[Bug 31914] Re: Network Communication between "eth0" and "dhcp", only last for 1 minute. On NIC Vendor: Davicom Semiconductor, Inc. Device: 21x4x DEC-Tulip compatible 10/100 Ethernet. NIC Bus Type: PCI

I have the same issue with a broadcom NIC. Mine stays up for the most
thirty seconds whether I am on the router or not. I also tried setting a
static IP and I still have the same issue. If I run mii-diag -r the
connection will come back up half of the time.
