I can't find /etc/modprobe.conf nor /etc/modprobe.d/0.

It doesn't connect with an older kernel either.

I don't see anything obviously wrong:

Settings for eth0:
    Supported ports: [ MII ]
    Supported link modes:   10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
    Supports auto-negotiation: Yes
    Advertised link modes:  10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
    Advertised pause frame use: No
    Advertised auto-negotiation: Yes
    Link partner advertised link modes:  Not reported
    Link partner advertised pause frame use: No
    Link partner advertised auto-negotiation: No
    Speed: 100Mb/s
    Duplex: Full
    Port: MII
    PHYAD: 13
    Transceiver: external
    Auto-negotiation: on
    Supports Wake-on: g
    Wake-on: d
    Link detected: yes

Is it time to reinstall?

John.
