Raspberry Pi Ethernet Problem

Former Member
Former Member over 12 years ago

Whenever I turn my Raspberry Pi on, the three network lights just blink and it can't connect to the internet. I have checked all network items and they do work so it comes down to the Raspberry Pi.  Is there something physicaly wrong with the board itself?

 

It is Model B and I have Wheezy installed on the SD card if that helps or makes a difference at all.

    Hi,

     

    I had the same problem. I was trying to connect to the internet for the first time. I did the same things. Set static address, restarted the pi. Finally the 'ifdown' and 'ifup' did the trick. I had to use "sudo ifdown eth0". Without the sudo I got a permission error.

     

    Thanks you all for the help.

    I also am having problems with a Raspberry Pi (a B+). Did have a connection with a wifi adaptor but that broke and will be going back. Tried plugging in an ethernet cable and the hub appears to be seeing the Pi but the Pi says that there is no internet connection. Tried 'sudo ifdown eth0' followed by 'sudo ifup eth0' and got a series of DHCPDISCOVER messages followed by 'No DHCPOFFERS received'. ifconfig shows no internet address against eth0.

     

    Any help would be really appreciated.

    I'd check a few basics:

    1. Eliminate the hub (surprised these are still available) and plug directly into your home router's switch ports (usually there are about 4 ports on the LAN side, plug into one of them)

    2. Try a different Ethernet cable, in case it is faulty marginally and allows the link to come up but not communicate

    3. Turn off/on your router in case it really can't assign an IP address for some reason (could be a faulty router)

    Hi shabaz. Not sure if I mean hub or router but whichever, you were right, that was the cause of my problem. Realised this shortly after placing my message when everything else in the house lost internet connection.

     

    Turning hub/router on and off (with the 30 second pause) fixed the problem.

     

    Thanks for your help.
