Why does my wifi keep dropping out?

[AC Question]

Wifi keeps dropping out

Samsung S5 since downloading upgrade to lollipop 2 days ago both mine and my husband's phone keep going in and out of wifi connection. Also completely losing network connections for a couple of seconds. Both phones were fine prior to the upgrade. No problems with tablets, laptop or iPhone.

Welcome to Android Central! A common complaint so far. Go to Settings>Wifi, tap Menu>Advanced, and turn off Smart Network Switch.
