The strangest post ever. Why did you mention Cisco certification? The funny thing is - I'm preparing myself for New Cisco Certification and I know something about networks. I already know a lot of stuff about networks. But I can't help you. Why? Because I don't know the model of your car, that's why. Without this information I can't give you advice. The only thing I can tell you without information - buy a router. Just go to the shop and buy a router. And yes, tell them the model of your car before you do so.
