I've tried to use all type of external antenna's (2.4GHz & 5GHz) for transmitting Miracast, but the signal was very bad.
As a matter a fact I do need help, we are going to base our product on this feature (we are selling thousands of units per year). Please let me describe the issue I am facing: I when using the Miracast feature by projecting from any PC to the product I built (with the 3168 Wi-Fi module), I am not getting a clean picture.
I am using the following setup:
intel module 3168NGW installed on the Asus motherboard H310Twith two external antennas (5dBi 24GHz/5Ghz).
I think it's better if can show you by skype or any other tool.
Appreciate your help, but to be honest I still have the problem and I don't feel that I received the right answers. I seriously think to replace the intel module. No one is giving answers that can solved the problems.
