Wireless hotspot random failure right after boot

Hi,

I own multiple TX2s flashed using Jetpack 3.2.1.
I am currently using hostapd 2.6 to create a WPA2 AP on the 5GHz band.
Everything works well, hostapd is set to be launched as a post-up script on the wlan0 interface.

When the tx2 boots, the generated hotspot is visible 100% of the time. However, after around 5% of boots, it is not possible to associate with the hotspot (tried from a linux and windows computer), when this happens the wireless network on the client PC switches back to “disconnected” after a 10 second delay. The WPA2 password is correct and stored in the network manager’s cache.

I have compared the dmesg output between a “successfull boot” and a “bad boot”, and the only difference is I can see some deauth information after the “bad boot” sequence:

and so on.

hostapd is always launched with the same parameters, the hotspot is always visible.
The tx2 is powered from a regulated 12V lab power supply.

When this happens, just rebooting the tx2 (power off power on) solves the issue and I am able to reconnect again normally.

Why am I getting deauthed from the driver? I have tried searching on the forums with these error codes, with little success.

Thank you very much for your help!

When the deauth happens, is restarting hostapd resolving this issue?

Thanks for your answer.
Yes, only restarting hostapd solves the issue.
Could it be that starting hostapd right after wlan0 is up is too soon in some cases?
I’m trying to get hostapd to log in verbose mode to some file, but it seems that it’s not possible when using the daemon mode of hostapd.

Ok, here is the full verbose log of hostapd when association fails:
https://pastebin.com/Pv4HjRJZ

Then i restarted hostapd, and association worked (new log file after restart: https://pastebin.com/JzYdjAyy)

It seems trouble happens around here (line 237):

Thanks for your help!

Hello, I also have a similar issue.

I have 2 TX2s running JetPack 3.1. The access point was created with NetworkManager, but to enable the Hotspot functionality, I added the following line to /etc/modprobe.d/bcmdhd.conf

options bcmdhd op_mode=2

I also disabled power-save by default by creating a file at /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf with

[connection]
wifi.powersave = 2

I am always able to start the TX2 with the AP running. But sometimes, after anywhere from 15 minutes to 7 hours later, all connected devices will be kicked and any attempts to reconnect will fail. The SSID always stays visible. Trying to connect with either Ubuntu or Windows just indicates that it is connecting with no update or password prompt until it just stops attempting to connect.

Rebooting the TX2 resets the problem, but problem has the irritating tendency of appearing when I cannot manually reboot it. There is no other network connection to the TX2s. I have noticed that this happens when I am running code that is continuously sending and receiving packets, but more than 90% of the time, this problem never occurs.

Any help is much appreciated.

Really sorry for late reply.

gotsring,
I think your issue is not same as original one. Could you file a new topic for this new synopsis?

alban.deruaz,

Actually, we don’t use hostapd as default softAP application but mainly use networkmanager.

Could you try to use NM to reproduce this issue and share the method + logs with us?
