    Is this a DHCP problem?

    hope someone can help on this.

    I have lost internet access after installing latest batch of updates on 12.04.
    My laptop sees my wireless router OK.

    ping returns 'Unknown Host' for external sites.
    ping local devices returns '100% packet loss'.
    PING 127.0.0.1 gives '0% packet loss'

    Is this a DHCP problem and how can I check?

    if it is a dual boot you can save the file directly to your windows desktop, that said
    i assume you are using wireless, try hardwire
    have you tried to connect to your wifi?
    edit connections with nm-connection-editor

    Code:
    lspci | grep Ethernet

    Tried wired direct to router. This allows ping to reach local devices with no packet loss. External sites return
    Code:
     6 packets transmitted 1 received 83% loss
    With the browser I get limited and slow link to external sites.

    The lcsi returns
    Code:
