ADSL Router Sharing Internet Connection Using HUB

filipino · January 9th, 2005, 10:40 PM

My cousin is asking me how to setup internet connection sharing using a ADSL Router and A network HUB, he has successfully shared file etc. but when he tried to share internet connection only one computer can be connected on the internet and the other one can’t cause he said something about IP address being use, I have no experience with ADSL Router through a Network HUB. Is there anyway around this? I mean to successfully shared internet connection using ADSL router and a Network HUB? Or do he need to purchased additional IP Address at his Internet Service Provider?

Thanks in Advance!

The modem should go into the routers WAN port and from there the hub should be connected to the routers LAN port. If he really does have a router and a seperate hub/switch then thats all there should be to do,

If it is an "ADSL router," does it not have multiple ports on it to connect other PCs? Why is he using the hub?

Hubs are "dumb" devices, they do not assign IP addresses like a router or switch. Any IP address assigned from the modem is being "sent" to all the PCs connected to the hub. Only one PC can use a particular IP address.

If he has a modem/router that can assign multiple IP address on the 192.168.*.* (inside his home network) then he can manually assign those assigned IP addresses (and subnet masks) to his PCs. They will each then have a unique IP address even though he is using a hub.

Why not just get a router? plug the modem into the router. It takes the single IP address assigned by the provider, then uses NAT to assign unique private 192.168.*.* addresses to each of the home networked PCs. Every PC will then connect to the router, whi8ch connects to the modem.

hi jmichna his ADSL Router only has 1 port, i think he dont like the idea of spending out some money to get a adsl router with multiple port

filipino,
While browsing one of my fav forums over at www.dslreports.com I ran across this reference. I thought it might be of interest to you...

So... Where does it route to/from? Itself?

A router that requires a hub? That's a waste of money.

I think filipino means an aDSL modem... but apparently some (like the 5100B) have the ability to assign multiple IP addresses on the home (LAN) side of the network, so you could get by with a cheap $10 4-port (dumb) hub.

It's not a waste of money, all depends on what you need. If you already have a network and just want to add a router, you used to be able to get the single port ones for about $29 when the others were 59ish.

I see. So in reality it's a modem with a router built in. Because if you get multiple IPs from the provider, then you would need a switch.

Why would you want to add a single port router to an existing network?
