Network keeps resetting

I found references to this bug starting with VMware Player v8, so I'm not exactly sure if this is the same problem. I've been noticing a resetting of my network every 10-15 minutes. Here is a sample of what happens (this is 10 minutes after a reboot):

In the articles I've read about this, they all point to DHCP on the host being the culprit. Since I'm using a static IPv4 address (with IPv6 disabled), this should not be a consideration. Is there anything else I can look at? The network drop is killing my host for about 20-30 seconds - very annoying!
