Wifi module driver issue

Autonomous Machines Jetson & Embedded Systems Jetson TX1
1

Hi,

The Tx1’s wifi module works properly after system boots and connected to my AP, I also can see all of the AP routes on the Ubuntu → system Settings → Network → Wireless.

But if try to turn off and turn on the wireless switch immediately for several times. The wireless network failure and those AP routes do not show up on the “Wirless” windows.

Here is the kernel log when I try to switch the Wireless switch. Is there any suggestions on this issue?

jjc_0115,

But if try to turn off and turn on the wireless switch immediately for several times. The wireless network failure and those AP routes do not show up on the “Wirless” windows.

What is the “wireless switch” here? Is it the GUI button on ubuntu desktop?

How frequent on/off is your usecase requiring?

Please share the version of BSP and if you can repro this issue on nvidia devkit?

Hi Wayne,

Yes, it is GUI button on Ubuntu → system Settings → Network → Wireless

within 1 second.

tegra-l4t-r28.2 with customize carries board, Our devkit of micro-USB port failure, therefore I can not reproduce this issue on nvidia devkit. Since, the wifi is build-into tx1 module, you should be get the same result on devkit.

jjc_0115,

I can reproduce your issue. We need to know what kind of usecase requires such frequently turn on/off. May I have your share?

5

That is the testing requirement from our verification team.

jjc_0115,

After some investigation, there is no fatal error in kernel log, so we guess the cause of this error is from NetworkManager UI. Could you try to remove/disable network manager and try other network manager GUI first?

7

Hi Wanyne,

I’m not sure if the root cause is related to the NetworkManager UI. Maybe the NetworkManager will re-init the wifi driver when it startups.

I tried to reload the wifi driver by following commands when the wifi failure :
$sudo rmmod bcmdhd

and the kernel log:

The issue seems to have disappeared. After updating to the newest version of network-manager via following command.

sudo apt-get --only-upgrade install network-manager
