If you have serious issues accessing AKO from your home computer, try visiting this page, and it may help you solve the issue. It’s a step-by-step guide so it shouldn’t be too difficult unless you’re terribly technologically declined. That’s fine if you are, but let me know and I’ll post an update with a simplified guide.
This page might also help you access AKO using your personal CAC reader, although you had better have great security on your network. A good firewall might be come in handy. Unfortunately, they’re typically pretty expensive. If you’re running Windows 7, you should be alright.
