samsung tab 2 wifi problem

You may have to reset your access information, as many have a home WiFi they connect to automatically, so the phone.tablet recognizes this system and attempts to connect to it, even away from home.
You may need to go into your settings and select 'add network', and then check the appropriate configuration. You might only need to set everything to automatic and let the device do it for you.
Also, do you know what RF band the router/AP is using at work?
Your phone/tablet may be attempting to connect using a band the router/AP is not using, or not configured to use.
There may also be a log-in requirement before it grants you access, as many restaurants have.
A restaurant near me changed their configuration as well, and I had to completely redo the phone so it would connect.
Happy WiFi'N!

Try going into wifi settings and remove that location. Reboot and add it back.

 

Well, Like @Jeffrey said remove the Wi-Fi location , shut your device down and and then restart your device back again, now try connecting your device again ! this should definitely help you out if that still doesn't then i guess you need to contact the IT person at the work.
