connecting 2 pcs again

  slipned 21:57 29 Dec 2005

Hi all.
I've got a pc that is connected to a ntl broadband modem...i want to connect a second pc through a wireless connection. does the primary pc have to be actually switched on for the client pc to connect to the internet... or will the modem automatically connect once obviously the correct network cards are set up?
just wondering because i connected 2 pcs years ago through 56k modem and the primary pc had to be switched on..
thanks for all your help in advance

I think your 'ntl' will have to be a wireless router for you to go wireless with your 2nd computer, then it will not matter which computer is on.

You'll need a wireless router for cable broadband, you don't need the host pc to be on all the time. Here is a guide.

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. 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.

so if number 2 is the preferred option.. is this correct... I only need a network card in the client pc not the host...and i'd have to ditch my broadband modem for a router or do i keep my modem and somehow wire the modem and router together... again the host computer will not have to be physically switched on to receive an internet connection..
kind regards

<<< I only need a network card in the client pc not the host. >>>

When you use a router, there is no "Host" and no "Client", all computers connect directly to the router and have an equal status in the network. If one computer is located close to the router, it can connect by ethernet cable with only the "remote" computer connecting wirelessly and requiring a Wireless Network Adapter. Any computer can connect by ethernet cable and any computer (with a Wireless Adapter) can connect wirelessly.

<<< i'd have to ditch my broadband modem for a router or do i keep my modem and somehow wire the modem and router together >>>

No, with CABLE BROADBAND, you must retain the supplied modem and use a "stand-alone" router, often described as a "Cable/DSL Router", which has an ethernet WAN port (Wide Area Network - Internet) to connect to the Cable Modem. Don't confuse the reference to DSL with combined "Router/ADSL Modems" which are only suitable for use with ADSL broadband delivered via the phone line.

<<< again the host computer will not have to be physically switched on to receive an internet connection. >>>

With a router, each computer has internet access quite independently of the other. You can boot and be online with whichever computer you want.
