You want a cable/DSL router with a built in switch.
They sell for under $50 (US) at most major electronics stores.

You need the router because it allows you to share a single broadband connection among multiple computers.

A hub is just a tie point for multiple network connections. All connections to a hub split the available network bandwidth.

A switch is like a hub, but smarter and more sophisticated.
A switch allows the connected PCs to have as much of the available bandwidth as needed.

TheChas is right again

I have a Siemens Speedstream SS2604
it has 4 ports amd a printer port
I have had no problems with it for over 3 years
works great.
Note this is a wired model.
Siemens do have wireless models

Good Luck

this is not aol, is it? if so, call aol for help.
if your dsl is up and running now, you have a router. if it has 3 or 4 or 5 ports all in a row on the back, plug in your computers there with store bought ethernet patch cables of adequate length.
if you have dsl modem/router now, the way you make more ports is: plug router lan connection into hub or switch uplink port. connect other computers to remaining available ports on switch/hub. you may find you can't get link light without a crossover cable even on uplink port after resetting switch. read instructions because of gotchas like that. home networking advice/instructions www.linksys.com fairly generic have the answers you want.
if you havent' ordered your dsl yet, tell phone company you want to connect several computers (they let you have a few without declaring you a business) they will sell you a dsl modem/router with switch builtin or maybe trade up for what you have. then you will just need thernet patch cables.
hub and switch are same except switch is 'active' can examine ethernet traffic and and can configure 'private' connection to each port on the fly to keep from broadcasting conversation to all computers. less traffic=less collisions=less rebroadcasts=faster. hub is passive and blats traffic to all its ports. you won't see much difference unless doing video from several computers imho. pretty much hubs are passe. mostly you see switches now.
router gives you nat. nat is what lets router sit at public ip internet address and route conversation to private lan addresses (your computers). because internet requires each presence on it to have unique ip address. nat lets you stay out of direct 'sight' and allows a single unique ip address serve many computers. so routers have lan side and wan side connections and configurations. if using router in bridge mode: no nat. but i digress. routers can also have builtin firewall and logging capability and allow port forwarding and more depending on router model.

If you have a Westell DSL modem post back and let me know. There is some trickery involved in getting a Westell modem to play nice with a router. It's easy if you know how and nearly impossible if you don't.

Re Answer 7.

To use a Westell modem with a Linksys router, the modem must be configured to Bridged Ethernet instead of PPoE. Settings are found in advanced (?) settings under configuration if my memory is correct.

The router passes your user ID and password to modem.

I also have Bellsouth DSL.

No experience with your router, but it may be worth a shot.

To share an internet connection you need a router. what the router does is use NAT [network address translation]for sharing the single ISP assigned IP address. ALL computers on the local area network must have its own IP address and what NAT does is translate the LAN computer IP address over to the ISP assigned IP address. This is what allows you to have mutiple computer sharing a single ISP assigned IP address. Without NAT, you would need a seperate IP address from your ISP for each computer you want to have internet access. A hub or switch does NOT have this capability. A hub "broadcasts" inbound packets to ALL ports e.g. to all computers connected to it in the hopes of finding the right destination computer. A switch can read a packet header and determine that the desitnation of that packet is connected to port 1 or port 2 and send it right to the port unlike a hub which sends it to all ports.

A router is capable of examining a packet, and add information to the packet such as what NAT does [it also can strip away packet information] such as in NAT. For outbound packets the router ADDs a frame to the packet which give the Public IP address assigned by your ISP as the host portion and whatever IP address is the destination address, and sends the packet on it's way. Conversly for inbound packets the router strips away the NAT frame to find the original IP address[your local computer address] and then sends the packet to that computer.

Again, neither hub nor switch can do this.

What answer # 6 isn't telling you is that one box has to act as a router with 2 NICs amd by running ICS. Further, that box has to stay on all the time for the other computers connected to the switch or hub to have internet access. Turn the box hosting the ICS off and all other computers lose internet connectivity. One computer hosting ICS is a pretty expensive router considering a router only costs around $50 to $60 USD and a basic computer these days cost around $500.

Your choice should be a router. While you can share an internet connection with a hub or switch, the added security of a router makes it the only choice. Yes, you can use NAT with XP without a router. Are all your PC's using XP? Are you planning to wire them all together, or are some going to be wireless? Makes sense to get a wireless router/switch combination to cut down on the number of boxes to manage. If you a just building a wireless network, consider making all the pieces Wireless-G, with Turbo or 108mbps speed. If you do any file sharing between PC's, you'll be glad you did.

Willcomp mentioned in an earlier answer that a Westell DSL modem and a router can be tricky to get to work together.
I have a Westell DSL modem (6100 series from Bellsouth)and a Netgear router (FVS31 and I have problems. My connection drops and the router does not seem to reconnect. I have tried different timeout values for the Idel timeout (including 0) but it does not seem to help.
Any hints are appreciated.
