Macbook unable to connect to wifi

MacBook (OS X Yosemite) unable to connect to wifi at work. (I have a MacBook Pro sitting right next to it, works fine). How do I trash my wifi settings (prefs) to restore productivity?

'Diagnostics' and 'setup assistant' rejects a working password.
I have tried Disk Utility and zapping the PRAM. What am I missing here?
The network only shows as available intermittently (only on the affected MacBook). Not even my iPhone shows as available.

MacBook, OS X El Capitan (10.11.3)

What I would recommend is deleting the wifi from your system's memory. I've had a similar problem before and this helped me. All you have to do is go into settings click on network and go where it says "Wi-Fi" it should be the first thing on the side menu. Go to the bottom of that screen and click on advanced. From there go to the wifi network that isn't working for you and click the minus button to remove that wifi network from your system's memory. Then just try to connect to that wifi again. It might not work if it doesn't let me know and I can find another way to help. 🙂
