how to enable wifi on TX1?

I got this TX1 board from former employee. It’s running fine with Ubuntu 16.04. I found one strange thing that I couldn’t configure WIFI.

nvidia@tegra-ubuntu:~/Downloads$ sudo ./

Checking MAC address configuration
MAC address configuration is correct.
Checking WiFi settings next

Test inconclusive (WiFi settings unknown). Please make sure WiFi is enabled under network settings, reboot the system and re-run this test. If you encounter this error again, visit the product support page at

Does anyone know how to enable WIFI?



Hi scheng,

Do you flash it with Jetpack3.1 BSP? If you are not sure, could you try it first?

Does wlan0 interface show?

Yes, I flashed it two days ago. I don’t see wlan0 interface at all. Is there any hardware button/jumper or software flag to enable it?

Could you paste the kernel log as an attachment?

I am curious if this command works (I’m testing if sudo works…if prompted for password it probably works):

sudo ls

If that works, see if all is “ok” in:

sha1sum -c /etc/nv_tegra_release

I’m just thinking to make sure the NVIDIA-specific drivers are in place with proper permissions (WiFi requires sudo in places).

You may also post the output of :

rfkill list wifi
service network-manager status

Your ethernet adapter is named ‘enx00044b635324’, are you running standard L4T ?
On Jetson dev board it should be eth0… Are you using a different board or ethernet card ?

[EDIT: you may check this for similar symptoms: Are you running a custom board, a modified device tree?]

for comment #5,

  1. yes, sudo works for sure. I got most stuff like opencv/cudnn/yolo/slam works.

You may get more info from:

cat /var/log/syslog |egrep -i "wifi|80211|wlan|bcm|dhd|Dongle Host"

Syslog has many details, but may have traces from previous runs. You may also generate the kernel log since last boot with

dmesg > kmesg.log

and attach file kmesg.log (you can only attach a file to previously sent post).

Furthermore, it may help to give your L4T version and tell if it is a standard or custom board, and if it is running a modified device tree/kernel/drivers/firmware.

looks like I don’t have bcmdhd.ko at all…

dmesg.log (71.6 KB)

Sorry, using syslog was not a good idea…Seems syslog has just been rotated and you got a fresh syslog file. Using the same egrep command on dmesg output would have been more relevant.

Anyway, looking at your demsg.log, it seems it doesn’t activates DHD. On my TX1 R28.1, I get these lines missing in your case:

Would you suggest how to fix it? thanks!

Hi Steve,

I was mainly helping to make the diagnosis, not sure I am a good therapist for this.
I have to say that I’m not using wifi on my TX2. Maybe there is enough information for someone else to figure it out.

For fixing this, I would consider that even fixing wifi may leave some other things broken, as I have no idea what your collegue has done with it, so the easiest way would be to download fresh JetPack and reflash. Updating packages after the new install, the whole process would take about an hour from now to get a full capabilities system running. If not, you may consider RMA if a hardware failure persists.

Of course, this depends on what work has been done on the Jetson, if it can easily be saved and reinstalled later…

It looks like a hardware issue here since reinstall also not work and dmesg shows DHD is gone.
I would suggest a RMA process here…
