Wifi connection and FTP

Hi,

I'm trying to use my Mi 4c as ftp server but isn't working.

Firstly I tried with the ftp option available in file explorer app without luck. Then, I installed primitive ftpd and it displays this info:

Code:

---

IP Address (Network Interface)
10.0.2.15 (usbnet0)
192.168.1.99 (wla0)

---

From my laptop, ping command can't connect with my phone:

Code:

---

ping 192.168.1.99
PING 192.168.1.99 (192.168.1.99) 56(84) bytes of data.

As you can see, my local network is 192.168.1.0/24 but my phone is not available (I don't know what is usbnet0). I tried with other apps that use a local network such as LG TV Remote or Epson iPrint and they aren't working either, What can I do? I'm using the newest rom from xiaomi.eu

Thanks in advance and sorry if my english is not good.
