So, what happens when I have a good idea? Nobody else has ever done it and I don't know how to do it and I have to learn all new things and then when I'm ready to give up, I find out people have been doing this all along and I don't even know how to Google, apparently.
The other week, I decided the little TP-Link MR3020 couldn't handle what I was tasking it to do so I bought a Raspberry Pi 2. After a week of fooling around and finding similar projects (https://hackaday.io/project/2040-web-security-everywhere) I decided I'd just follow someone else's instructions. I ended up going with https://realiesone.wordpress.com/2015/03/11/the-raspberry-pi-as-an-internet-pass-through-web-server-using-two-wireless-adapters/ for starters and currently have the device operational with the Edimax adapters. I'll test it out with the captive portal at work tomorrow night.
I still plan to tinker with this and maybe try some other builds but I'm gonna call this one done. Thank you everyone for all your support and I'll keep you posted if things happen.
