I am running this on a Supermicro without any problem. You say you lost your "static IP ", How are you assigning the IP? Threw the router or hard-coding the NIC? How many NIC's are on Your box? One thought is the default gateway in DSM mite of changed, Go to control panel-> network-> network interface and click the down arrow net to each NIC till you find the one with the IP that you use, Click edit and make sure the "set as default gateway" is checked.
