Setting up a New Connection

  Thomo1 22:11 01 Oct 2005

I am just about to buy a lap-top and amongst its other uses i want to be able to connect wirelessly to the net on the laptop using my main computers broadband connection.

I want to be able to have the freedom of using the net around the house without sitting in my living room watching the plain awful programs that my mother and girlfriend watch!!!!

What bits of kit do i need in order to set up a wireless connection on the laptop from my main pc?

For both my pc and a laptop?

To create a wireless network you need:
1. Two or more computers, each with a wireless network adapter installed. To make it easy you can buy USB adapters that simply plug into a USB port, but if you're not averse to opening a computer's case you can install a PCI card adapter for slight better performance. A laptop needs a PCMCIA card adapter - if it doesn't already have wireless network access built in.
2. A wireless router. This enables one computer to see, and access files on another machine, and you can transfer files between machines. If you buy a router with a built-in ADSL modem you can share a broadband internet connection between the networked computers. Alternatively, you can use a non-modem-equipped router with an existing Ethernet broadband modem.

Is that what you wanted to know?

I think that answers my question doesnt it? There is nothing else that i will need?

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

1) Install a Wireless Network Adapter in each PC and create an “Ad Hoc” Wireless Network. This is a network in which the two PCs talk directly with one another, rather than via a Wireless Access Point. “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, it automatically configures the Local Area Connection with the IP address and subnet mask However, as you will be using a WiFi adapter, you want this address to be allocated to it, rather than a “wired” Ethernet adapter if you have one fitted, so the Local Area Connection should be disabled before setting up “Internet Connection Sharing”. 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. The "Client" PC's Local Area Connection should be set to get its IP address automatically, which it does by DHCP from the "Host" PC.

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”. This is an ”Infrastructure” wireless network because the connected PCs communicate via the router’s Wireless Access Point. Again, a wireless adapter is installed in any PC that needs to connect wirelessly, but often the main PC is close enough to the router for it to use a “wired” connection with only the remote PC connecting wirelessly

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

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