Qubes 3.2: No Internet Connection, neither with Wi-Fi, neither with Ethernet.

[ghost]

Qubes OS version (e.g., R3.2):

THIS CONCERNS QUBES 3.2 (latest update, downloaded from the website 3
days ago).

Affected TemplateVMs (e.g., fedora-23, if applicable):

sys-net

---

Expected behavior:

1-Once the ethernet cable is plugged in the proper ethernet port of the computer, it should display "Connection Established" with a notification in top right corner;
2-Once the Wi-fi is "Connected", I should be able to ping google.com with the command "ping google.com -c 5" inside the sys-net terminal.

Actual behavior:

1-Once the ethernet cable is plugged in, absolutely nothing happens. And on system boot, once the desktop is loading (and if Wi-Fi is disconnected), the notification "Disconnected - the network connection has been disconnected" appears in the top right corner.
2-Once the wi-fi connection is established (without any problems at all), it simply doesn't work, like if it was disconnected. In fact when I go to sys-net terminal and execute the command "ping google.com -c 5" it waits a few seconds before displaying "ping: unknown host google.com".

Steps to reproduce the behavior:

Simple Installation of the OS, choosing only first 2 options during last Qubes configuration (sys-whonix not installed, and neither torification for updates)

General notes:

WHAT YOU SHOULD KNOW, AND WHAT I HAVE TRIED:
1-The ethernet cable, Wi-Fi card, Ethernet card, of the computer are all perfectly working;
2-Both Ethernet and Wi-fi cards are attached to sys-net VM, under 'devices' as it should be;
3-Both the Wi-Fi card and the Ethernet card are recognized by Qubes, in fact, heres the output of 2 known commands:

"ifconfig" output below. NOTE: I MODIFIED the inet6 address, and the ethernet addresses from "Vif2.0" and "wlp0s1" respectively, I would prefer to keep them private. :

4-This problem has been present since the first installation, occured 3 days ago, in the meanwhile I tried to fix it asking on reddit/r/qubes/ and on whonix forum;
5-From the same usb containing Qubes installation, I have installed qubes in another computer of mine(laptop), and on it I did not have such problems (and I used the same ethernet cable).
6-I'm not sure this is as it should be or not: during installation (which I have repeated in the last 3 days literally 8-9 times across different pcs.), at any point, I came across a Network setup configuration like in every other operating system I have ever used (linuxes and windows), and a guy on reddit told me he went through something like that.
7-NOT a very important point, you can skeep this one if you want.
I noticed that during boot on my laptop pc (the one where internet works perfectly) when it asks for the passphrase, it loads a proper window, with background and box to type in the passphrase. In my desktop computer instead (the one with the internet problem), this does not occur, I have to type the passphrase directly in the boot. All of this made me think that Qubes installation is everytime overfitted for the current hardware.

TELL ME WHAT YOU NEED TO SEE AND I'LL POST.

PLEASE HELP ME FIX THIS, QUBES WITHOUT INTERNET IS POINTLESS, and you'll help me get rid of this powerful headache I have right now.
