Interface does not setup on startup

[Pablo Álvarez Córdoba <pabloalvarezcordoba@protonmail.ch>]

Hi folks.

I have Debian 9. I configured my wlan interface to auto connect on startup.

But, networking service does not startup:

● networking.service - Raise network interfaces

   Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor preset: enabled)

   Active: failed (Result: exit-code) since Wed 2018-09-12 08:05:55 CEST; 33min ago

My net card is:

02:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)

        Subsystem: Lenovo QCA9377 802.11ac Wireless Network Adapter

        Kernel driver in use: ath10k_pci

        Kernel modules: ath10k_pci

-------------------------------------

My /etc/network/interfaces looks like:

auto wlp2s0

iface wlp2s0 inet static

        address 192.168.15.138

        netmask 255.255.255.0

        gateway 192.168.15.1

        wpa-ssid MY_SSID

        wpa-psk MY_PASSWORD

If I run journalctl, I can see:

kernel: ath10k_pci 0000:02:00.0 wlp2s0: renamed from wlan0

This is after execution of networking.The problem is that interface is renamed after networking uses its name. How could I solve this? (no, I will not put wlan0 in my /etc/networking/interfaces, this is not the correct solution)

Thanks.
