Hi Bela,

Forgot to tell you, /home/tc/.ash_history  file gets corrupted on the last  few releases.
Use the up arrow more than a few times after reboot to replay last commands, rubbish pops up.

Still have the issue with the external wifi and RPi3. It works only short time and than disconnect.
In dmesg:
Code: (bash) [Select]
[  173.520788] usb 1-1.3.2: USB disconnect, device number 6
[  173.521133] rtw_cmd_thread: DriverStopped(0) SurpriseRemoved(1) break at line 482
[  173.829830] usb 1-1.3.2: new high-speed USB device number 8 using dwc_otg
[  173.931204] usb 1-1.3.2: New USB device found, idVendor=0bda, idProduct=8176
[  173.931222] usb 1-1.3.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[  173.931236] usb 1-1.3.2: Product: 802.11n WLAN Adapter
[  173.931248] usb 1-1.3.2: Manufacturer: Realtek
[  173.931261] usb 1-1.3.2: SerialNumber: 00e04c000001

But it is not exactly disconnected. Guess there is some issue with the USB driver.

Got it!
The issue was caused by the interference from the RPi3 board, probably Bluetooth / WiFi transmitter.
When placed the USB hub far away from the RPi3 board, it works well.

Hi Steen,
that was the first, what I've done, but there is no similar command for the WiFi too.
Hope, it will come soon hence the overlay structure and quantity increased a lot now with the RPi3 board.
I'm looking for the new piCore release based on the new kernel to have ability to use the new overlays.

Did you try rfkill to disable WiFi?

it doesn't work, hence it is not yet mapped as the wlan device.
I'm not loading the firmware files, and guessed that it will not start to work, but even than it somehow works and the transmitting radiates the noise. Supposed that there may be some low level "hardware" switch similar to pi3-disable-bt to safely keep it really OFF.

Not working at all. It's still only "soft switch" working only after boot time. During boot it still generates noise and causes flickering of the TFT screen.
Will wait for the new firmware and kernel update to have "hard switch" as is for Bluetooth.

How do you know if Bluetooth and WiFi transmitters are enabled ? dmesg doesn't show BCM43438.

Because of radiated interference. Don't know if it is Bluetooth, or WiFi, but it radiates noise.
