Ethernet port turned off after few minutes

Former Member

I am using 5V 1300mA adapter (http://www.skross.com/product/en/15/USB-Charger/56/World-USB-Charger.html) to power my Pi and another cheaper adapter that gives 5V 800mA.

 

The SD card is KINGSTON 16GB 100X SD10-HC.

 

I plugged in my Ethernet cable into the port and booted off Debian image from http://downloads.raspberrypi.org/images/debian/6/debian6-19-04-2012/debian6-19-04-2012.zip (SSH enabled). I am able to SSH into the Pi remotely and run basic commands, top, ps, ping. After about 15 minutes, the Ethernet LEDs just went off and my SSH session is gone too.

 

Checking the voltage at TP1 with my DMM it reads between 4.75 to 4.8V when the Ethernet is up and 4.9V when the Ethernet is down, i.e. the 3 LEDs marked FDX, LNK and 10M are off.

 

The same symptom is happening with both adapters. I have nothing else plugged into the Pi except the power and Ethernet cable.

 

Could this be another power problem? Anyone else seeing similar issue?

  • As someone else in possession of a Pi that seems to hang after a few minutes after booting I had initially considered that it might have a PSU issue but had ruled this out since I had tried a generic powered hub, a Belkin PSU rated at 5V 1A and a Nokia AC-10X rated at 5V 1200mA - all to no avail. WIth all three power PSUs the voltage across TP1 and TP2 seemed to be well within spec and other Pi owners seem to have had success with the likes of the Nokia charger.

     

    What I would really like to see is a definitive statement about the PSUs that are known to be good and/or official PSUs from Farnell that are guaranteed to work. As it is, I'm still unsure of whether or not my Pi woes are power-related and, if so, how I can really tell without the need to invest in bench supplies, test kit over and above a multimeter, etc.

     

    There's also a thread just started up at http://www.raspberrypi.org/phpBB3/viewtopic.php?f=6&t=5900 so you might want to add your voice about the issue over there so those of us suffering from the problem can compare notes.

    There is also speculation in the 'Hardware Flaws and Fixups' discussion on here regarding the power supplies.

     

    FWIW, I am using an HTC Desire charger, 5V 1amp and touch wood seems to be OK so far. I did have some booting problems where it just appeared dead, but updated to the latest debian image and that seemed to solve it for me (19th April Image I believe)
