@rickkas7, I am not looking for more then 800Kbytes/sec. I apologise if my last post is showing wrong impression. I am getting 2Mbps right now and looking to improve till you got in your experiments. Please suggest me how to improve it .
I agree that the Photon is great device. It has lot of features and prompt support. I like to work on photon and would like to continue for future projects / products.
@bko, I saw people use iperf to measure the bandwidth of the WiFi medium. I will try to use that and take further steps. Thanks for your suggestions.
