System is Raspi 5 with latest Dietpi Image for this type of raspi.
Installing worked ok, updating software etc etc also ok. I changed from DHCP to static IP via Dietpi-settings. Also that work at first. Within the next 30 mins all in a sudden the connection to the raspi stop’s ( connection via SSH ) . Checking direct at the raspi and found that I could login normaly. Checking via Dietpi-settings and testing Internet connection it say “no connection possible”
Back and fwd with Static and DHCP and it ended up with the same problem.
Any hint would be appreciated , tks

did you checked if an IP address has been assigned?

ip a

Or kernel log for critical messages

dmesg -l 0,1,2,3

Hi,

pls see attached some screen shots :

After changing to static ( ip 1.42 )

This morning I made a fresh install and it took again 30-40 mins until the ip settings changed again

At present system boots from an NVME drive, later I will try from USB → ssd and see what happens there

it seems to have a valid IP address 192.168.1.42. Are you able to ping gateway? or could the IP address be assigned by your DHCP server to another device resulting duplicate IP? Did you tried to use a STATIC IP address from outside DHCP address range?

Hi,
the DHCP Server starts @ 192.168.1.50 , everything below is used for static IP’s
I also checked all the used IP’s , but no duplicates found. Most of the wifi stuff is using DHCP and the wired PC/TV’s etc have fixed IP’s
Starting all over again now

Cable not connecting well?? Power issues? Check to see if the ethernet transceiver chip isn’t getting too hot

Hi,
temperatures are ok, the chip mentioned is quite cool. The Dietpi Dashboard is complaining that it’s too cold. But I also took a measurement of the mentioned chip.
I have narrowed it down to a problem with the cable modem ( Fritzbox 6591 ) , power off and after a few moments power on. After that the system is running stable. Fingers crossed.
Loading / installing all of my software will take a while.

That was a bit premature. Just now I lost the connection to the Raspi again. No SSH connection possible. Went upstairs and noted that no internet connection was possible ( Dietpi.config ) But IP-settings still as before. Before doing anything stupid I rebooted the machine again and all back to normal again , but still :confused:
