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.
    • Increased/decreased receive buffers
    • Disabled energy efficient Ethernet
    • Increased/decreased Receive side scaling queues
    • Etc..
  • Updated all NIC/Chipset drivers from Asrock website.
  • Installed ASRock XFast LAN utility
  • Disabled ASRock XFast LAN utility
  • Uninstalled ASRock XFast LAN utility

My PC Specs:
  • Windows 7 Ulimate Ed SP1
  • Intel - Core i5-4690K 3.5 GHz Quad-Core Processor
  • ASRock - Z87 Extreme4 ATX LGA1150 Motherboard
  • Onboard Intel I217 V NIC
  • Kingston - HyperX Fury Black 16 GB (2 x 8 GB) DDR3-1866 Memory
  • MSI - Radeon RX 580 8 GB ARMOR OC Video Card
  • Shaw Router acting as bridge
  • Asus RT-N56U router
 
Maybe it is something related to the browser running the test.

First unstall any lan accelerator software. You can not affect traffic outside your machine and the problem is never competition for bandwidth inside your machine unless you are doing something silly.

I would try running a old program called IPERF between your laptop and desktop. This is a extremely simple program that is not affected by cpu/memory or much else. It is purely a simple network test. You should actually get over 900mbps in both directions if things are working well.

The goal here is to see if it is really a network or nic issue or if it might be something else.

I have tried both chrome, IE and various speed tests all showing tha same results. I will try and run the IPERF network test between my two machines.

Thanks.

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.
