Wireless networking for two computers

  anniesboy68 15:46 05 Jan 2004

I have a cptr with a Prism 11g wirless adaptor card. What do I need to connect to another computer in the same room running XP but with USB1.And will the second computer be able to access my NTL cable broadband connection, please

Both computers need a wireless network card, either PCI (for desktop), PCMCIA (for laptop) or USB (both). As for sharing an NTL broadband cable line, I don't know.

NTL provide the cable modem which you can plug into any Broadband router with an ethernet WAN port.

If you want to connect the other machine to the internet wirelessly, without the need to have the main pc switched on all the time you will need a router and a wireless PCI card.

The NTL box will plug into the WAN port of the WIFI router, then one computer will plug into the router through a network card. The wireless router can connect to the other machine through the wireless card.

Check that the router will allow you to change the mac address (NTL are a bit vicious on this one) of the wan side. If it doesn't you could give the router a name and this will save having to spoof the MAC address.

Hmm, spikeychris....looks a bit complicated. I am totally usless on this sort of thing..what is WAN? What is WIFI, and what is MAC.? As I see it now [forgetting NTL connection for now] I need another wireless network card for the second computer and a wireless router.. Right?

If your wireless router is close to one of your computers why not connect to the router with an ethernet cable and just have a wireless card on the other machine. This will save you around £40. You don't need wirelss if one machine is anchored next to the router all the time

I'm out of my depth here, will wait and consult a friend methinks. Thanks for the replys however.

That's what we're here for.

WAN = Wide Area Network as opposed to

LAN = Local Area Network.

MAC address = a unique 12-digit identification number, assigned to all networking hardware for identification. No two hardware devices have the same MAC address on a network.

Forget about all that for the moment though, because you should be able to have broadband connection sharing without having to bother about any of it.

Why don't you get an NTL Actiontec Home Gateway wireless bundle for £99.00 and have it all set up in a very short time? The bundle includes a wireless router, a USB adapter for your computer, and the necessary software. Your existing wireless network card should be OK.

Set up the router - the instructions are pretty easy to follow, and connect the USB adapter to the second PC. You should now be able to share the broadband connection between the two machines, and it isn't necessary for one of them to be on when you want to use the Internet on the other one.

What does 'WiFi' mean?

It's the logo of WECA (Wireless Ethernet Compatibility Alliance) that is a group of companies founded by 3Com, Cisco, Intersil, Lucent, Nokia and Symbol whose aim is to provide a marketing and interoperability alliance for ieee 802.11b.The WiFi logo stands for 'Wireless Fidelity' and demonstrates this compliance.

Forum Editor. Thank you, it is becomming a lot clearer now. The wireless Adaptor connects by USB to the second computer, USB1 mind, not 2.However, how does the "router" recieve the signal from the host computer, ie the one connected on NTL cable.By means of my existing wireless networking card I would assume. Is that correct. And once again, please excuse my very limited knowlege on this. And I see on the website you included, files can be transferred also. If I have understood that the foregoing is correct I shall be spending again.

from a host computer, because you don't need one. The Wireless Router simply connects to your existing broadband connection and transmits it wirelessly to any wireless network adapter that's in range.

That's why any computer can use the internet without any other machine being on - the router is on, and it does the work.

Don't apologise for your limited knowledge - nobody knows how to do this the first time around. Within a short time you'll be completely at home with your new network, and you'll be reassuring other beginners here, in the forum, when they set one up for the first time.

Good luck, and don't hesitate to come back for more help/advice if you need it.
