I would love to replace these "routers" with a normal computer. The thing is these computers would need special ports for either phone lines or fiber optic connections, as well as built-in modems. I've never seen a computer with this sort of hardware built into it. Even on dedicated network cards I only ever see ethernet ports, nothing compatible with whatever it is my ISP is using (SFP?). Decades ago in the dial up days I used to be able to buy modems separately but not anymore, and I'm not even sure what sort of hardware components are needed for a fiber connection...
