I can only guess it's blocked at work or they use WEP which can do what you noted. Remember I will not guess it's some DNS since, well that would not happen with the stock settings.

I have a Samsung note 2 and a tab4, the internet connections work fine except where I work. At work, my devices say that they are connected but they don't actually work. The wifi ingoing/outgoing signal icon on the toolbar shows full connectivity, but the outgoing arrow does not appear. So, it seems it is getting the incoming internet signal but for some reason won't send an outgoing signal. How can i fix this?
