Note: If I put the PC to sleep (tested up to 5 mins) and wake it back up, pings pick back up. I've tried the various "Adapter Types" in VirtualBox to no avail. Restarting the guest Linux networking, a VM reboot, or a disable/enable of all Windows' interfaces does not regain network connectivity to the Linux VM. If it takes more than 5 seconds for me to plug the cable back in, the ping does not pick back up and I need to shut down the VM and cold boot it in order to restore networking between the VM and LAN. If I start a ping from within the Linux VM and disconnect the Ethernet cable from the bridged interface (Intel Ethernet Connection I219-LM) and plug it back in within 5 seconds, the ping picks back up where it left off. The VM can communicate with my LAN and vice versa. Networking functions 100% between the VM and LAN if I power on the VM with the Ethernet cable plugged in to the bridged interface (Intel Ethernet Connection I219-LM). 2 = Bridged Adapter (Intel Ethernet Connection I219-LM).
