmon-ng start wlan0 Once I put the device properly in monitor mode, then I ran airodump! root@kali: ~# airodump-ng wlan0mon I connected both the H and the HA to an Engenius AP so I could monitor the signal level of both devices. This AP is about ¾ mile from me, and I am using just the standard 5db rubber antenna’s that ship with each unit.

The H was typically giving a signal strength, on the Engenius AP, of around -73 to -80. As low as -88db.I’m running into the same issue that James posted on November 15th. When I disconnect and reconnect the device manually then go to Devices>USB>Atheros, just as you suggested to James, I still receive the “failed to attach the USB device” warning. Sometimes retailers have a tendency to promote a specific attribute of a product as if it is the only thing that matters. In fact, while higher output is a good thing, it is not the only thing that determines your range and signal strength.

So in this case for example I shall type in "ifconfig wlan1 up" to reinstate. Compatibility: This is compatible with Windows XP, Vista, and Windows 7 out of box (software included on CD). Windows 10 drivers are not included on CD but can be found here . I thought that maybe it didn't have the right drivers so i tried to apt-get install firmware-atheros but it said that it was already installed.
