I am also facing the same issue, I am having the Samsung Note II. Earlier Wifi was very working fine but now it is not working that good i.e. gets disconnected in few mins, not able to download videos/ send messages thru Whatsapp. Somewhere I read that it is due to switching from Android 4.1.1 to 4.1.2, not sure though...
if anyone finds the soln please do let me know, thanks.
