I only have one computer with a comcast modem but it asks me which network to join?

Percy Seiger: Just choose Home

Oren Eskelsen: The labels used for the network locations are pretty much self-explanatory. The Home option doesn't necessarily need to be used for a home network, but rather when users can trust the computers and devices the machine will connect to. This is also the only option that will allow for the Windows 7 computer to create a HomeGroup, a feature designed to allow users to share and access content among Windows computers.A Work network is by definition a tad more limited than a home network. In this regard, although network discovery is enabled by default and computers and devices are visible among all users, a HomeGroup cannot be created. Choose Public network for networks in public places (such as coffee shops or airports). This location is designed to keep your computer from being visible to other computers around you and to help protect your computer from any malicious software from the Internet. HomeGroup is not available on! public networks, and network discovery is turned off. You should also choose this option if you're connected directly to the Internet without using a router, or if you have a mobile broadband connection....Show more

Lynn Melbourne: Jeez, this is not rocket science. If you pay for another connection you will get the same service levels on both machines. Cable IS is a shared medium so it is no worse than when your neighbor puts in their own cable modem. The advantage to two modems is with the upstream limiters put in place to limit the bandwidth to a single modem. So theoretically you have more bandwidth available. Practically the cable segment is probably oversubscribed to a point where limiters are not often needed as the overall customer load on the segment limits the actual throughput. Is the possible performance improvement worth it? Maybe, but do not get your hopes up. Where you might see an actual issue in implementing this solution is with the signal levels. By! splitting the cable you add a 3 db loss at every split. So by! doing so you will lessen the signal to both devices. This is not necessarily a real issue unless you already have a marginal signal. Normally high quality cable and splitters will do the job, but a $100 bidirectional cable amplifier will deal with most signal level issues....Show more

Donny Bankson: Its a system default, no worries. Most likely you have multiple connections available in the back of the modum. You could technically plug in more computers in your house to it. A home network would allow all computers to see each other and exchange info or stuff if you wanted. (like files or music) Usually i use public, i have two laptops and a pc inside my house but i dont want them to share anything but use the same internet connection only. IF however you get a printer later and you connect another computer you would have to have a home network to share the printer with the other computer. IF you only have one computer at home and that is all you will have. You can go! public....Show more
