Are you using two AP both with ssid = “Penguinsinnovate”? Just want to make sure I understand your log correctly.

Is wifi ever connected to any one of them and able to see the IP?

Hi WayneWWW,

Only one “Penguinsinnovate” AP,this AP just restarted.
Before ap restarts, the device is always connected to this ap。

“Before ap restarts, the device is always connected to this ap。”

What did this comment meant…?? Does this indicate it works fine or …?

Hi WayneWWW,

The router disconnects the Internet, turns on wifi, the device gets the ipv6 address, and the log prints every one or two minutes.

Hi,

I think our discussion has somehow cannot have any conclusion because I cannot get what your usecase is.

Thus, few suggestion and questions for you.

  1. Please tell us what commands are you using for scanning wifi. My suggestion is please use NM gui to scan wifi manually.

  2. Please try different wifi AP and different TX1 for test. Maybe this is specific to one TX1 or AP only.

  3. Why do you mention ipv6 here?
