Network connection not detected

[koos147]

Hey

my pi isn't detecting the link status anymore
when i unplug the network cable the ligts are stil on and the OS see a 100mbit connection

also when the cable is connected there is still a link but no traffic
is this a known issue or is my pi dead?

regards
Mark

Model B , B+ or 2 ?
if you switch it on with no network lead connected what happens
does the USB and keyboard work

[koos147]

Hey

i am sorry it is a b+
the keyboard works fine (i have no mouse)
with no network the network leds are blinking (not so much since there is no data)
there is no different with or without the cable
the image i am currently trying is a raspbmc installation

Regards
Mark

i added a usb network card to the pi and booted
it now show 2 nic's connected but the external version is working

i saw the warrent is only one year so no luck on that side
now i have a nic that is bigger than my pi itself
if anybody has a idea how to bring the onboard nick back alive that would be great

cat /proc/cpuinfo

if it is a b+ then it is still in warranty as they where only introduced in July 2014 ?

if it is a B and the keyboard is working then the x1 crystal is fine and it still should work.

does dmesg say anything useful

i think you mean 2013

i found out that i was wrong about the model
i have a B and a B rev2 which i was thinking was the B+ since it had 512mb ram
but that didn't change the fact the nic is broken
i was looking for a small usb network adapter but it is half the price of a new raspberry
so i will replace it and hold this one as a wifi spare

Have you looked at a sharp physical shock, or heat treatment or resoldering the 25MHz crystal on the Pi with the non-functional NIC?

Bad advice. That only risks making things worse - the keyboard is working so the LAN/USB chip oscillator is working.

i just swaped them with a raspberry hidden after a cabinet so the big and ugly usb-network cable isn't visible
so i am happy
