Samsung Galaxy S5 Wi-Fi Connectivity Problems After 4.4.4 Update
My Galaxy S5 has had no connectivity issues at all. This morning I installed the 4.4.4 update and immediately began having wi-fi connectivity issues. The S5 keeps dropping the connection and then reconnecting. This is constant.
Obviously, the signal was strong enough and constant enough that I was able to download the 487 MB update with no connectivity problems whatsoever. Now, however, when I check Wi-Fi networks, I note the S5 is constantly scanning. Is that normal?
None of the other devices using Wi-Fi on this home network are experiencing connectivity issues, including a netbook, a tablet, and a Kindle Paperwhite e-reader. According to the S5, the signal is "strong," yet it continues to drop and then reconnect.
I have tried the S5 on other networks and the same problem exists. Others are experiencing the same problem after installing 4.4.4. Unfortunately, a number of us posted in an earlier topic, which had been marked solved; therefore, our posts may likely go unnoticed.

I think you probably meant to say uncheck the "Smart Network Switch." Yes, that does help in most cases.

I'm not an AT&T subscriber (sorry) but am still having wifi connection issues. Just upgraded the OS on my Samsung 5 hoping it would fix the issues but it's even worse now.
my phone is constantly scanning for a wifi connection (battery drain) and even when it finds a wifi connection (i.e., at work) it keeps dropping the connection, even though my work wifi is a securem, password-protected connection for which I have direct access.
How do I fix this? It's so frustrating! I wind up restarting the phone several times before the wifi connection 'sticks'.
Any suggestions are greatly appreciated.

Make sure that "Smart Network Switch" is unchecked. Settings > WiFi > uncheck Smart Network Switch.
Also, wipe your phone's cache partition. Doing so will not delete your data, it will just clear out the cache, and that alone often resolves many problems: Turn off your phone then simultaneously depress and hold three buttons... the volume UP, the home, and the power buttons. Hold these three buttons in until you see small blue or green writing in the upper left corner, then release the buttons. Use the volume up/down buttons to select "wipe cache" or "wipe cache partition." (Do NOT select any other option!) Depress the power key to activate your selection and reboot your phone. The process will complete very quickly, probably no more than a minute or so from start to finish.
There's a very informative article here regarding Lollipop post-update issues and solutions. It includes the instructions for wiping the cache partition and other good advice as well. I've found it to be very helpful.

It is NOT the Smart Network Switch. I have not had this on and still have the problem of constant scanning and reconnecting to the home network. I've tried shutting down and replacing the battery - no effect. Have tried forgetting the network and reconnecting - no effect.

It is true that deselecting the "Smart Network Switch" will not stop the constant scanning, and it will not stop all of the dropping and reconnecting. However, you will not be wasting your data, which is what will occur if you leave "Smart Network Switch" selected as each time the connection is dropped, it will automatically switch over to using your data.
As annoying as the scanning and disconnecting/reconnecting is, it's less frequent with that option unchecked, and it won't be wasting your data.

To the best of my knowledge, there is nothing that can be done to stop the incessant scanning. It's inherent in the device itself. By deselecting the smart network switch, you should at least prevent your device from wasting data by constantly switching over to your cellular network each time it erroneously detects a loss of WiFi connectivity.
It's my opinion that the scanning issue will only be resolved when I replace my smartphone. The replacement will be neither carrier branded nor will it be a Samsung.

Did you go to Settings > WiFI and select your new network from the list, then key in the new WiFi network's password in the appropriate field and then click on "connect?"
