OK, I've tried searching throughout the forum and Google but couldn't find answer to this. I recently changed my DNS on my rooted T-mobile Note3 to a overplay SmartDNS, but turns out that the WiFi of the place I work for doesn't like that. My WiFi keeps on failing to obtain IP address, (my workplace is high security kind of place.) So, I need to change the DNS of my phone back to the original default that was in my phone. Yes, I'm stupid (now I realize) that I didn't save the DNS before I changed it. Is there a way to figure out what the original DNS was?
