Some small number of developer kits have a manufacturing problem that can impact WiFi.
Please go to https://developer.nvidia.com/embedded/support to download and run the wifi-config-check tool to find out whether you need to request a replacement developer kit via the RMA Process. Use the wifi-config-check tool to determine for sure, but signs of the affected behavior include:
clicking on the desktop Network Manager, shows WiFi “device not ready”.
scanning for WiFi networks will result in failure:
$ sudo iw dev wlan0 scan
command failed: Network is down (-100)
Thanks to those in the community for reporting earlier on their condition and S/N’s. We reached out to these individuals previously to get their process started. For others receiving factory units, please run the wifi-config-check tool to deem if your unit needs replaced. At this time we are doing advance replacement with shipments including return postage for the affected unit.
Mine came in the other day. Wireless is flawless now. Excellent support and quick turnaround on this issue. Now if you guys would just give us a cuda lib we can run on our chrooted 64 bit file systems all would be golden. I used the instructions here to set mine up Debootstrap - Debian Wiki. It rocks in full 64 bit mode. An ARM64 cuda lib would be such a nice Christmas present :)
Advance replacement would be nice. I hope this is still the case, because I have one.
Also, your script writers might want to note that not everyone keeps the “ubuntu” username, Hard coding that assumption into the script seems a bit… well… insert your word of choice :)
Out of the box my wifi was working fine. But wasn’t sure if there could be a problem deeper that I wasn’t aware of. So I tried downloading the wifi config tool from the Tx1 and everytime I did it with firefox (the version that comes on the board) it crashed the browser. Had to download from another computer and get it across my network. I guess I could have done it with a thumb drive as well seeing I have a USB hub connected. Anyway then I couldn’t get it to run no matter what I did until I set permissions on the file. So…
sudo chmod u+x ~/wifi-config.check.sh
sudo ./wifi-config-check.sh
The i2c-tools package is required
Download i2c-tools via apt-get [y/n]: (type Y for yes and hit enter. The following below is automated)
Running Apt-get update
Running apt-get install i2c tools
Checking MAC address configuration
Configuration error found. Correcting…
Please do not interrupt, or system data corruption can occur
Fixing naming of Wlan interface
Error corrected. The correct Mac address will be effective after reboot
Checking wifi settings next
=================================
Your developer kit is functioning correctly.
Please chec file: /home/ubuntu/wifi-config-check-log for more details
ubuntu@tegra ubuntu:~$
Then reboot/restart
You should still be plugged into ethernet so check ethernet connection: it should still be good. Unplug ethernet, activate your wifi network from the upper right hand corner drop down of the desktop. Login into your wifi network and test wifi connectivity. After all that you’re ready to rock.
So I tried downloading the wifi config tool from the Tx1 and everytime I did it with firefox (the version that comes on the board) it crashed the browser.
Not the most convenient workaround, but most of the time I have luck copying/pasting a download link and grabbing it with the “wget” command if the browser is acting up.
I am experiencing the wi-fi problem on TX1 S/N: 0320716034412
“Device Not Ready” and “mmc1:Data CRC error”
A couple of other notes:
My wired ethernet connection would not work either until I ran: sudo mv /lib/firmware/brcm /lib/firmware/brcm_ and rebooted.
My Ethernet wire connection was working OK until I ran steps 1 thru 7 of the TX1 install instruction for OpenPTrack: Jetson TX1 Installation · OpenPTrack/open_ptrack Wiki · GitHub This could be due to the MaxPerformance tweaks just manifesting the wifi issue.
If it says you have the issue, please request RMA following the procedure from here: [url]https://developer.nvidia.com/embedded/support[/url] In the event of RMA, they should send you a replacement unit in advance.
If you think the issue you’re experiencing may be related to item #2 from your post, you can try re-flashing your Jetson with the latest JetPack.
Unreal! I just got the replacement TX1 I requested by RMA and it has the same problem!
From the wifi-config-check-log:
This generated file provides details if the Jetson-TX1 is configured properly for Wireless connections or not
Serial Number of Module is 0322016080106
Serial Number for Base board is 0322116018045
A manufacturing problem has been detected. This may impact performance and stability of your developer kit. Please go to https://developer.nvidia.com/embedded/support to request a replacement. We are sorry for the inconvenience.
This is not good. Is it really just a “few” units affected?
After flashing my Jetson TX1 board with Jetpack 2.3.1, I am unable to detect or connect to Wifi or use the device as a wireless access point: [url]https://devtalk.nvidia.com/default/topic/910608/jetson-tx1/setting-up-wifi-access-point-on-tx1/[/url]. Flashing the board with Jetpack 2.3.1 was the first thing I did so I am unsure if there was functionality beforehand. I am able to access the internet via ethernet, but I am hoping to have this board host its own access point for use in my projects.

MAC address configuration is correct.

This returns nothing and no wireless signals are detected in network manager…

Interesting, I thought I had a different link, but it is just the same as you already have. Sorry, my notes are apparently are missing a specific reply I was looking at.
I currently have a similar problem to dbourque3. I can access the internet over an ethernet cable, but I need it to work with WiFi. The board is flashed with JetPack L4T 3.0 (OS-version 24.2.1). Here are some outputs:
ubuntu@tegra-ubuntu ~/boardconfig % sudo ./wifi-config-check.sh :(

But when running a scan, the board can’t find any WiFi:
