House owner is purchasing a new PC that will be using a wirless modem. He has been using a cable modem through Comcast, as have I using the phone jack in the back of my PowerMac G5. What do I need to do to prepare myself for this conversion?

Mac Pro, Mac OS X (10.5.8)

    Hi, is this a G5 or a Mac Pro, two similar looking quite different Beasts!?


    Likely you have an Airport/Wifi card installed already.


    Make a New Location, Using network locations in Mac OS X ...




    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.



    10.5.x/10.6.x/10.7.x instructions...


    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.


    The interface that connects to the Internet should be dragged to the top of the list.


    Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

    it was called an "Intel G5" when I purchased it 4 years ago).

    We're not remembering someting correctly, never was an Intel G5... mutually exclusive... G5s were IBM CPUs.


    So we know more about it...


    At the Apple Icon at top left>About this Mac, then click on More Info, then click on Hardware> and report this upto but not including the Serial#...

    I DO NOT have an AirPort/WiFi card installed.

    4 years ago you should, perhaps it's dead?


    Thick Walls are a problem for Wifi.

    Ok great, here's the specks on that great Power Mac...


    going through several walls and spanning a few rooms is going to make a wireless connection very difficult (or near impossible)?

    Depends on the walls, are they concrete, Brick, wood, plaster, etc.?


    You could alieviate soime of the problems, not sure how much, but an improvement for sure, by using USB Wifi dongles & say 10' USB extention cords to extend closer & generally placed higher in the room:s)...
