Question for USB 3.0

Hi, 

Thanks for your time reading this. 

Going to keep it simple to avoid any confusion. I was using my mobile phone 5G internet(unlimited data) for my internet at home whilst new internet lines are installed in the local area. 

I added an m2 SSD to my ASUS PRO GAMER 97 motherboard and it has superceeded the bandwith to my wifi network adapter in the PCI express slots. - This is understandable i do not need help with this otherwise i would go and search ASUS support. 

What I need to understand is why my network adapter had no issue connecting to my mobile hotspot but the a7000 wifi adapter will not discover the connection, it finds all the local wifi but not the mobile hotspot. 

Is there a reason for this? Is it unable to connect to it? Am i missing why it shouldnt be able to? Is anyone able to explain a successful connection with their own mobile hotspot? 

Thanks for reading and i appreciate your time.
