So... I made a sin. Or a lot of them. I took a Raspberry Pi with me for a trip for toying a bit, and installed Rasbian with the full desktop.
I was watching a video and it installed this and I needed to also install OMV because it depended on it to work. The thing is that it killed my WiFi. After a while I could connect to the network (I can SSH into it, and the OMV webpage is up), but it has no WiFi!!.
When I hover over the WiFi panel, it says "Connection to dhcpcd lost". I checked and /etc/dhcpcd.conf was gone. I restored it. Next, I went to /etc/network/interfaces and even tho I so a comment saying it was an aout-generated file by OMV, it was identical to the original one.
What am I missing? I'm in the network and I can ping other people and access the Pi from other devices, but it doesn't show it in the panel and I don't have internet. I won't have access to a different SD for at least a week so I'd be nice solve this before.
Thanks a lot!
Also, if someone from the future comes here for reference on how OMV killed your WiFi for doing stupid things like me, so far I got it working (without internet) with:
sudo ip link set wlan0 u
ifconfig #it now shows the wlan0 interface
#rebooted and configured the localization for WiFi
raspi-config
#edited the wpa_suplicant and added my network (it was done in my case because I already had connected to the WiFi before, but you could look up for a guide on how to connect to WiFi from terminal)
