Help connecting two wireless PCs to one router arial... can it bedone?

Question

Here's what I have:

Router: 54Mbps 4 Port Wireless Cable/DSL Broadband AP Router 802.11g/b 4 ports
Model No: SWBARR-5400

1 Wired PC in study
1 Wireless Laptop in Loung
1 PC in bedroom (not connected)

ok, please go easy on me :)

I have the main computer connected via ethernet cable (virgin modem to router then router to pc) I understand this is called "hardWired" ? then in the lounge-room my wife has her wireless laptop. both PC and Laptop work great, both connect to internet and both have full access to each others machine. NOW, here's the problem ;)
My Eldest daughter as got a PC in her bedroom, I do not want to run a cable all up the stairs etc but our router only as one wireless arial? whatcan I do?

Someone said that I can stick a ethernet arial into slot 2
(or 3, 4) and make another wireless connection. is that right? obviously, I'll need to purchase a wireless dongle or something for the daughter yes? OR can two wireless PCs run from one router arial?

Many Thanks
Sean

Answer 1

Yes you can run 2 wireless PC's from one router. you don't need another antenna. If the other pc is already wireless you don't need anything. If it isn't you can either get a USB wireless receiver or a PCI Card wireless receiver. USB will be the easiest install for the average user.

Answer 2

Your wireless antenna / arial on the router can support many many connections unlike the "hardwire" plugs so all you need is an adapter in the computer upstairs that will wireless connect to your router.

You dont add anything additional to the router it will work the same on the other computer as it does with your exisiting laptop.

Answer 3

You need a wireless interface for the PC. You could choose between a Wireless PCI card like this:

or a Wireless USB adapter like this:

They connect to only one PC.

I prefer the USB type because you could move the antenna portion w/in a 1 meter radius for best signal reception/transmission.
