First, try restarting the Galaxy S6. To do that, hold the power button on the right side of the phone until prompted. Hold it down again to turn the Galaxy S6 back on. It's a simple process but it has been known to dislodge Wi-Fi issues
If that doesn't work, Galaxy S6 users will want to try rebooting the local router if that hasn't been done in awhile. We recommend unplugging the router for a good 30 seconds and then plugging it back in. Users can do the same for the modem as well. Galaxy S6 users might also consider updating the routers firmware. This process will be different depending on make and model. If those simple fixes don't work, it's time to head into the Galaxy S6's settings.
If the Galaxy S6 isn't getting a solid connection, it's time to force the device to forget the Wi-Fi network in question. To do that, head to the desired connection in Settings. On the Galaxy S6, this can be found in the Connections portion of Settings. Once there, select Wi-Fi. Tap on the desired network and select the Forgetoption. Users will then need to reconnect to the Wi-Fi network. Make sure the password is readily available or the device will be locked out.
If that doesn't work, head into Wi-Fi, tap More in the top right corner, and select Advanced. Ensure thatAlways allow scanning is turned on. You'll also want to make sure that Keep Wi-Fi on during sleep is set toAlways.

The wi fi networks are whatever is available in your home or public wi fi network. If it is a free wifi network then simply select it from your tablet and it should connect you up. If it is a secured network then it will prompt for the code that has been set up.
