Hi Vijay ,

firmware recoveries do happen and it takes less than 1 sec for system to recover in most cases. In your case driver initiated a recovery due to tx issue . It's important that system recovers ok after firmware recovery .

Hi,

What to look now further so that we can fix the issue. After recovery system comes without any issue then it will be fine but in our case system is not come out of the issue. Please suggest further to solve the issue.

Vijay

Hi,

The issue comes randomly so it is hard to know pre & postcondition. After recovery, I don't see SSID visible.

I think best part from the given log get clue to where we can look more. Let me know if anything else I can test.

Regards,

Vijay

Vijay ,

above log does not give us much info . can you elaborate on"I don't see SSID visible" ? is wl8 running AP role ? if yes, how many stations are connected to it ? can you share output of 'ifconfig' before and after the issue

Thanks

Saurabh
