Are you plugging a NIC into the riser or are you saying you plug the riser in and your onboard NIC stops working.

I wonder if the slot shares lanes with the Ethernet adapter. What motherboard are you using?

I take it this is a PCI_ex1 to x16 riser cable? If its the kind from the early days of crypto-mining those have been known to not be the most reliable.

 

Did you try putting the riser in a different slot?

Did you try all the x1 slots? Do you lose internet on all of them or just 1?

it works with the x16 slots but not the x1 slots

What revision is the motherboard? It's painted on the motherboards silkscreen by the very most bottom left screw. It should say REV:#.#

i'm not at home at the moment so i cant check but i'm pretty sure its a REV 1.0

i have the f7 bios

[Windows7ge]

The manual doesn't mention sharing lanes between slots. I wonder if all the x1 slots go through the PCH and both x16 slots go to the CPU. Perhaps the PCH is to blame here. You may have to locate a setting in the BIOS that changes how the system distributes lanes.

 

Though to contradict that you put a sound card in and it was fine. I'm out of ideas. The only thing I can think of is something is wrong with the riser itself.

 

Why do you need it?

Well worst comes to worst you said the x16 slot works. Check the BIOS and see if it says anything about distributing lanes. Sometimes when certain ports are being used at the same time things stop working.
