Phone doesn't require security key for wifi, but tablet does?

[BoJangle]

Hi, I've recently been using a wifi network at work with my Galaxy S5, requiring no security key to connect. Ive recently brought my Microsoft Surface Pro 4, running Windows 10, and it wants me to enter a security key to connect to the same network (that my phone is connected to at the same time)
Any thoughts?

Edit: Unsure whether we're even supposed to use it, but it's the strongest signal (the others are pretty much useless)where I'm at, so don't wanna contact IT.

Ask your network dudes at work?

It may be the rules that they have defined, using the managed network interface. If you don't know whether you should use the network then
DON'T use it
