In-Depth Information
The following web page lists good information about the various brands of Wi-Fi
adapters available and their level of support:
I have a NetGear WN111(v2) RangeMax Next Wireless adapter available. Apparently,
this adapter uses one of the following chips:
•
Atheros AR9170
•
Atheros AR9101
Since the AR9170 shows up in the supported list for the D-Link DWA-160, there is
a reasonable chance of driver support for it. After plugging it into the powered USB hub
and rebooting, the console log shows that it is being “
seen
”:
$ dmesg
. . .

[6.687035] usb 1_1.3.2: firmware not found.
[7.703098] usb 1_1.3.2: kill pending tx urbs.
But there is a troubling error message: “firmware not found.” Also visible in the log,
we see that the driver is named
carl9170
. Further research reveals that it also requires a
firmware file named
carl9170-1.fw
. While this file is available from other sources, the
simplest way to install this file is to install it from Raspbian sources:
$ sudo apt-get install firmware-linux
The firmware file being sought and installed is as follows:
$ ls -l /lib/firmware/carl9170−1.fw
−rw−r−−r−−1 root root 13388 Jan 14 17:04 /lib/firmware/carl9170−1.fw
