Hi when I boot up my Raspberry Pi it stays connected for about 2 minutes but suddenly disconnects. It does not reconnect unless I reboot it. Please help.

  • note if you don't get an answer here there is a SE for the pi.... http://raspberrypi.stackexchange.com/ – Tyson Nov 06 '14 at 04:52
  • Is the light on the cable jack going out when this happens? If not, does the output of ifconfig change? What is the output? Does ifup eth# fix it (where # is the interface number which is failing)? If all else fails check lspci -v to see if the card itself is disappearing. – krowe Nov 06 '14 at 05:12
  • Is it static IP or dynamic IP for the Raspberry Pi? Post the output of ifconfig command when it is connected and when it is disconnected. Post the /etc/network/interfaces file of the Raspberry Pi. – Jay Nov 06 '14 at 05:38

Most networking problems with Raspberry Pi's are solved by using a different power supply.

Especially the model B, which can draw significantly over the 700 mA which many power supplies provide. Connecting all USB devices to a hub which has a separate power supply can also help matters.

This completely solved my issues after months of continuous disconnections (every few seconds sometimes)

sudo ethtool --set-eee eth0 eee off

  • Welcome to SuperUser! Could you please write something on how this solves the problem? Just posting uncommented commands is not a good style for answers. – DarkDiamond Aug 29 '22 at 09:56
