New broadband connection and 2 PCs

I've just ordered 1 MB ASDL broadband connection and would like to access Internet from 2 PCs. One PC has ethernet card (unused as yet) but the other hasn't). ISP (Tiscali) informs me that I need to buy a wireless ASDL router and that "any would do". I assumed this would be a device in addition to the ASDL modem but having looked on the Internet to buy one I am now wondering if this is instead of the bundled ASDL modem. If this device is connected to the computer which connected to the phone line what do I need for the other PC to connect. Both PCs running XP Professional. Package arriving in about 10 days and I would like to be prepared.

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. 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”.


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.

As above, you don't NEED to use a router, you can connect the two PCs directly and "share" the host's internet connection. The host PC, of course, needs to be online. Also, if you do buy a router, it doesn't need to be a "wireless" model, you can have a wired network.

<<<I assumed this would be a device in addition to the ASDL modem but having looked on the Internet to buy one I am now wondering if this is instead of the bundled ASDL modem>>>

ISPs supply USB ADSL modems because this is the cheapest option for them. A USB modem cannot be used with a router and so it is replaced by a combined "Router/ADSL Modem". If using a router, it is essential that you get one that is both a router and ADSL modem combined.

<<<If this device is connected to the computer which connected to the phone line what do I need for the other PC to connect>>>

Routers, whether "wired" or "wireless" models, normally have four LAN (Local Area Network) ethernet ports, so both PCs would connect directly to the router.

Thankyou mgmcc - I now know that the ASDL modem that is supplied FOC is defunct and I have to supply my own. Is there a choice as to the connection type - by which I mean is there an alternative to USB connection for the router/modem on the host? As for the rest - I only have a vague understanding.

Perhaps I should have provided more detail - the two PCs are in different areas of the house and therefore hardwired connections (which I presume Ethernet requires) is a bit of a logistics nightmare. People blithly talk about it all being simple with "wireless" connections. So I still am unclear how I achieve this on the client - what do I need to buy? I'm not bothered about file or printer sharing I just want to be able to access the Internet from both PCs (which I do at the moment with dial-up connections). Any help/education greatly appreciated.

There are three types of ADSL modem - USB connected Modems, Ethernet connected Modems and Internal PCI card Modems, but these are NOT wireless options.

If you want a "wireless" solution, then you need a combined wireless "Router/ADSL Modem". These provide the option for you to connect either by ethernet cable or wirelessly.

In addition to the router, the PCs that are going to connect to it wirelessly need to have a "Wireless Network Adapter" installed. For a desktop, this would be either USB or internal PCI; for a laptop either USB or PCMCIA. If the router is to be located close to one of te PCs, that PC can use a wired connection so that only the remote PC needs the wireless adapter.
