Disconnect cable from doorbell?

I recently tried to install a Ring Peephole camera and am having no luck at all connecting to the internet. I am trying to troubleshoot and my first step would be to try to connect closer to my modem. So, I am going to ask a beginner question: Can I just disconnect the cable that connects the outer video cam to the inner casing of the doorbell? I'm guessing that you can, but I also noticed I got a replacement cable in my packaging so I'm not sure if it's a backup or if removing the connection damages it somehow.
