What do I need to be wireless?

Assuming that your modem is a cable or dsl modem that is able to connect by ethernet, you will need a wireless router and wireless network adapter in your computer.

First you need a broadband internet connection (cable or dsl) with a cable or dsl modem that has the capability of connecting by ethernet (cable or dsl modems that can only connect by USB will not work).

Next you will need a wireless router. Wireless routers have 4 ports that will connection of up to 4 computers by wired ethernet. It would be preferable that you connect any computers in the same room as the cable/dsl modem and router by wired ethernet. In that case any computer that is located within easy reach of the router and modem will only need an ethernet network card.

Then, any computer you want to connect by wireless will need a wireless network card. If you are not sure whether or not your computers have wireless network cards, check Device Manger under Network Adapters.

There is really no need to get a wireless router that advertises high speed, unless you are frequently transferring large files between computers on the local network. The standard 802.11g speed routers are much faster than a cable or dsl internet connection, so the higher speed would be wasted with the higher speed routers.

Once your network is setup, you can share any printer connected to any computer on the network, so long as the computer to which it is attached and the printer are powered on.

Yes it is a cable modem.  Not sure what ethernet is.

Ethernet is the type of connection the modem will make to the router, rather than USB.
