So I have done a full factory reset and I am still unable to connect to the internet. The Wi-Fi says connected but I can’t open a page on Google? Samsung Galaxy tab A model SM-T355Y
Sound like a DHCP issue. Could even be the router refusing to give the machine a new lease. Have you tried resetting your router? This sounds crazy but I’ve seen this happen where the router thinks the device is already registered and refuses to hand it a new IP lease.
