Hi. I've a new Samsung Galaxy S5 SM-G900F with Android 4.4.2 . The phone is great but there is 1 annoying problem. Every time I connect to my home wifi it automatically disconnects after a brief connection. If I try to connect with any other gadget eg laptop, my wife's Sony Xperia, Tab 3 there is no problem at all. I once Googled and found what appeared to be the fix - that's dialling *#0011# and turning off power save mode. That helps but once I log out and try to log in again, the problem pops up again. surfing the net with mobile data has no issues at all - just that it's damn expensive :-/ Is there anyone experiencing the same issue, do I need to update the OS, what's the way forward?

Later found out that I had installed a firewall that was causing the wifi to drop! Deactivated it at once
