Today I updated my kernel from this state: to a newer version.
After the update my BPIR2 had no connection to the internet. I noticed that my PI indicates that there is no cable connected to the wan port (output from eth-tools). But it is… After a downgrade everything worked fine again. Any ideas?
BTW, this is my interface config … but I do not think the problem is there:
