Hi phenigma,
I think I might have identified the problem. My core has only one NIC,so I'm using a USB adapter for second card, that I think is badly configured. I'm no expert but, I had the onboard nic conected to adsl router and the usb nic as internal nic, and three devices conected to the switch (the rpi i was Trying to boot into LMCE, a VU Zero receiver, and a hummingboard running openelec).Both the humming board and the VU zero got internet through the Core. So I assumed everything was ok with the usb card. I even reinstalled the core...
Like this, the core assumes IP 192.168.1.172 from my adsl router.
if I change the cable, connect the adsl router to the usb nic, I still get internet, but going to webadmin network config, it shows an ip that is not in my adsl router range (169.128.8.69), and the core identifies other devices that run in the adsl router network (PC, cable box, etc.)
so I'M thinking the USb nic doesn't show the correct IP adress and when the pi boots second time is doesn't find the core.
I'd Like to knoe 2 thingd if you can help. First is if to boot pi as MD do I have to have Internet on the core, or can I just update the core and then use the on board nic as eth1, and boot the MD.?
and if I chage the onboard nic to eth1 and the usb to eth0, if it is badly configured but still has internet is that a problem?
don´t mind of other devices because this core is only for testing purposes, so I can test before I use it in me home setup.
I'd like to know if you think this might really be the problem, and about the changes to do, or if there is another way.
Thanks
NM
