| Can we build a dedicated PC to use as just a router and wireless router for our home instead of using a store bought router?|
How's your knowledge of Linux and UNIX?
Presently where I work we're switching over to prebuilt devices but for many years now our firewall/routers were redundant (teamed) OpenBSD based boxes.
I'm presently building one at home using FreeBSD for my home LAN. I'm going to put it between my SOHO router and the rest of my LAN or even replace the aging SOHO router altogether. I'm still figuring how best to setup pf filter and once I do, the old PC it's running on will be going into production.
Most all (if not all) flavors of Linux and both Open/FreeBSD can route and have pf built in.
As far as the wireless side goes, if you added a wireless NIC you could use it for wireless but it may be a lot simpler,and more sensible, to simply purchase a wireless AP (or more depending on your needs and the space you're going to cover) and connect it to your LAN.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
