Samsung galaxy a3, Wifi issue

I have a samsung galaxy a3, i recently updated it to android lollipop. Ever since then, when i connect to my wifi, it gets connected but after some time i get a message saying i have to sign in to the network. When i touch the message it just opens my browser and goes to the homepage. Please help me.

Re: Samsung galaxy a3, Wifi issue

Welcome to Android Central! Does that happen on other networks, or only your own? Do you have Xfinity (Comcast), and does your router broadcast a public Xfinity hotspot? Perhaps your phone is losing connection briefly with your main network for some reason, and connects to Xfinity instead briefly (which would require you to sign in with your Xfinity username and password).
