Hi guys
I have a big problem and I hope that you guys will help me out of it.

I have 2 PCs connected to a 4-port hub, and the hub is connected to the DSL modem to be able to access to the NET. Because it is a 4-port hub, so I have one free port, and I`m trying to connect another Laptop to the internet through that port. The Laptop recognizes the cable, but it appears to be a "limited or no connectivity", and I can not access to the NET using the Laptop. Why? While the other 2 PCs are accessing normally. What do I have to configure? please help me out of this. Thanks in advance !

hub or router? How many IP addresses does your ISP give you?

With a simple hub (or switch), your ISP needs to allocate you multiple IP addresses.

Otherwise, you need to buy a router. A router only needs a single public IP address, and all your PCs are on LAN IP addresses routed through the device.

I hope you are running Windows XP on the laptop.
Check again the dsl modem and laptop network connection settings. There is a big chance to miss out some parameters to give there.
If you be sure to configure all correctly and if you are running XP with SP2 then you may need this
patch to fix a bug in SP2 for this error.

Why do you hope he's running Windows XP? What does having Windows XP have to do with DHCP?

Axe: Sorry for my limited knowledge, but I dont know what a router is, but I guess what I`m using is a HUB because it is written there. And again sorry for my limited knowledge, I dont know how many IP my ISP gives me, and even where to figure it out. And I think it has to be posible to connect it because I already have 2 PCs connected and accessing the NET (unfortunately it was not me who set them up :( ) I have been trying to connect PCs before but I never got it :oops: . Can you please show me how to make it? I`ll really appreciate your patience.

By the way, pramitroy, I am running winXP SP2 on my laptop.

Have you tried unpluggin one of the PCs and plug in the laptop, if it works, then your ISP only allows you to connect two computers to the net.

Can you give us your hub model? I know some laptops don't support 100mbs and maybe your hub does not have speed negotiation

So I can recommend a store from which you can ask questions and purchase a router :)

If you were in the US, I would suggest BestBuy or Circuit City. If you were in the UK, I'd suggest Dixons or Comet. In Panama, I've no idea.

Basically, a hub just networks. A router acts as a gateway between your local network (your 2PCs + Laptop) and the outside world (the internet).

If your ISP doesn't provide you with 3 separate IP addresses (one for each of your PCs), then you need to use a router - which your local computer store would be able to tell you about the various models available to you.

On the two PC's connnected to the network do this:

Open up control panel
open up network connections
right click your connection and select properties
double click Internet Protocol (TCP/IP)
Write down the settings

Right click My Computer
Select Properties
Click on Computer Name tab
write down workgroup name

Now on your laptop make sure that it has the same workgroup name and same TCP/IP settings unless the IP is set statically, you can't have two computers with same IP on a network.

I think the problem is no my ISP because I even tried to disconnect 1 of the 2 PCs to connect my laptop, but nothing better. I think it is a problem of some configuration or some conflict.
Thanks alot for your time!!!
