So let's say I use some local company that is a fly-by-night operation, and my mom's on Verizon (no idea). If I reset my router, will it work? Or am I completely ****ed regardless because our providers don't match?
IJAG, Short answer is you will probably be fine.
Your ISP nothing to do with anything. The router will work with any WAN (wide area network, or internet connection).
The question is how you have the router set up. Home routers do two things: They take an internet connection to multiple computers and they allow multiple computers to communicate to each other through a network.
If you just took the router out of the box, hooked it up to your cable or DSL modem and hooked a few computers up to it--and didn't change any settings so that you are encrypting data (would have required you set up each computer with the encryption key, so you will know if you did this)--then you shouldn't have any problems taking it somewhere else, hooking it up to their high-speed connection and using it to share the connection. What the router is likely doing, is attaching itself to your ISP IP address, assigning a standard IP address (usually 192.168.1.1) to the router and using the DHCP protocol to attach an IP address to each computer (usually something like, 192.168.1.100, 192, 168.1.101, etc.) so they can communicate with the router.
Chances are you won't have any problem at your parents' house, but bring the manual with you.
By the way, I have no idea what it's like where you live, but where I live I'd never leave a wireless connection unencrypted. Some of my neighbors stupidly do and the signal reaches my living room. I could take control of their computer if I wanted, or piggback off their ISP connection and do something illegal, like trade kiddie porn, if that is the type of person I was. And when the authorities came looking for someone, it would be them, because the ISP's IP address was assigned to their cable or DSL connection.
