No network lights

plone

The Raspberry Pi boots but the network lights do not light up!

 

Router is fine, ethernet cable is working -- problem that there is no connection.

 

Any suggestions?

  • DId you try running:

    sudo raspi-config

    in order to configure your ethernet connection? Because if you're connection has a password or needs other configuration, you may want to try that, otherwise you may have a faulty Pi, in which case you should ask for a replacement.

    Are your USB devices (keyboard, mouse) working OK?  They use the same USB/LAN chip as Ethernet, so it would be good to know if the USB chip is working at all.

     

    Check for known problems at the RasPi Troubleshooting Wiki: http://elinux.org/R-Pi_Troubleshooting#Networking

     

    The most common problem with RasPi is inadequate power.  If you have voltmeter or multimeter, check that your 5V power is OK: http://elinux.org/R-Pi_Troubleshooting#Troubleshooting_power_problems

    Hi John:

     

    USB devices work just fine. Tried both hardwired usb mouse and keyboard and wireless Logitech mouse and keyboard both work fine.

     

    TP1 is 5.02 volts.

     

    Linux boots to command line but when the eth0 driver probes the connection it finds nothing.

     

    All my ethernet cables work with other computers just fine.

     

    I suspect that the female ethernet connector on the board maybe defective.

    Yes, it sounds like a bad Ethernet jack.  Could also be a missing or bad passive component, bad Ethernet circuitry in the USB/LAN chip, or a bad PC board or solder connection.  Just for fun, take a look under a strong magnifier and look for solder bridges and Ethernet jack pins that haven't been soldered properly.  Conceivably the vendor could have installed the wrong Ethernet MagJack, though you'd think that would have been caught with factory testing.  In any of these cases, sounds like time for RMA.

     

    The problem could also be a bad OS image, but I would think that's unlikely since everything else works.
