Jetson TX1 WiFi issues

I’ve been having issues connecting to the WiFi using two of my Jetson TX1 boards that I recently upgraded to Jetpack 3.1

When I try to connect to WiFi using

sudo nmcli dev wifi con "WIFI_SSID" password "WIFI_PASSWORD"

On two different WiFi-APs (both from TP-Link) I am getting two different behaviours.

On AP #1, I get

Error: No network with SSID 'WIFI_SSID' found.

This is strange as all the other computers and phones, including some other Jetson boards which are also on my desk are happily connected to that same SSID. I tried

sudo nmcli dev wifi list

and I see ALL other SSIDs in the area except this specific AP.

On AP #2, I get

Error: Connection activation failed: (7) Secrets were required, but not provided.

I looked at dmesg output and it shows…

Does anyone know what this error means?

[ 2413.533541] CFG80211-ERROR) wl_is_linkdown : Link down Reason : WLC_E_DISASSOC_IND

I’ve already tried using wifi-config-check.sh and it showed no error.

HI notthetup,

Are both devices tegra devkit?

I will try nm on my devkit today as well. Please wait for my result.

Thanks for patience.

Thanks Wayne.

Not sure what you mean by tegra devkit. They’re both Jetson TX1 boards. How can I check this?

-Chinmay

Never mind, just wanted to make sure you are using a tegra devkit instead of a custom carrier board.

-Wayne

Yes. I’m not using custom carrier boards. They’re both NVIDIA Jetson TX1 Development Kits.

Hi notthetup,

We try to connect six different Wi-Fi ap are no issue.
Please check your wifi router (your settings or restart it).

Thanks!

Do you know what channel the missing SSID is broadcasting on? The TX-1 and your router may not support the same 5Ghz bands.

Thanks @carolyuu.

Good point @sperok. I’ll check the channels of my router later today.

Hi notthetup,

Have you resolved this problem?
Any good result?

Thanks

Thanks for reminding me about this @kayccc.

I restarted my router a couple of times and the issues went away. Strangely enough.
