Here is some update. Eth0 (my network card) is still having problems. When is is configured with a static ip, the card shows up in the KDE system information and I can ping my router and my ISP dns server.
When I configure eth0 with a dynamic ip using the control panel, eth0 could not obtain a DHCP lease, this did not happen with dapper. -- Install edgy eft breaks compatibility Realtek 8169/8110 NIC https://launchpad.net/bugs/63209 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
