We find that gecko issue "disconnect" and "reassociate" command to supplicant. 
Can you check whether it is ok?

Comment 8

[Wang Rong]

When can't get dhcp info once, gecko will issue "disconnect" and "reassociate", Is this necessary?

I'm confused on the STR here. Can you rephrase the STR here? I don't understand how to test this.

I believe the STR is as following:

1. Connect to some Wifi AP
2. Surf the net for a while
3. Suddenly the Wifi will disconnect from the AP
4. And it will connect to that AP again after a while.

Could we have QA to test this issue? Suggest to surf the net for at least 10 minutes.

Thanks

There is a retry count when dhcp info is not available.

Please turn on wifi debug log in settings/developer/Wi-Fi output in ADB when reproducing the problem.

Yes, I noticed that. do we must disconnect and reassociate when dhcp info is not available?
And can we get the reason why dhcp info is not available in the log?

Followed steps and surfed the net (news.google.com and maps.google.com) for 15 minutes and did not encounter any wifi disconnection.

Can't block on something we can't reproduce.
