Q: Ethernet not working

On April 2nd I downloaded mail from my ISP mail server using Mac Mail. A couple of days later while downloading mail in Mac Mail all I get are the circles with the triangle. Safari will not connect. I worked with my ISP yesterday, and they think I have a bad cable(s). Today I connected a known good Ethernet cable from the computer to the DSL modem with the same results of no connection with Safari. I am therefore thinking something is wrong with the built in Ethernet.  In an iMac PPC G4 flat screen, is Ethernet on a card or part of a chip? Any idea on the cost to fix the problem? There is an Apple Store close to where I live.

 

Once all the cables are reconnected Wi-Fi does work. This leads me to believe that the problem is in the computer, and not the cables.

    Do you have anything else you can connect to DSL modem's Ethernet port, to test it?  Maybe that port is bad, not your iMac's port. 

    Once all the cables are reconnected Wi-Fi does work.

    Does this iMac G4 also have AirPort capability, or are you testing the WiFi with another computer/device?

     

    It may be helpful to know some more details.  What specific model is this iMac G4?  You can look at this list to find your specific model

    What version of Mac OS X does it run?

    is Ethernet on a card or part of a chip?

     

    I believe the Ethernet components are part of the motherboard.  It is probably not worth the cost of repair, if it is broken.

     

    You can try some basic troubleshooting steps...

     

    First, make sure you have completely shut down (powered OFF) the iMac and started it back up, since this problem occurred.

     

    Second, try resetting PRAM

    Third, try resetting PMU (power management)

    When you do this, if the iMac had been plugged into an old (or overcrowded) power strip (surge suppressor), connect it directly to a wall outlet.
