I'm sorry about the issue. Does your Nexus 7 ask for the wi-fi / wireless password?
What is the model of your Internet modem/router device?
Are you able to check / confirm your Wi-Fi / wireless password ***** key, if any?Do you have a laptop / wireless computer that is currently connected via wireless? If so, does it have Windows xp, vista, or 7, 8, 10, or Mac?Please type at the box below, then click on the Send button below to communicate with me, so I can help. Thank you,
