RPI loose its IP address, not reason given.

Fri Feb 15, 2013 7:25 am

I have been experimenting this problem and now is getting very annoying as it is doing it very often. While I'm connected remotely to the the RPI using tightvncviewer suddenly it gets frozen and then I get a pop-up window saying there is not connection to the RPI. I then go to the physical RPI and issue the command ifconfig -a and the eth0 doesn't show any IP address. I then issue the command ' sudo ifconfig eth0 192.168.0.20 ' to give it back an IP and it takes it and I then can connect back with tightvncviewer in my PC, but after a little while the IP is drop and again not communication.

This is happening very often and sometimes even after rebooting the RPI it doesn't get any IP address so I have to do it manually with the ' sudo ifconfig .... ' so this doesn't look good.

I pulled the dmesg and I don't really see anything in it that shows a clue of why this is happening.

Any help to troubleshoot this problem would be appreciated!.

I am using the Wheeze from 12-16-2013 and I have it upgraded up to yesterday Feb 14th. yesterday there was an upgrade to the rasberrypi-bootloader as I saw it while it was upgrading. But this problem was happening even before this upgrade so I can not say it was because this upgrad.

the temperature of the core CPU with the command ' vcgencmd measure_temp ' shows as 42 Celsius degrees so I doubt it's because overheating.

this is the output of dmesg:

Re: RPI loose its IP address, not reason given.

Power supply. Check the voltage across TP1 and TP2. The Ethernet likes something close to 5v to work reliably. What it says on the PSU label doesn't mean much, measuring the voltage also checks out the lead to the Pi and the F3 polyfuse which can be a pain. If you've got close to 5v (> 4.8v ideally) then its likely to be a returns job.

Overheating is almost totally a non issue on the Pi. It doesn't burn enough juice. The chips are good to 85C (if it were big enough you could cook an egg on it). If you can't its likely one that was short-changed in the reflow oven.
Don't judge Linux by the Pi.......

dmesg is only the logs from the kernel. The kernel will not remove the address from an interface unless something tells it to. Check the files in /var/log, perhaps starting with /var/log/daemon.log, which is where dhclient messages go.

On the other hand, the lack of kernel logs rules out problems with power to the lan chip I think.
