Yes, okay. It's common to not update a BIOS if you're not having any problems. Updating a BIOS can be risky business (if it ain't broke, don't fix it). But in your case, it will be necessary.
Meanwhile, I'd like you to try something on the Realtek NIC:
In Device Manager, highlight the Realtek PCIe GBE Family Controller.
Right-click and select Update Driver
Select Browse my computer for driver software
Select Let me pick from a list of available drivers on my computer
Make sure the box is checked to Show compatible hardware
What does it show, other than Microsoft Driver version 9.1.406.2015 dated 4/6/2015?
