@johnpoz:
And what card to you have exactly? http://www.amazon.com/dp/B00EKQN2KK/?tag=pcpapi-20 And what is your N router? http://www.linksys.com/en-eu/products/routers/WRT160NL Most cards are 2x2 streams at best. Do you have AC clients? If not that card having AC gets you nothing. Where did you get the card, someone gave it to you for free? My Dad's office motherboard died. Because AC pc cards are not all that cheap. Never in my life seen a dual band card that would allow you to have both 2.4 and 5ghz up a the same time, etc. This is exactly why Im doing this. To Learn. I did not know this
You do understand 5ghz N and AC is only 5 is lot less coverage than a 2.4.. So sticking some little card in a box you have in the corner is not going to give you much coverage.
I told you. My house is not large and my home office is centrally located on the second floor.
I am all for experimenting.. Please do fire up pfsense its a great product, and I love running mine on esxi.. But wanting to use it as an AP is just not something you should be toying with to be honest, not when you could pick up a dual band N access point for pennies.
Why exactly should I not toy with it? What will it hurt? Im going to be honest with you here. After have my idea being called "beyond stupid" and this post here, I feel Im being attacked for asking a question and wanting to try something. I know I can't read tone and body language through text so I could be taking this wrong but I dont think so.
If your going to want to play on improving your network - trying to stick some pc card into your host and use it a AP is just not the right road to go down.. That is my personal and professional opinion, take it or leave it.
