Hmm, from what I can tell from the stacktrace it has either an issue to start the wireless driver in flint or it has an issue to boot the driver.

Could I ask a few questions:

  1. what where your last changes before this happened?

  2. what firmware is being used?

  3. did you flash something else than the stock firmware or by the use of a programmer? or did you do a chip replacement with a different size? (From researching it seems the wifi driver can disappear when you flash a different size on a different chip).

  1. Has the ssid valid symbols in the config or do they invalidate, could you test?

  2. I just googled did you do anything related to the country code ?, It might be crashing by this.

I guess it could be that its fixed when you update to a newer version or do full reset?

3

We’ve checked the information. It needs some time.

thanks @lizh

More info:
Using latest firmware as of now, 3.2.0.8.

Everything out of the box, nothing customize, SSID looks good, the router is pretty solid at 3.2.0.7 version.

Maybe just a random crash, but will like to know what is the issue, thanks.

@lizh crash again today, more logs here:

You can test it with V3.209.GL.iNet download center

The above problems are caused by USB ports.

Just upgrade firmware V.3.209 and found out that it will initial the setting to factory default even when you’ve checked the option “keep settings” from UI. :face_with_raised_eyebrow:

Thanks for your feedback, I am doing a lot of stack testing to verify this problem.

It is a bug that happens sometimes. Wait for a fix.

Hi, Jounouchi, the new testing firmware qsdk-ax1800-3.214-0413.img is released to address the crash issue, could you please have a try.
