Some have an older iMac or G4 Powerbook, it can still do some horse-work when you like. You can use that machine for some older administration and/or other older software, but you can also connect that Mac with a UTP-cable into your network and use it also as a WIFI access point (Airport) for all your other WIFI-running PC's, iPad.s and PDA's. Just follow these steps and it's simply done. And your older Mac get's a second life.

To make your Mac a WiFi access point, follow these steps on the Mac that has the Internet connection: Select System Preferences from the Apple menu, click the Sharing icon, and then click the Internet button. From the Share Your Connection From popup menu, select the way this computer is connected to the Internet: typically Ethernet, Modem, or Bluetooth.

In the To Computers Using section, select the AirPort check box. Click the AirPort Options button and assign your new network a name. Turn on encryption if you like, enter a password, and click OK. Back in the Sharing pane, click the Start button in the Internet Sharing section.

Your other computers should now see your new WiFi network. When you no longer want your Mac to serve as an access point, go back to the System Preferences Sharing pane and click the Stop button in the Internet Sharing section.

Some will think you get troubles and no access with sleeping of that Mac, but just open the "energy saver" preference and select to wake up that Mac when an internet-approach comes in.
