Making direct physical connection: (PC to PC), (SWITCH-SWITCH), (SWITCH-HUB), (HUB-HUB), (ROUTER-ROUTER) with "category 5" (10/100Mbits) UTP cables. We use crossover cable connections. Here is the picture of the RJ-45 connector with the pin numbers, and below is the information which number should use which coloured wire:

CROSSOVER CONNECTION: PC-PC, PC-ROUTER, SWITCH-SWITCH, SWITCH-HUB, HUB-HUB, ROUTER-ROUTER

Making direct physical connection: (PC-HUB), (PC-SWITCH), (ROUTER-HUB), (ROUTER-SWITCH) with "category 5" (10/100Mbits) UTP cables. We use straight-through cable connections. Here is the picture of the RJ-45 connector with the pin numbers, and below is the information which number should use which coloured wire (there is no crossover of the wires in cable):

STRAIGHT-THROUGH CONNECTION: PC-SWITCH, PC-HUB, ROUTER-SWITCH, ROUTER-HUB

Software configuration of the Local Area Network.
-Subnet: for a small network (no more then 254 IP's) you can use 255.255.255.0 for larger network 255.255.0.0
-IP:
For subnet 255.255.255.0 you can use IP's from 192.168.0.1 to 192.168.0.254 (or 10.10.10.[1...254]... as long as only the last number is changing).
For subnet 255.255.0.0 you can change the last 2 numbers of the client IP's...

-GATEWAY: Simply the IP of the local server you get the internet from (it should be the ISP's server, but if you use, for example, home internet sharing server you should put this server's IP address)
-DHCP (Dynamic Host Configuration Protocol): If you have DHCP server in the network it will configure all of the above automaticly. That server broadcasts on a specific address to the network. You must choose the DHCP option for your computer to use that service.
