Galaxy S5 Lollipop WiFi Disconnection Fix

Last week Three rolled out Android 5.0 Lollipop out to the Samsung Galaxy S5. Although I should have probably waited to review the general feedback I opted to install this on the day of release, however soon I noticed that there were some serious WiFi problems post install – don’t worry I found a simple fix!

Having owned my S5 since mid 2014 I had been happy with the WiFi, in fact I’ve barely had an issue with it, aside from it’s plasticky exterior when compared to other flagship handsets from competitors. Therefore I felt short-changed when my home WiFi became impossible to use.

I was seeing very sporadic connections and disconnection from my home WiFi, which meant video streaming was particularly annoying. My homes wireless network has easily had 30+ devices connected to it over the past year or so, therefore I knew Android was at fault – one thing to note was that this was still apparent after a factory reset (standard practice whenever I install any major software update.

To fix this problem all I did was go into Apps \ Settings \ WiFi \ here there is a setting called “Smart WiFi switch” (see image below below), I must confess I am unsure if this was here prior to Lollipop, but seemed to be “On” by default post update.


Ironically it is supposed to help maintain a stable Internet connection, this is apparently achieved by automatically and intelligently switching between WiFi and mobile networks as well as 2.4GHz and 5GHz bands – sorry Google / Samsung, it didn’t work as desired for me!

Now there is a chance that the admittedly average wireless router at my house was at faulty, but after searching around it seems as if this is quite a wide-spread issue, so be sure to switch off this feature if you’re affected.

Did this fix the issue for you? Please let us know by leaving a comment below.
