Good morning, i have a problem with a range extender, the model that is written above. I have configured it following the instructions and, when I use mobile phones wi-fi goes perfectly. The problem arrives when I try to connect the ps4 to the extender, via wi-fi and so via ethernet cable when I verify the internet connection it is activated but when it appears the download and upload speed it says I have only a few kbps and the game "lags". I have an optical fiber that goes to 100mbps so with ethernet cable I should have 80mbps fpr minimum. I have the same values with the pc, please help me to understand what is wrong and what can I do or I will have to send it back. Thank you for the answer, have a nice day.Martina
