    Shared internet disconnects in clean 11.10, but no when upgraded 10.10->11.04->11.10

    I'm having a very strange problem:

    I installed a clean 11.10 desktop, two NICs: one configured as DHCP from my router, the other is for sharing internet.

    But the shared connection keeps connecting/disconnecting every few seconds (I can tell because of the constant messages in the desktop).

    If I install a clean 10.10 version, the shared connection works flawlessly. I then upgraded to 11.04 and then to 11.10 and every time the connection works fine.

    So, the problem seems to be NOT hardware related, it's only present when I install a clean 11.10 (or 11.04)

    I checked everything I can think of:

    * Yes, I re-downloaded my 11.10 ISO and burned a second CD to install it again. Same problem.

    * No, there's nothing else installed: I just installed Ubuntu and change the Network settings to share the connection.

    * Yes, I switched the cabled and change the shared NIC <--> Internet NIC. The problem's still there, both cards are differents, so it's not specific of one of them.

    * If I change back the shared connection to auto-DHCP, the continous connect/disconnect message dissapears and I can ping this card without problems.

    * I installed all updates for both a clean 11.04 and 11.10 with no luck.

    * I even changed to a completely different PC with another 2 network cards. Still the same.

    * I used 32 bits desktop version *most* of the time, but also tried a 11.10 64 bits version with the same results.

    Any ideas will be very appreciated.

    Thanks.
