Can't mount network drive properly over Wi-Fi

I am trying to mount a network drive on Lubuntu 16.4 Raspberry Pi edition.I want to clarify, that I can mount it using themountcommand.The issue is with mounting it on boot. I've already modified /etc/fstab.It works properly when over Ethernet.

However, when only the USB Wireless Adapter is installed the network drive fails to mount (error code -101).

I have a suspicion that this is caused by not having initialized the Wi-Fi Adapter before Lubuntu mounts the drives from fstab.

What Can I do?
