Raspberry 3 with USB Wifi Stick

fritz_hh · November 30, 2017 at 2:14 PM

Hello everybody,

i have a little problem with my LibreELEC / Tvheadend client.

The onboard wifi modul on the Rpi 3 is not fast enught to see HD TV.

So if ordered this WIFI USB Stick: ANEWKODI Wlan Stick 600Mbit/s, 5dBi Antenna, Dualband: Amazon.de: Elektronik

In the Rpi3 'confi.txt' i have diabled the onboard modul with entry:

dtoverlay=pi3-disable-wifi

When i plug the USB Stick on the Rpi 3, LibreELEC identify the Stick in lsusb as

Bus 001 Device 004: ID 0bda:a811 Realtek Semiconductor Corp.

When i connect the Wifi Network on the Kodi Frotend, LibreELEC give the folowing Error Message:

Network Error: Did not receive a reply. Possible causes include: the remote App

The Stick connect the Network with really good performance but i can't find any entrys at the logs.

When i connect on the ssh console with connman he give no Error Message and connect.

But the problem is when i give the Rpi a reboot from the kodi frontend or with ssh,

in both things LibreELEC lost/forgett the Wifi Settings and the Key.

So i must re-enter the Settings an the key at each reboot

The connection manager stores network profiles via hardware MAC address, and your device is probably configured with 00:00:00:00 so each time you reboot the kernel assigns a new random MAC. This does not match any existing stored profiles, so you need to configure the network (again).

"dmesg | paste" and share the URL generated to confirm.

Hey chewitt,

here i have a print out of dmeseg it's from my test with OSMC but is have the same problem.

I think it is the driver for the rtl8812au chipset he can not read the MAC from the EPROM...

I had the same problem in the past. My libreelec setup was only able to see the 5ghz channel 36 and 40. So maybe if you set the 5ghz channel in your router to 36 or 40 the problem is solved.

fritz_hh · December 2, 2017 at 12:09 PM

That's interesting too but i can see all Networks in the neighborhood 2,4 an 5 ghz.

But in case the system can not rigster the real MAC Adress from the Chip that is realy strange that wil work with your solution....

Crazy

But maybe there are a other or newer driver / frimware for the Chipset that i can install or modify?

Manufacturers can save $$ if they do not acquire a block of MAC addresses that require each chipset to be programmed with a unique identifier. Finding devices with ^ no MAC is an increasing trend among cheap USB wireless devices.

It's possible to force a specific MAC using udev rules but it's better done via kernel boot params as these are effected when the driver module loads at boot time. Right now I've forgotten how to do it .. I'll need to Google.

fritz_hh · December 3, 2017 at 9:09 PM

Thank you chewitt,

now i have write a driver option file in /etc/modprobe.d/8812au.conf

Code

options 8812au rtw_initmac="6b:XX:XX:XX:XX"

but now i can't find the wifi chanels 12/13 on 2,4 ghz and no 5 ghz Networks

When i remove yet the conf file and reboot the usb wifi will also not find networks on chancel 12/13 on 2,4 ghz band and 5ghz anymore.

**chewitt** · December 4, 2017 at 5:20 AM Official Post

Code

echo "options cfg80211 ieee80211_regdom=DE” > /storage/.config/modprobe.d/cfg80211.conf

^ Do that to set the wireless regulatory domain. It should allow channels 12-13 if allowed in Germany. If not, you have to break the law and set the regulatory domain to somewhere that allows them.

fritz_hh · December 9, 2017 at 3:05 PM

Thank You chewitt,

that's works fine

On LibreElec 8.x, OSMC 2017-10-1, openElex 6.x

Here are the soloution compared for all that have se same problem with a externl Wifi device that have no MAC adress.

For Rpi 3 diable the Internal Wifi Module is it necessary to edit the config.txt file:

Code

mount -o remount,rw /flash
nano /flash/config.txt

Add at the End: dtoverlay=pi3-disable-wifi

Code: config.txt

...
dtoverlay=pi3-disable-wifi

and Save after a reboot the internal Wifi Module is diabled.

For the external Wifi Module based on "rtl8812au" Chipset without a MAC Adress:

1. Give the System the local info for the Wifi add the File "cfg80211.conf" in the directory "modprobe.d"

LibreElec/openELEC: /storage/.config/modprobe.d/

OSMC: /etc/modprobe.d/

Code: cfg80211.conf

options cfg80211 ieee80211_regdom=DE

2. Set a fix MAC Adress for the device

Code: 8812au.conf

 options 8812au rtw_initmac=xx:xx:xx:xx:xx:xx rtw_ht_enable=1 rtw_cbw40_enable=3

Now reboot and enjoy
