Use a hub to connect 2 pc's to the cable modem. Why doesn't it work?
I am using a 10/100 8 port hub to connect 2 pcs directly to the internet.
The cable modem is plugged directly in port 1. The other 2 computers are plugged in to port 2 and 3. Only 1 pc is connecting to the internet.
Shouldn't the second PC automatically get assigned another IP address?
I can't ping anything off of my second computer. The same computer (laptop) connects fine at school. I checked the cables and they are all ok. I know the hub is ok because a few days ago I was using it on another LAN.
Any ideas or suggestions?
TIA

The hub won't assign the second computer a IP address, you need to do that manually, and to get that IP #, you have to call your ISP and they will give you a second IP #, an happily charge you for it as well.
What you need to get is a router, which you will assign your current IP address, and any computer that is hooked up to the router will be assigned an IP # by the router. Then you can surf the net with any computer using the 1 IP address your ISP gave you.
Anybody please correct me if I am wrong. Good Luck!

I understand that the hub will not assign an IP address. However is there not a server on the otherside that assigns IP Addresses? If so, why didn't it assign the second computer an IP address.
what assigns the IP address to the computer? The cable modem or is the IP address assigned to the Cable modem?
The problem is that I need to do this at a customer who also has the same company for a cable modem. He is also a Prudential Agent and wants to use his Laptop to connect to Prudential Intranet. I have Internet Connection Sharing running on a Win98 "serveR" at his house which works fine for all computers except his Prudential Laptop. When we connect his Prudential Laptop directly to the cable modem it connects to the Prudential Intranet, but if I try to connect using the "internal network" in his house, it times out.
Anyone have any experience with a similar situation? This is why I am wondering if a Linksys or similar router would even work.
Thanks for the quick reply you guys...

That "name" and the IP (if static) can be programmed into the router.
If the notebook needs to travel another network there are a couple of options. I think the easiest is still using a router. If the notebook already uses DHCP to connect to the office network then you don't need to change anything on the notebook, just make sure the router has the correct "cable" settings. If the notebook's office network uses static IP's and such, you can easily change the router's LAN IP Addressing to match what the notebook needs so that the NB doesn't need to be changed everytime it's moved.

Dude, get a router. Problem solved.
Buy.com has 4-port SMC routers which includes a print server (nice bonus) for like $70 (US).
I personally recommend Linksys for their simple interface and excellent support. My 4-port ran $89 (US).

Holy Crap! I ordered the router from Outpost last night at 10.30pm and for only $12.XX I chose overnight. I picked it up this morning at 10.30am!
That is the fastest package delivery I have ever gotten and that too for $12!

i agree with the router idea....that is what i am doing...the only way i have seen a hub work is if you make one computer work as a router and install two network cards
cable to cable modem
cable modem to nic1
nic1 to hub
hub to all

Agreed with above posts advising towards router...Using same lynsys here. Don't forget it also saves you money (added IP= mo'money usually)
Which one did you get?

I ended up geting the Linksys 4port..... plugged it into my lan and most everything configured itself. Lets hope it is this easy at the customers tomorrow.
Thanks for the suggestion guys... even if it doesn't work for the customer I suppose I will have to eat the cost and use it at home <wink>. Thats what I will tell the wife anyway.... he he

Ok i'm sure someone else has posted something to the effect of what i'm about to say but i dont have time to read through all of them to see if anyone actually put in the right answer to this (one that makes sence to anyone that is)
First of all you have 1 IP address from your ISP and unless you pay for more that is all you will get. This IP address is for lack of a better term at the moment your "External" IP address, or your internet IP address. Now what needs to happen can be done one of 2 ways, i'll explain the easiest first. A hub simply conects pc's to each other (or in some cases other hubs), a hub is NOT capable of "routing" traffic in such a way that requests out to the internet would get where they need to be, this is where a router comes into play, now this router can be setup to auto asign "Internal" ip addresses to any system that conects into that is set to auto grab an ip address. Now this router has an IP address of its own as well, and when a computer conects in to get an IP address the router also asigns that computer a gateway IP address (which would be the IP address of the router) the cable/dsl etc then plugs into the routers WAN port (may be labled differently on some routers) and then the router can be setup to access the cable
once all this is done abra ca dabra you have a working boardband internet conection sharing setup
The next way is to make one of your pc's the "router" if you have Windows 2000 (or even Win98 SE with ICS) but you must have 2 NIC's in the one machine (one to the cable/dsl modem, and one to your network) then configure ICS and setup each additional machine on your network to look at that machine for internet, i dont prefere this method myself as multiple nic's in a single system first of all usually isnt a supported setup by the ISP, and second can sometimes cause conflicts
hope this helps clear things up

good thing you went with a router, even if you got the two up with a hub your security would be crappy/bothersome!
I personally use a proxy server w/checkpoint firewall but I have a pretty good network to protect. The only downside to a proxy is a higher ping on games but owell...

I currently use the Linksys 4port router so I can just plug my laptop in at home without having to unplug the cable from my computer, turn off the cable modem and reboot. It works great. I notice only a very tiny dropoff in speed. The Linksys is great the way it configures almost everything automatically. The only thing that would be better would be if I could use the two vacant places on the router as a hub, or somehow communicate thru the router to the other computer. Sort of a combo hub and router. Of course if it could be done thru one net card... WOW
