Regardless my HP laptop acted as WiFi P2P Group Owner or Group Client, during iperf testing with my phone, we observed(via wireshark) that the laptop will enter into power save mode(~100ms interval). This causes the P2P performance is very slow. This is especially strange that even there is traffic on the channel, the laptop still enter into power safe mode. We had configured the wireless adapter as: 1) no power save 2) Tx the highest power and etc.
Do you have any solution to disable power save mode? or smart enough to avoid power save mode when detecting any traffic.
Thanks for the help
