Samsung Galaxy S3 Network Authentication Faliure?

My phone was on the wifi and working just fine watching YouTube. All of the sudden it stopped loading and I noticed it wasn't on the wifi anymore. It said authentication error. So I typed in the password again just in case it forgot it, still said authentication error. I restarted it, turned off wifi, forgot the connection, turned back on wifi and nothing. I have since also rebooted my wireless router and I have tested the wifi from my laptop, and it works fine, what do I do at this point, make no sense to me.

    Try connecting to another wifi network. See if you get internet on any other wifi source. If you do, it is probably something wrong between the phone and the modem for your internet.(Setting was changed) Try calling the phone company as well. See if they can diagnose the problem. If they can not solve it, see if the cable company/internet provider can detect any issues.
