a basic wired network setup -whats needed?

  mgmcc 08:03 10 Jun 2006

To create a wired network for Internet access and File/Printer sharing, you have essentially two options:

1) Install a Network Adapter in each PC (if not already installed) and connect them directly with a crossover CAT5 ethernet cable. “Internet Connection Sharing” is then enabled on the actual Internet connection in the “host” PC and the “client” PC will have Internet access provided the “host” is running and online.

When you enable “Internet Connection Sharing” on the Internet connection in the “host” PC, it automatically configures the Local Area Connection with the IP address 192.168.0.1 and subnet mask 255.255.255.0. The “client” PC’s Local Area Connection should be set to get its IP address automatically, which it does by DHCP from the “host”. Also, if you run the Zone Alarm firewall in your “host” PC, the Internet Zone Security level must be reduced from High to Medium or “ICS” traffic will be blocked.

To enable “Internet Connection Sharing” in Windows XP, open the Network Connections folder, right click the actual internet connection (modem connection), select Properties and then the Advanced tab. Tick the box “Allow other network users to connect through this computer’s Internet connection”.

2) The preferred option for connecting more than one computer is to use a broadband Router and, with ADSL, this should be a combined “Router/ADSL Modem”. All networked computers connect directly to the router with ‘straight-wired’ CAT5 ethernet cables.

With a router, it is the router which connects directly to the ISP and not one of the connected PCs. The router in turn allocates the IP addresses to the PCs, using one of the address ranges reserved for Local Area Networks, usually 192.168.xxx.xxx

Either of these options will additionally allow you to run File and/or Printer Sharing across the network.

If you are running software firewalls, the IP addresses of the networked PCs must be put into its "trusted" area to allow them to communicate with one another.

<<< how do the cables go? - Phone line into the modem (modem /router?) - short cable from the modem into the network socket on the back of PC No 1, and a L-o-n-g cable from the modem all the way through the house to the back of PC No 2. Then either run the supplied sofware, or the network setup wizard, from PC No 1. >>>

Yes, that's basically it. It does need to be a combined "Router & ADSL Modem".
