My husband set up a Netgear router to hook his computer and mine to the internet. My 2 sons and I all have the same Android tablets and we could hook all of them up to the internet through the router. Recently, he unplugged the wifi from my computer since I'm getting a new one, but in the meantime neither myself or my 2 sons can get back on to the internet, even though the home computer is still connected. I have taken my tablet, gone into settings, forgotten our home netgear address, shut off the home computer, my tablet and our router, restarted both devices, turned the router back on, had the home computer connect to the internet, and retried to connect to the internet from my tablet, none of our tablets reconnect. What am I doing wrong? I am not tech savvy, but have been trying to connect my tablet for days now.
