Maybe the WiFi 2.4GHz in out on channels beyond 11. Did you change your region in your phone and laptop so you can see to channel 14?
Also, you need to let the IT work this as they could have MAC address filtering or some other security.
So, I am on a US factory where all of the devices are connected on a general wifi network. I should say that this wifi network is not a common network for internet purpose. Any person can view all of the networks easily, just by searching them on their smartphone or computer. Although that configuration, the network is very safe and secure.
Otherwise, the problem is with me. The wifi networks does not appear in my devices, neither smartphone neither my computer. And I tried by searching the networks right next to a random person (not a worker, in case you think the IP of them is granted), and yes, the networks are shown in his devices.
I should add (which I think it could be the reason) US is not the country where I live, I just came here some days ago for working purpose. I thought maybe it could be some international configuration thing, but I have no idea where to look over.
Thank you, and sorry for the long text. I hope that is clear
