My origin is not connecting to the internet

I am having the same problem. I've tried working with my firewall settings and letting origin past my firewall. I've tried reinstalling it. My origin has been "Offline" for weeks and I finally got the Sims 4 and tried installing it and, turns out, you need origin to be online. Big shocker. However I would be really pleased if someone could post a very detailed solution that would work. I know I'm not helping, but I need a solution. I've been all over the forums and each thread that says "SOLVED" on it has not worked for me. I don't know what to do. My aunt had the same problem with installing her copy too, Origin was offline. She talked to the EA Support team on facebook and they helped her fix her problem. I tried what they suggested and nothing. Origin is still offline. What am I supposed to do? Someone please help, Thank you.
