Setting up a wireless connection

  Mr Mark Nolan 12:37 01 Dec 2005

i currently have one computer but i will be getting my second computer very shortly as soon as i get paid and i want the internet on both PC's so i was just wondering what do i need to make a wireless connection and how much will it cost.

i thought all i would need is a router, ISP connection (obviously) lol and a second computer but i dont know if i need anything else?

any suggestions

You haven't said how you connect to the internet:

- Dialup with a 56kbps V.90/V.92 modem?

- ADSL broadband via the phone line?

- Cable broadband from NTL or Telewest?

Assuming broadband, my standard "blurb" on Wireless Networking:

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”. 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. 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...etc”.

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.

<<< i was just wondering what do i need to make a wireless connection and how much will it cost. >>>

Wireless Network Adapter (PCI or USB) for each PC - £20/£25 each

Wireless Broadband Router for use with "Cable Broadband" (NTL/Telewest) - about £50

Combined "Wireless Router/ADSL Modem" for use with ADSL broadband - about £70

NOTE: If you currently use a USB modem for ADSL broadband, the modem is not suitable for use with a router. You need to replace it with a combined router and ADSL modem.
