Home network

Yes.

In fact, even though it would usually make more sense to share the internet with a wireless modem/router, I can see scenarios where that may not be a possibility.

In that case you could even get a wireless card or USB adapter for each system and run them in ad-hoc mode. That way you could drop the need for a base station (router).

Seriously, test a USB adapter on your system before buying it. Those things gives bluescreens like hell and are very unstable. Get a card if you can.

Of course it isn't any better to run ME with USB adapters.

whats a ad-hoc mode?

I just happened to be at wikipedia when I read this, so that's where I searched. :)

Is this for high speed internet or 56k?

optimum cable

i just recieved 802.11B CABLE/DSL WIRELESS ROUTER from a friend who didnt need it anymore,what else would i need other than this?

If you will still connect your main computer with wire, you need 1 additional network cable for that. Then you need wireless network card or USB adapter for each pc connected wirelessly..

You connect the existing cable to the WAN side of the router. Then connect the new cable between the LAN side of the router and the main computer if that's how you want to connect it.

Even if you are going to connect everything wirelessly, you can use the existing cable between the computer and the LAN side of the router for the initial configuration if you have problems setting up the wireless network.

what would u suggets is better the card or a usb?

I've seen results equally as good (or bad) with both.

Plenty of PCI slots and want to keep any USB ports free? Go for the card.

Short of PCI slots or not 100% confident about fitting a card? Go for USB.
