It assigns an IP address to your PC that is determined by your ISP. PCs connected to the Internet via an ADSL modem are vulnerable to hacker attacks. An ADSL modem/router is an ADSL modem plus a router. The router acts as an interface between your internal network and the Internet. It is like a barrier: Your internal IP address (e.g. 192.168.0.10) is not visible to the outside world. It can therefore be used by several PCs connected to the internal network. It's much harder to hack through a router than it is to hack through a modem. Most ADSL modem/routers have several output ports but they don't have to. If yours has only a single port then you need to buy a switch so that you can connect other PCs too. Switches are very cheap these days.
Guest Peter Posted August 7, 2007 Posted August 7, 2007 How to share Internet ? I just get a 1 port ADSL modem router from the ISP. From the specification, it says that I can use it for Internet sharing. However, as there is only 1 port (1 port for connecting ADSL signal and 1 port for Ethernet), I would like to know why they say that modem is a router ? From my basic understanding, a router should connect more than 1 machine. Thanks

From my basic understanding, a router should connect more than 1 machine. It sounds like you have an ADSL modem that is not a router. My understanding of the language in the specification is that they are saying that you can use it with a router, which you can. Home routers are widely and cheaply available, and many have wireless capabilities too. When you get a router, you'll connect it to your ADSL modem with a single ethernet cable. Be careful to get that cable into the proper port on the router! The router will have multiple (probably four) other ethernet connections that you use to connect your computers to it. -- Tim Slattery MS MVP(DTS) Slattery_T@bls.gov http://members.cox.net/slatteryt

I have seen several ADSL modem/routers with just a single port.

Here's a cheap, simple example (we're talking $15.00): http://search.ebay.com/search/search.dll?sofocus=bs&sbrftog=1&from=R10&_trksid=m37&satitle=befsr41&sacat=-1%26catref%3DC6&sargn=-1%26saslc%3D2&sadis=200&fpos=77072&sabfmts=1&saobfmts=insif&ftrt=1&ftrv=1&saprclo=&saprchi=&fsop=1%26fsoo%3D1&coaction=compare&copagenum=1&coentrypage=search&fgtp= This is for a Linksys BEFSR41 switch. Not only does this device make the process painless, but it adds a hardware security layer, preventing outside intrusion via your internet connection.

No, a switch is not a router. Routers will perform some IP address translation but switches won't: What comes in goes out.

Sounds strange to me. As OP said, a router allows multiple computers to connect to it and switches packets among them. This thing has only one ethernet connection, so you can connect only one computer to it. What kind of router is that? -- Tim Slattery MS MVP(DTS) Slattery_T@bls.gov http://members.cox.net/slatteryt
Guest Gary S. Terhune Posted August 7, 2007 Posted August 7, 2007 Re: How to share Internet ? If such an animal exists, it's a cheap one that requires an added network switch to distribute to more than one device. A router does a lot more than just switch packets to the destination. What we normally think of as a router is a router with a built-in switch. -- Gary S.

A "switch" (in this context) "is used interchangably with router, but 'switch' is really a marketing term without a rigorous technical definition (though a switch is commonly understood as a network hub with switched ports, which might or might not also perform additional routing functions)."

Plug your PCs into the switch, and plug the ethernet cable from the Router into the switch. it's as easy as that...
