how to put the d-link DIR-615 E3 into repeater mode
I need your help in the following. I have a D-link DIR-615 E3 see 5.13, which I would like the following:
1) I want to place it as a repeater to expand my Wifi signal in the warehouse.
2) How can I take it to the Spanish language.
I have seen some videos on the Internet and I see that they have it in Spanish. I already updated the firmware thinking I could do it but it is still in English. part that in the videos that I have observed where they teach how to place it repetitively and are not the same minutes despite the same D-Link model. Thank you very much for your help.
