So I'm moving back in with my mother (financial reasons for us both) and need to figure out how to get internet to my mother/brother (upstairs west side of house) and myself/girlfriend (basement east side of house) knowing that wireless in this circumstance is pretty subpar for either party. My brother is mentally challenged and is on his computer unless he's sleeping, and I'm...on an MMO forum...so yeah. I used to just run a 100' cable from upstairs all the way downstairs and had two routers, but my mother is adamant about not having any cables showing, and I gave that cable away anyway. So I was thinking about officially wiring the house, and need help with things such as: Which cable to use (cat 5e or 6?) and whether I should do this myself or find someone to do it for me.
That's a pretty rough sketch of the top floor, without doors plugged in. In the basement my "living room" is essentially where the master bedroom is, so that's where my computers will likely be setup. My plan is to go for Cat 6 cabling to "future proof" the house, but may want to use 5e for costs anyway. I've done some basic cabling work in an A+/Network+ course I took in high school, but crimping wasn't exactly my specialty, so I'm a little worried about that. Also, I have NONE of the tools for this job.
My plan was to setup the box in the "linen closet", take cables up into the attic and shove them down to each room there, then try to shove a cable or two all the way down into the basement, that wall with the linen closet aligns with where the water heater/furnace is in the basement, which is not insulated and somewhat "open" so no holes would need to be made on that end. I could probably get by without having to hide the cables that get into the basement, too. Then I just find some network jacks and I have networked my house, roughly, right?
So aside from which cable to use, is this too much for someone who has never really done something like this before? How much do you think this would cost me? (let's say 4 rooms upstairs and 1 downstairs) professionally or just in parts/sanity? And should I just shove one cable all the way downstairs and split them, or should I send 2-3?
