Moved into 2 bedroom apartment with friend. Network wall panel is in my bedroom closet. I put my cable modem in there, then an ethernet cable to the jack with leads to the living room. I plugged in my Airport extreme to living room jack and great, the entire apartment is getting faster speeds than I signed up for (+100mbps). Roommate has a VoIP phone and for some reason doesnt want to plug the little box for it into the ethernet port of my airport extreme (we have yet to test how well that would work). He is talking about setting up a separate wifi network. I suspect he wants to fiddle with a bunch of settings like data priority and such based on what he is saying. Well I dont want to move my Airport to the closet for obvious reasons, and I dont want my Airport to be a slave to whatever router he would hook up in my closet (and control the settings of considering I am paying for the internet bill). Could we just do something like this? cable modem, Ethernet cable to network switch (like this: http://www.bestbuy.com/site/searchpage.jsp?cp=2&searchType=search&st=network switch&_dyncharset=UTF-8&id=pcat17071&type=page&sc=Global&nrp=&sp=&qp=&list=n&iht=y&usc=All Categories&ks=960&keys=keys ), 2 Ethernet cables into the jacks from network switch, one to living room to my Airport for my network, the second to the 2nd bedroom so he can set up his router in there and have his own network and mess with settings to his hearts content without affecting me. Would that work? I read that I may or may not need to ask Time Warner Cable for another IP address? OR, if that wont work, would this?..... cable modem, Ethernet cable to network switch , 2 Ethernet cables into the jacks from network switch, one to living room to my Airport for my network, the second to the 2nd bedroom so he can plug in his VoIP phone and we can be done with the situation.
