Yesterday I installed a fresh version of W7 on a new partition and my speeds were back up to 300/15. This would mean it is not a hardware issue and was indeed either a Windows setting or a application. I then just decided to reinstall W7 because it was getting a bit slow anyways. For now I will call it case closed.

I agree. I am starting to lean towards an obscure (to me) Windows 7 setting or a faulty Mob. I will verify my QoS settings in both the router and Win7 again, but I did disable it via the adapter settings and changed QoS Packet Scheduler – Limit reservable bandwith to 0% and tried disabling it.

When you say doesn't need to draw 300Mbps what do you mean? I was able to achieve these speeds with two other machines running the same speed tests. Thanks.

Never mind I found it. Quote button.

I am sorry I am new to forums. How do you show the post in your reply?

Re: Gilgul It could be a faulty MoB, but that is difficult to troubleshoot without a replacement.

Re: GabeThePCHelper. When I was troubleshooting yesterday I turned off the other computers, so I don't think it is a split connection issue.

Hello All, I hope someone can help me out with this. I currently pay for 300Mbps/15Mbps internet. I am able to achieve these speeds via wired network connection from my Asus RT-N56U router on two computers; one desktop and one laptop. My other desktop computer is only able to achieve a maximum of 140Mbps/15Mbps using a Cat 5e network cable. I have tried several different things to troubleshoot this slow speed (listed below). The only thing I have not yet done is re-install Windows 7. If anyone has any other ideas please let me know. Troubleshooting Completed: Ran Windows 7 in safe mode with networking. Replaced the network cable with a new one (Cat 5e). Tested the new cable on a laptop and was able to get 300/15. Changed router port. Purchased and tested a new PCI Express TP-Link TG-3468 10/100/1000Mbps Gigabit PCI Express Network Adapter. Same speeds as on board NIC. Verified the NIC speed was set to 1.0 Gbps Full Duplex. Local Area Connection Status shows speed of 1.0 Gbps. Changed QoS Packet Scheduler – Limit reservable bandwith to 0% and tried disabling it. Disabled the following via command line; netsh int tcp set heuristics=disabled netsh int tcp set global autotuninglevel=disabled netsh int ip set global taskoffload=disabled Reset TCP/IP to defaults by; netsh int ip reset Tried various combinations of NIC properties.
