Wireless Networking for a small business

Would like to learn how to setup two computers, a printer, and DSL, with a wireless connection.

Thanks!

 

there are tons and tons of home networking tutorials on the web. Just do a search on google for detailed instructions.
However, you are going to need to buy a wireless dsl gateway. I'm a linksys fan myself, but there are many good companies making them out there. The gateways usually come with 4 ports for ethernet networking, in addition to the wireless access. You can connect the 2 computers either via a network interface card, or a wireless network card/device. The dsl goes into the WAN port on the gateway, and your computers go into the LAN ports, or connect via a wireless SSID. Once you get the gateway, there will be instructions included on how to do this.
As for the printer, you have to make sure your printer is network capable. If it is, once you have your LAN set up, you can share the printer with any computer connected to your network.
Good luck,
