My tablet wifi will not turn on i already try to hard reset it

Try holding the power button and the volume up button same time when hear a vibrate realise them both

already answered it

It sounds as if you simply need to reconnect to your wifi network. If you have already connected to it, but still have no access, then disconnect from your network, remove the network from your settings (Forget The Network) and then try reconnecting to it.

1. With the Samsung Galaxy TAB turned off, press and hold the VOLUME Down button, and then briefly press the POWER button.

Note: If you see "Downloading" on the screen with an Android shoveling you pressed the wrong Volume key. Remove and reinsert the battery and try again.



It should hard reset any of these tablets:
Reset GT-P6210 Galaxy Tab Plus 7.0 WIFI
Reset GT-P6200 Galaxy Tab Plus 7.0 WIFI + 3G
Reset GT-P6810 Galaxy Tab 7.7 WIFI
Reset GT-P6800 Galaxy Tab 7.7 WIFI + 3G
Reset GT-P7310 Galaxy Tab 8.9 WIFI
Reset GT-P7300 Galaxy Tab 8.9 WIFI + 3G
Reset GT-P7510 Galaxy Tab 10.1 WIFI
Reset GT-P7500 Galaxy Tab 10.1 WIFI + 3G

remove the battery for 10 seconds and reinstall again

Make sure the charger is plugged in before attempting this. If already plugged in or same thing happens then you can try and follow the guide as below to do a hard reset:

Hi if Volume up & power button doesn't work TRY Volume down & power button for aprox 30 seconds.cheers

If your having problem like this I suggest that you perform a hard reset. To hard reset just simply follow this step.
And remember reseting can delete your all access data specialy passwords and code.
To hard reset:
1. Turn off the whole system.
2.Hold together buttons: Power + Volume Down. In several second until logo appear on the screen.
3. Release the buttons. And without asking and without notice System will automaticaly doing a reset.
If this will not succesfull, try to create google account on PC. Then remember all information you've made, the email and password. You said system asking you to sign in to google. Use all information you've got to sign in.
Note: The google method is not working on other tablet, but most of it solve the problem. Then you should go to area where you have an a access of wifi, place where can you connect a wifi. Internet connection is realy realy needed.
Hope it will help.
