that your mac have an airport card. If you already have it, then you can connect using wireless...
You need airport extreme OR airport express (one or the other, unless you need addtional need)
If your modem have a router, then you can connect your Airport extreme or airport express to one of the port, and your pc to the other empty port.
I have some questions about wireless internet for a Macintosh Powerbook G4 using a cable modem and AirPort Extreme and/or Express. My regular computer I use is a Windows XP Hewlett-Packard HP Pavilion 6830 computer with a Scientific-Atlanta DPC2100 cable modem, with Internet supplied by Cox Communications of Northern Virginia. My Powerbook G4 is from 2005 and has OS 10 on it (unsure what the exact version is). OS 9 has not been installed on it.
My questions are these:
1) This first question isn't a wireless question, but if I hook up my Mac PowerBook G4 to the cable modem via a USB cable, could I use my Mac for internet right there? Is my Mac already Internet-ready? (It has the AirPort card already installed, as I understand it.) How do I get the existing cable modem to work with my Powerbook?
2) If I bought a wireless cable modem such as the Motorola SBG900, would I still need AirPort Express or Extreme to get a wireless Internet connection on my Mac? Or would I have to get AirPort irregardless of whatever modem I get?
3) Would I be correct in saying that AirPort Extreme allows one to wirelessly connect to the Internet from greater distances than Express?
4) Can one use just AirPort Extreme with the cable modem, or is Extreme best used with Express?
5) This is a general question. Why is it difficult to find reviews and good ratings on several sites for cable modems? I'm trying to compare ratings across different sites, but the results are piecemeal. To give credit, I do check out this site and it is helpful, but overall it's difficult to locate solid, rated info across the web.
6) Just remembered--we tried to have the current cable modem (Sci-Atl DPC2100) be recognized by the Powerbook, but apparently the installation disk for the cable modem needs OS9. Should I install OS9 on my Powerbook? There is another disk for installation (but not for the modem) that says that it is for OS9 and higher. Should that be used?
Sorry for the amount of questions, but I really appreciate any help that you can provide by answering these questions. Thanks!
