AR300M: log is flooded with info messages, when wifi off

Barney · 2019-05-19T13:18:46.830Z

I installed firmware file openwrt-ar300m-3.022-0329.tar on my AR300M.

When wifi is off, the logs are flooded with info messages. About every 20 seconds the following lines appear in the logs:

When I set wifi on, the log entries do no appear (see above at 14:52:06). I do not use any ipv6 addresses in my home lan, so every ipv6 related configuration value is untouched (factory default values).

How can I stop the above log entries in the mode “wifi off”.

Can you turn off repeater manager?

@ alzhao: Thanks for your reply.

Where can I turn off the repeater manager? Are you talking of the menue INTERNET → Repeater → Repeater Options? After clicking on Repeater Options I get a box with the two options:

Auto detect Captive Portal (OFF)
Auto scan and re-connect (ON)

I switched “Auto scan and re-connect” from ON to OFF. Does that mean “turning off the repeater manager”? Is it enough to reboot or shall I power off and on the device?

you are doing it right.

No need to reboot etc. It take effect immediately. But you can reboot to clear your log.

That did the trick … at least partially. The flooding stopped as long as I do not open any of the UI (GL or luci). When I login in one of the UI and modify any option, the flooding starts again until I logout.

Any chance to completely stop the flooding?

When you log in the UI, it tries to get info from the router continuously. As your WiFi is off and it has to create some temp interfaces etc so that it can get data. So you will have more log.

Just turn on the WiFi or don’t let the UI open all the time.

Your explanation makes sense … at first sight. I’m still wondering, why these messages only appear for ipv6 and not for ipv4.

Nevertheless, thanks for taking time, reading and answering my posts.
