[SOLVED] RT5572 Wireless Adapter does not work on my Rock64

[Christian_]

Hello.

 

Please could someone help me to solve this issue?

I have a wifi dongle recognized as: Bus 002 Device 002: ID 148f:5572 Ralink Technology, Corp. RT5572 Wireless Adapter

I am trying to use it on my Rock64 and ARMBIAN 5.42 testing Debian GNU/Linux 9 (stretch) 4.4.124-rk3328

uname -a:
Linux rock64 4.4.124-rk3328 #24 SMP Wed Mar 28 17:15:52 CEST 2018 aarch64 GNU/Linux

 

It seems it is recognized correctly:

lsmod:

rt2x00lib              49152  3 rt2x00usb,rt2800lib,rt2800usb

 

dmesg:

Using Network Manager had no luck, the device was always listed as disconnected.

 

So I tried to configure it manually in /etc/network/interfaces, adding this entry:

auto wlx441ca87f7a19
        iface wlx441ca87f7a19 inet dhcp
        wpa-ssid mySSID
        wpa-psk [key removed]

Still no luck, this is the log of networking service:

I also tried to add:

options rt2800usb nohwcrypt=y

in /etc/modprobe.d/rt2800usb.conf, as I read somewhere and removed and reloaded the modules, no change

 

Trying the scan manually I get no results:

wlx441ca87f7a19  IEEE 802.11abgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off

sudo iwlist wlx441ca87f7a19 scan
wlx441ca87f7a19  No scan results

 

I also connected the module to my laptop (running Ubuntu 17.10) to be sure it works, and from there I can connect to my wifi just fine (using Network Manager).

I also can connect to wifi using another usb adapter (Realtek 8188EU USB) on Rock64 with Network Manager.

 

Any idea?

Thanks in advance.

Blacklist in-kernel driver and search around for more recent known to work drivers (sources), install headers and compile the module. Repeat until you find a working one. When you find a good working one, we can once replace them with those shipped with the kernel. Ideally: send a patch against kernel source.

The problem was the wifi region setting unset, this prevented to tune the radio to channel 1.
