I connected the phone to my wifi. But it wont go to any websites or mail etc.

Hi Shiela

Try the following as sometimes it's a simple setting missed..

Solution-1
On your phone under Settings>> WiFi >> Hold the Name of Your Network >> Now Click on Forgot Network.
Now reboot the phone & modem/router and try to connect the Wi-Fi again.

Solution-2
Pull out the phone battery while it is working & re-install after 30 second. Phone will reboot again now try to connect to network and check internet connectivity.
Solution-3

You can browse to Settings>> WiFi >> then press left menu key & Click on Advanced. Now check that Wi-Fi timer is not off. If Wi-Fi Timer is on then turn it off.
Now disable Wi-Fi & again enable it. Now check the connectivity on Android.
Solution -4 (Important)
Update your phone, Modem& Wi-Fi Router time and date to match the internet provider time and date. This is very important because 2 out of 10 cases are because of this issue.
Solution-5
Check the Internet connectivity after disabling the antivirus & mobile data.
