Connecting to wifi

I have updated my software on the phone. I can connect to the wifi at my home. At work, everyone else can connect to our company wifi but me. I have done the Reset Network Settings a hand full now. I have powered phone off so many times. It will try to connect but never will since this past Monday. Router is fine no one else is having issues. I have select to forget this device so many times as well. Still not connecting. This has to be a phone issue since everyone is running fine. Please help.
