Are you going crazy with your A6210 Netgear WiFi USB Adapter on Linux?
I guess you will find the solution here!
First of all, get and compile the driver module from here (follow the readme instructions):
https://github.com/kaduke/Netgear-A6210
It should work just out of the box after the installation of this driver, but, if you got a similar error:
[ 4.523632] mt76x2u 2-1:1.0: Direct firmware load for mediatek/mt7662u_rom_patch.bin failed with error -2 [ 5.278780] mt76x2u: probe of 2-1:1.0 failed with error -2 [ 5.279262] usbcore: registered new interface driver mt76x2u
You will have to download the mt7662* driver from here:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek
and then put the module in the right place:
# mkdir /lib/firmware/mediatek # cp mt7662* /lib/firmware/mediatek/
Unplug and plug it again the adapter and now should works fine!
I’ve tested it with a Raspberry 4 with raspian buster
Linux raspberrypi 4.19.93-v7l+ #1290 SMP Fri Jan 10 16:45:11 GMT 2020 armv7l GNU/Linux
If you have any issue on Raspberry 3, please take a look here
https://github.com/jurobystricky/Netgear-A6210/issues/57
and edit file /boot/cmdline.txt and add coherent_pool=4M to the end of the file.
That’s it!
