I have just bought a nexus 7 (2013) but cannot connect it to the internet. After turning the device on , it finds the local network but, when I try to connect, I get a message saying a webpage is not available. I tried rebooting with no improvement. I looked on the internet and found that many people had encountered this problem , but there was no solution offered that worked. I went to the local library to check it out on the WiFi there but got the same result but with a different web address (particular to the library)on the error message. I reset the factory setting ( just in case I'd had a slip of the finger somewhere) but it did not help.
If anyone has any (useful) suggestions I would be pleased to hear them; otherwise, the tablet goes back to the shop tomorrow.
