There is a problem with the network connection

my computer is connected to the company"s wireless, and the Internet speed is very slow (basically equal to no Internet. (but there is no problem with my computer connecting to the wireless at home.
I have no problem with my mobile phone even if I am wireless in the company.
turn on the hotspot of the mobile phone to connect to the computer, and the speed of the computer network is fine.
excuse me, what is the reason for this?
