TX2 as wireless AP drops connections randomly

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX2
1

Hello, 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, Windows, or Android just indicates that it is connecting with no update or password prompt until the attempts time out.

Restarting the network-manager service resets the problem, but this has the irritating tendency of appearing when I cannot reboot it without a wifi connection. There is no other network device in use on 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.

gotsring,

Thanks.

I’ll try to reproduce this issue.

3

In the meantime, I’ve been unable to purposefully reproduce the issue, but it has occurred a few more times.

Other than /var/log/syslog or kern.log, are there any networking-specific logs that I can go through? I should note that I’m new to messing with drivers and system logs (even dmesg), but I’d like to at least narrow down where the issue is occurring.

4

Sometimes networking will be mentioned in “/var/log/auth.log”, e.g., if ssh is used (or if something significant is denied or allowed even if it isn’t network-related).

5

To be honest, I just checked and found we had similar issue before.

However, we failed to resolve since we are not able to reproduce this issue on our side.

You could try

1.Use “wl PM 0” to disable the power management.

  1. If above command doesn’t fix try disabling SDIO auto sleep as well
    a) Following command will work on client side
    wpa_cli -i wlan0 DRIVER AUTOSLEEP 0
    b) Host side you need add following patch
--- a/drivers/net/wireless/bcmdhd/dhd_linux.c
+++ b/drivers/net/wireless/bcmdhd/dhd_linux.c
@@ -6155,6 +6155,7 @@ dhd_preinit_ioctls(dhd_pub_t *dhd)
 #endif
        }

+       dhd_slpauto_config(dhd, 0);
        DHD_ERROR(("Firmware up: op_mode=0x%04x, MAC="MACDBG"\n",
                dhd->op_mode, MAC2STRDBG(dhd->mac.octet)));
        /* Set Country code  */
  1. Pick up the wifi firmware from rel-28.2 back to rel-28.1 and try.

Thank you for the reply. I’ll try these during the next week and get back with my results. I may just start using something else to create the access point and setting the TX2 as a client.

Update on all this.

I made a lot of changes to the code that I was running on the Jetsons, including rewriting the network sending/receiving code. This was mostly to add error handling, and ever since, I haven’t had any problems with the AP.

I’m still not convinced that the problem is gone, as sometimes a week or two passes without any issue, but with amount that I’ve been debugging with no network issues seems to indicate that perhaps something in the user code was triggering the issue. I should note that I did not yet try any of the suggestions listed above (busy making sure my end worked), which kind of adds to the conclusion that it was user code.

I’ll post updates as they occur.
