Wi-Fi connectivity issues

In the past week (perhaps longer) my Note 5 loses Internet connectivity while on WiFi while other devices on the wifi network are fine.  This has happened at home and work.  The icon shows wifi is connected with a strong connection. Turning wifi on and off or toggling airplane mode don't fix the problem. If I restart the phone, however, connectivity will be restored.  I've had the phone since it's release date and don't recall this being an issue before the last week or two.  Anyone know how to fix or troubleshoot  this?

Try this:

Settings > Wi-Fi > Menu (3 dots) > Advanced and then turn off 'Smart network switch' if it is on.

Please re-test.

If that fails, please retry in Safe Mode.

With the device powered on, press and hold the Power button (located on the right edge) until the Phone options prompt appears then release.


Touch and hold Power off until the Reboot to Safe Mode prompt appears then release.


Tap Restart.

The restart process may take up to 45 seconds to complete.

Upon restart, Safe mode appears in the lower-left of the unlock/home screen.

Re: Wi-Fi connectivity issues

Smart Network Switch is not on.  Safe mode disables downloaded apps so it would seem to be hard to test?  It is an intermittent problem.  Any other way to generate logs or launch something to debug it when it occurs?
