I´m creating this issue with the tough of reporting a firmeware/kernel problem, not asking for support.

Thanks a lot for your effort!

Hi, i got the same problem, but after u keep run the p2p_group_add, the network will be created successfully, I got the problem on how to set own password because it will keep generated the random password every time it created.

Can some one help, how to set the desired password for the P2P GO/AP mode.
