Even if you firmly believe that your Ethernet cable is perfectly fine, and even if this cable worked fine before, swapping it out for another, proven cable, or a brand new Cat 6 cable, will almost certainly solve the issue with a minimum of troubleshooting and headache. If this is set correctly and you are still having the issue then it could be a couple things, although it is important to note up front that this is almost always an issue with an Ethernet cable. Auto-Negotiate is the correct setting for Gigabit speeds with our adapters. This option is under the Advanced tab of the adapters properties, just right click the adapter and choose properties. From the Device Manager, you can check to see that the Killer adapter is set on Auto-Negotiate. The only setting that is of concern for a gigabit connection is that the adapter is set to Auto-Negotiate. We're sorry to hear that you're having troubles with your new Gigabit connection!
