To connect 2 pcs is simple u can do by making a cross/by pass cable. the method is to either go to the cable shop and ask to make a cross cable, which is done by connecting 2 rj 45 connectors, with a cat-5 cable. u must make sure that when u hold the rj connector face up(where u can see the connecting wires) from left is no1(there are 4 twisted pairs) connect 1 to 3, 2 to 6, rest is straight, i.e. 4 to 4, 5 to 5 7 to 7 8 to 8. please mark it as peer to peer cross cable. in case of more than 2 pcs u have to connect through the hub, which is expexsive compared to the lan card. lan card is rs 300/= then cable is rs 9/m(for 10m it is rs 90/=) and hub min 6 port, is rs 1500/= parambir
