Discussions so far appear to be centered around hubs but since true hubs are just a means of connecting various machines on a LAN with no nat abilities they will not work in this case without the public id's mentioned. With a hub the ISP provides an IP address connections for each machine on your LAN. A router, Linksys BEFSR11, 1 port in and 1 out to your cable/dsl modem, or BEFSR41 with 4 ports, for your LAN computers, and 1 port out to your cable/dsl modem which will allow connection to 4 machines. In this case your LAN will obtain all IP addresses from the router while the router will obtain one IP address from your ISP and to the ISP you will only have one machine online. If you connect 1 port for a LAN machine to a larger switch or hub more machines can be handled. The only difference between a switch and a hub will be seen on your LAN when talking from one machine to another. If you have 4 machines you will be able to have 2 "private connections" between any combination of 2 machines running at full speed while with a hub you will run at the speed of the network divided by the number of machines connected. 10/100 running at 100 will give 25 as the network speed or half the speed of a switch. When connecting to the internet all machines will be sharing the 10 speed connection common to typical cable/dsl modems. Costs of these items can vary but the BEFSR41 can be obtained for $50 or less with sales appearing for various "old" models of similar devices being as little as $10, I have one from Microcenter in the LA area. 8 port switches, far preferred today due to performance, can be obtain for $15. I don't know where you are located but www.microcenter.com, www.acnt.com, www.actirvine.com, www.actcorona.com, etc. also www.computeruser.com is a magazine through which you can contact a number of Southern California suppliers or possibly get ideas for contacting local suppliers in your area. On the matter of wired vs wireless it is easier to obtain your privacy on a wired system since someone parked outside your home/office cannot simply logon through your wireless connection. If you go wireless make sure you read the security procedures for your device and follow them otherwise others can use your ISP connection for their purposes. They can also monitor everything you do on your LAN and over the internet for their own purposes. Your banking ID's, credit card numbers, etc. will be at risk without proper security measures in place.

Hello, We currently have an Ethernet hub on a LAN that allows us to share our 56K internet connection, and would like to upgrade to AT&T DSL Service. The question is can I make the upgrade without having to upgrade the LAN ? The AT&T phone person said I would to buy a wireless router. I dont understand the differnece between a wireless router and an ethernet hub. I would like to upgrade to DSL without having to buy a whole new network system.
Please give direction, RS
