S5 connecting to router but not the internet


May 18, 2017
My rooted samsung S5 has behaved faultlessly for 3 years until yesterday. Now, it connects to my router but not the server (internet). All other android devices in my house connect to the internet without issues through the same router.

I have uninstalled a couple of recent apps . and tried WiFi Fixer . . but still the same. .

Most grateful for any help
NOTE: I know you said all other devices work connected to the router/modem, however that is really very common for all others to work and one not work.

1. Try and restart the phone. Sometimes it is that simple.

2. Update the firmware and any apps that need updating on the phone.

3. If the problem persists, check your time and date on the phone to make sure it is correct.

4. Should none of the former work...
a. Clear out the WiFi data on the phone.
b. Reboot the modem/router.
c. Once the modem/router is fully 'up' again, reboot the phone and re-input the WiFi data.

5. Now, if you are still having the problem at this point, and you are sure it isn't the modem/router that is the problem. Then you may wish to try a "Hard Reset" of the device. However, I really suggest saving this as a last option (or last before parts repair/replacement).

NOTE: Doing this will clear 'all' the data on your phone, so it is suggested you not choose this option unless you have to, or aren't worried about losing anything on the device.

Be sure you back up any data you want to keep, to a computer or cloud account, before doing the reset.

To "Hard Reset" the phone...

1. Make sure that the phone is actually powered off.

2. Press the "Power" and the "Volume Up" buttons, together, until you see the start-up logo on the screen.

3. Once you can see the logo, release the buttons and allow the device to enter the "System Recovery Mode".

4. Next use "Volume Down" button to get to the "wipe data/factory reset" option When in recovery mode the "Volume Up" and "Volume Down" buttons are how to can navigate and highlight what option you need.

5. Once you have selected the "wipe data/factory reset", press the "Power" button to select that option.

6. On the following screen, repeatedly press the "Volume Down" button until the "Yes - delete all user data" option is what is selected.

7. Then press the "Power" button to hard reset the phone.
