Why is my wifi turning on and off (Galaxy S5)?

[AC Question]

Explanation of Galaxy S5 Wifi issues

I had this phone since May and kept it in perfect condition but It all started Thursday, i got home and noticed my phone switching on and off wifi, not updating apps, no fb messager notifications, and not searching for update.

I have T mobile and people say just turn off smart Wifi switch and i did but my phones slow with those problems while on Wifi still even with a 100+MB connection.

When Wifi is off though it works perfectly...

Anyone else having the same problem or have a solution?

Welcome to Android Central! Have you also done a cache partition wipe? http://support.t-mobile.com/docs/DOC-10404. A reboot of the router might be in order as well.

Just had an issue with mine doing the same but had to take it off where it would switch back and forth if Signal was weak. So house is wifi and if I go out it will then go to lte. Not sure if this helps.
