Internet connections at work won't work!

Hello,

My Debian 9.1 stretch connects flawlessly, both through ethernet and wi-fi everywhere BUT at my work. I'm guessing they are using a particular set-up, but can't work it out.
I have three options available :
a) Wifi
b) Ethernet port in my wall
c) Ethernet port in my phone.

Options a) and c) works from windows (option b) does not, oddly enough)

a) Wifi

When I try to connect to the wifi (let's call is SSID), I'm prompted with

Password dialog - Kde daemon
For accessing the wireless network 'SSID' you need to provide a password below
I enter my password, wait a bit, and am prompted with the same dialog box. After some back and forth, a dialog box pops up with

Wireless Interface (wlp2s0)
No secrets were provided
and
SSID
Connection 'SSID' deactivated

The phone is a Cisco phone (VLAN) -- UC Phone CP-7841, there is an ethernet port on it.
The computer connects flawlessly, but can't access anything:

Hi @aaa and a hearty Welcome to linux.org.

A fair bit of this may be beyond my pay grade, but I guess a couple of obvious questions for others to assist might include:

  1. Are you allowed to access your work's internet? and
  2. What medium are you using with your Stretch in terms of its housing unit - is it a laptop, a tablet, a phone?
Cheers and good luck

Thanks for your kind words.
It looks indeed like the restriction came from the (really odd) way the access to Internet was restricted at my work.

Thanks for the insight and the welcoming words.

Is work a windows environment? They might be doing domain authentication and since your linux is not part of the domain it isn't allowed to use the internet.
