Ubuntu Ethernet Problems

[Jdogbf]

I am in a hardware class at school and we got to install it and play with it. I found out that it is really cool so I tried at home. Got it installed but it is not connecting to the internet at all. It is by Ethernet and on windows it works, on Ubuntu it does not... Any tricks?

Yeah, minus a few hard drives. Router is a netgear router AC1600, Hardware #  R625

The hard drives missing is my new C drive and the drive Ubuntu is on. C drive is a PNY CS1200 480gb and Ubuntu is on the same series but a 120gb. On comcast so the router in then into the comcast one.

Well from a quick Google search, that card has been giving people hell for years. Like, so bad that people end up buying new network cards. The first thing to try is to check for an "Enable IOMMU" option in your BIOS. The fix seems to be either just the IOMMU option, just installing the Linux driver from Realtek, or a combination of the two.

Ok I will try this out

You can try to install the official Realtek driver, but the link I found didn't work so you'd have to look for one yourself.
I think you will probably need to get a new NIC if the basic solutions won't work. Don't worry, those cards are dirt cheap.

So I went to try and install the drivers and enable that option in the BIOS, and it destroyed all data on all of my drives. Don't know how, but it did. Had to reinstall windows and the whole 9 yards. Maybe will pick up Ubuntu again in the future, but for now I will stick with windows.
