Why does Airport not work with my home WiFi on my PowerBook G4?

Wayne brunson November 11, 2011

My PowerBook G4 OS X 10.4.11 is not connecting through WiFi at home. I’m using actiontec. WiFi signal is locked. It works through LAN cable and the Airport works at McDonald’s.

    First I suggest to find out which Wireless standard your AirPort card supports. Open System Profiler and go to "Network > AirPort card".
    /Applications/Utilities/System profiler.app
    I don't have an older system at hand but the entry should be called "PHY modes" and there the value should be something like "802.11 b/g".

    Next make sure that your actiontec Router/AP supports such devices. For example it shouldn't be set to "G-only" mode or similar, also it has to be 2,4GHz because the old AirPort cards do not support 5GHz Wi-Fi.

    I also suggest to set the wireless encryption to either WPA or WEP (first one being the better choice) because most older Macs do not support the WPA2 standard.
