Asus laptop wont connect to certain network anymore

Hi !! .. Okay, so I got myself a new asus laptop about 2 weeks ago. I brought it to work and connected it to my works wifi , as I always do with my phone as well , and everything worked perfectly. I was able to use the wifi for about 3 or 4 days when suddenly the next day it just wouldn't connect anymore. So I tried forgetting the network and reconnecting, but it says "verifying and connecting" and then "cant connect to this network" .. The password definitely hasn't changed, I can still connect to the works wifi with my phone and other devices, even when I forget the network and reconnect. And my laptop can also connect to other networks and hotspots, like my phone, my moms phone, the cafe's network, etc. So the laptops wifi does work, just not with the works network anymore.. If anyone has any suggestions or thoughts please ?? I would really appreciate it.And im not very tech clever, so please explain nicely so I know what your talking about :) ! Thank you.
