I'm trying to share the internet connection from my cable modem with my housemates. We already share the cable bill for TV, but until now I was the only one who wanted the broadband cable internet so I've been carring that part on my own.
Now that we would like to make the single connection available to each of our computers, I'm in the funny position of trying to come up with a way of doing that without linking our computers together. For pretty good reason I'm more worried about my housemates accessing my files than a random hacker on the internet, so I don't want to set up something that makes my system any more vulnerable to them than it would be if we lived in 3 seperate homes and had three seperate interent connections. I'm also pretty worried about getting a virus or two from them, since they are not careful what they download and were always having problems with viruses before we got the house.
It really doesn;t matter if it is wired or not (but my landlord would probably be happier if I don't drill any holes), so if it is cheaper wired or is only available as a wired product that would work.
If it can be done wirelessly, is there some sort of system that can be setup where each of three computers can have acces to the internet over a single cable connection where it would be comparable to 3 guys who didn't know each other sitting in a wifi hotspot?
If wired, could a single cable connection be setup so it is comparable (without concer over loss of speed) to 3 next-door neighbors each getting cable internet?
This may be a totally stupid question that anyone sould be able to figure out. But from what I've been able to find out about routers, it's not clear if I can use one just for internet sharing without some sort of more involved networking. If possible, I'd rather not just set up a network that doesn't allow file sharing but does share the internet connection, as that would provide one more possible route into my computer than us all simply being on the internet at the same time. Because of the layout of the house, it is very likely that I would have to have any router type hardware in a physically accessible spot.
Thank you for any one who can help me figure out how to do this.
