I connected all 3 computers using a hub, but they cant get connected. But when i connect 1 computer to another, it's connected.
e.g: comp 1 to comp 2 = connected,
comp 2 to comp 3 = connected,
comp 1 to comp 3 = connected,
comp 1 to comp 2 and 3 [using a hub] = unplugged...
why?

The cable you use to successfully connect 2 computers together is called a crossover cable and will not work to connect a computer to a hub or router; you need a straight cable for hub connection.

More than 2 computers on an IP network requires a gateway/router. You can configure one of the computers to be a gateway (using ICS or other freebee software) but it would have to be on all of the time in order for the others to use the network.
A hub is just a switch and nothing more. A gateway is assigned a class C subnet, in which the gateway itself retains an IP address known to all others (like 192.168.0.1) . You could statically assign each computer a hard address if you want in the hosts file, but this becomes hard to manage. To avoid IP conflicts, gateway routers use a protocol called DHCP , in which IP addresses in the subnet are randomly assigned (leased) to any computer requesting it from the gateway. The gateway manages this lease list to ensure that each IP address is uniquely assigned.

You may need to install a network connection on the computers. ON PC - PC (2 PC's) its easy, because its always 1 to the other. But when there are three computers there is need for distinguishing computers, like an IP address is needed. You need to let the PC know there are 3 computers in the network and this should work.
Hope it helps!

First put one end of a straight cable in the open port of the switch or hub and the other end to the network card. You should have all the network drivers installed.

is it a reg hub? or a switch.
it might be the firewall. disable it.
check you router stats.
you may need to config your firewall their too.
look at your hub and it has an ip address
when u connect it type it in when you open the IE.
if you cant find you IP adress do
Start
Run
CMD
ipconfig

i think you are using cross cables....
use a straight cable to connect computers through a hub....
Thumb rule.....
two same layer device you will need a cross cable.....
two different leyer device you will need a straight cable....
PC to PC------same layer------cross cable
PC to HUB----different layer---straight cable
