A few days ago my Raspberry Pi 2 was working perfectly, but today I turned it on and it said "no wired connection" even though my ethernet cable is connected. I tried various things such as rebooting the router and restarting the Raspberry Pi but none of that helped me.

    Do you see ethernet lights on port ? Aug 13 '15 at 5:23
  • A bit more information is needed here, like what steps have you taken to troubleshoot. Also: I say this 200x a day here, is your powersource up to the task? (5V 2A, with a not-too-long USB cable)

  • Try and change the cable, plug it direct into the router with a cable that is working, not the same one (maybe you dog/cat/chinchila chomped it) - Reboot your routers/modems too. It should work

Well if we want to go bug hunting try eliminating possibilities;

  1. Save your image, reinstall Raspbian and check if your connection works now.


Problem about your Software, ask yourself if you've installed or uninstalled anything just before your last reboot.


  1. Problem about your Hardware or Internet connection, try another cable, does it work now?


Get a new cable.


You might have fried your Pi, from this on it gets more tricky to find out what happened.

  • Good problem solving steps :) most likley software issue, or modem DHCP is hung up. Some reboot somewhere will fix it or cable issue...
