Modem/ Router for inside a computer

[planeguy102]

Does anybody know of a PCI-E based router/modem that can be used inside of a computer? I want to make my server take over responsibility from my crappy Xfinity router, so I want to have a router that can be plugged into the computer, receive coaxial signals, and output one hardwired port (network switches can do the rest.) If not, could somebody also tell me if there is a way to configure a wifi card to work as a wireless access point? thanks.
