Hi,

The dump now after runing the wpa_supplicant command is as follows:

l2_packet_receive - recvfrom: Network is down
l2_packet_receive - recvfrom: Network is down

I have not selected the L2 packe receive in hostapd and wpa, would that be an issue. Key and authentication process is WPA-PSK at both ends.

Thanks
