(HW compatibility test) Wifi usb adaptor Techno'sN150

pc: devuan 6
wm : xfce
network manager: (to be filled)

I tested : Technoethical's N150 mini wifi@
For many years i have in my home turned towards using wired networking . The reasons  being :
1) having in many years tried various adaptors that have problems making the work reliably (even if most of them claimed also linux support).
2) being afraid of the emf pollution .
Anyway i had in my radar for many years technoethical and so i decided to buy and try Techno's N150 that claims a

It works with the free driver ath9k_htc (GNU GPL v2) and the free firmware for ath9k_htc (Clear BSD).

As for the open firmware i found:

• @ open-ath9k-htc-firmware.

• @ Announcement of the release in the @ ath9k_htc_fw emailing list.

• @ A nov/2011 datasheet of AR9271.

From little i've read it seems credit goes mainly to : Adrian Chadd and Luis R. Rodriguez

The T'sN150 page claims:

Using the latest versions of the kernel (3.0 or later), the adapter works out of the box when plugging it on USB, and you don't have to manually install the firmware anymore.

Well that doesnt hold in Devuan 6 's 6.12.74 kernel.

Initially plugging in various usb3 ports of my Devuan 6 PC  i didnt see any syslog messages (nothing!).
Plugging it in a usb2 port i show a $ lsusb entry :
Bus 003 Device 006: ID 0cf3:9271 Qualcomm Atheros Communications AR9271 802.11n

But after:
# apt-get install firmware-ath9k-htc firmware-atheros 
it works ok in either usb3 (blue) and usb2 (black) ports.

Also i dont know why but my adaptor came not with the fancy logo filled small sticker but with a simpler one with made in china and some small stuff that i  dont remember.

ps:
I am very curious how that happened. I mean what conditions and efforts allowed a company to accept to license openly a product's firmware.
Also i wonder it the firmware contain blobs.

Hello:

But after:

# apt-get install firmware-ath9k-htc firmware-atheros 

it works ok in either usb3 (blue) and usb2 (black) ports.

If your sources are the proper ones (Devuan), the firmware installed should be without any issues.

... how that happened.

Maybe you purchased a counterfit Techno N150?
Your description of the packaging would seem (?) to point in that direction.

That said, a USB wi-fi adaptor with 'N150' in the label could be one of a great many brands using that Atheros chipset in different physical formats.

eg:
https://tehnoetic.com/tehnoetic-wireles … earch=N150
https://tehnoetic.com/tet-n150hga?search=N150

You may want to contact Tehnoetic to ask if what you purchased is genuine.
ie: send photos of the hardware, the packaging and a *.txt file with the terminal printout when you run:

~$ lsusb

Best,

A.

@Altoid  I didnt questioned if the dongle comes from TE . But whether it would work ok in my system.

Anyway i checked more carefully the enclosure:
It has one the one side a TechnoEthical sticker and on the other side :
N1 4939 DNUA-93F
