SOLVED: Galaxy S5 WiFi Keeps Disconnecting After Lollipop Update

I received a lot of emails regarding the most recent WiFi problem with Galaxy S5, which started after Android 5.0 Lollipop update. According to reports I received, the phone can connect to an WiFi network without a problem but after a few minutes, the connection will drop, then the phone will attempt to reconnect. This cycle will continue unless and it will drain the battery way quicker than normal.

Galaxy S5 WiFi Disconnecting


Hi. Can you help me? My Galaxy S5 was updated to Lollipop. The update went smooth but after the installation, my WiFi keeps dropping and reconnecting to the network. I am positive of this because it never happened prior to the update.” — Sean

I got a notification that an update is available so I duly downloaded it. After the update, my WiFi connection became crappy. So, I did the factory reset in hopes that it could fix the problem. It didn’t. I’m at my wits end here, so please help me.” — Cassandra


I understand the issue is very annoying but it’s not really a serious issue. The Galaxy S5 has a feature that allows it to scan for available networks (both mobile data and WiFi) and connects to one that is more stable or has strong signal provided that both WiFi and mobile data are enabled.

To fix this issue, you have two options: either you turn off mobile data completely or prevent the phone from automatically switching between networks. Personally, I will prefer the latter because mobile data is necessary for MMS or picture messages. Here’s how…

  1. From the Home screen, tap Apps icon.
  2. Tap Settings.
  3. Tap WiFi.
  4. Now, make sure the Smart network switch checkbox isn’t ticked.

That’s pretty much it! Leave a comment if you think this is helpful. Thanks for reading.
