I have the Killer E2600 controller and installed a Realtek 2.5 gbs ethernet card for more speed ( 1.5 gbs internet package) but I am unable to use the Realtek. If I disable the Killer, I can’t get online at all. How do I stop using the Killer and start using the Realtek?
What you’ll likely need to do is go into BIOS Setup and disable the E2600 device. Once disabled, the device will not appear in Windows and should not conflict with the Realtek device. I would also uninstall the Killer software/driver stack.
Hope this helps,
