dsl, plug modem into switch but only 1 computer can get internet at a time

[Chaoticknight16]

okay, so i told the sbc people i need dsl for one computer...i planned to, as i have, connected the modem into the hub which is then connected to 4 computers on my home network. i set up one computer just fine, and got internet and everything, but i turned on the second and they both came up with a few things: an ! point in the lower right, a "limited connectivity" warning on the LAN connection that when clicked on says that it can't renew the ip address...and a pop up error, that says there is a ip conflicted with another system on the network.
I don't know alot about networks, but i'm trying to learn....URG! it's very frustrating.

So do i need to talk to sbc and tell them i need to set up for more computers and get a different modem, or can i make this work?

Thanks

You need a router, not a switch.

The speedstream 5100b (5 LED modem) hands out a single DHCP lease. So the first computer that turns on connected to the switch will grab the lease. Other's that follow will run into ip conflictions. I recall seeing there is a way to use the 5100b as a router over at DSLreports, but there site is down or else i'd direct you. NO, sbc will not help configure the modem to support more than 1 computer. The best then can do is sell you the 2wire modem/router in place of the 5100b.

so can i just get a router...or do i need a new modem?

Yep, just get a router.

if i talk to sbc and get their other modem/router meant for multiple computers will my connection be better?
does sbc need to give me more ip address or is the package i signed up for good enough, just not the equipment?

The Router part of the Modem/Router combos "Sux".

SBC will be more than happy to sell you more IPs. If paying more money makes you happy Go a head.

Otherwise follow the advice above. You can find a Cable/DSL Router for less then $20. If to does not work the loss is not so tragic.

I found the link. How to use the 5100b MODEM on more than one computer.
As others suggested, I would invest in a router, no new modem needed.

Basically, you only get one public IP address from your ISP. When you hook up multiple systems on a switch or hub, only the first one powered on gets that IP address, and the other ones don't get any. What a router does is allows multiple systems to share that one public ip address. A switch/hub can't do that.
