Windows 7 Unable to transfer at Gigabit speeds

[Carelen]

I can’t get anything faster than 5Mbs transfers over my network. This is what I have connected. I’m using a Dlink DIR-655 Router, set to connect at 1Gbps, Western Digital NAS drive, it says it’s connected at 1Gbps, and my laptop is set to connect at 1Gbps also. My laptop has a Realtek NIC, with the lastest drivers that I can find. Every thing is set to 1Gbps and, they all connect at that speed, but transferring between my NAS and my laptop, I ONLY get right at 5Mbs. Everything is connected with Cat5e cables, no long runs or anything. I’ve looked at several forums to figure out what I can do to get higher transfer speeds, but nothing seems to help. Anybody got any ideas, because I’m running out of them.

It seems like you're facing slow transfer speeds on your network despite all devices being set to connect at 1Gbps. Slow transfer speeds are frustrating, but let's troubleshoot this issue step by step to see if we can improve the situation. Here are some suggestions to help you potentially increase your network transfer speeds:

Troubleshooting Steps:​

1. Check Network Bandwidth:
   • Make sure that the network interface cards (NICs) on both your laptop and NAS are operating at the correct speed (1Gbps).
   []Update Firmware/Software:
   • Ensure that the firmware on your Dlink DIR-655 Router and the software on your NAS and laptop are up to date.
   []Check for Network Bottlenecks:
   • Verify if there are any other devices on the network consuming bandwidth that could be affecting transfer speeds.
   []Check for Interference:
   • Ensure there is no interference from other wireless devices or neighboring networks causing disruptions.
   []Try Different File Transfer Methods:
   • Experiment with different file transfer methods to see if speeds vary (e.g., using FTP instead of SMB).
   []Jumbo Frames:
   • Enable Jumbo Frames on your devices if supported, as this can potentially improve transfer speeds.
   []Quality of Cables:
   • Although you mentioned using Cat5e cables, ensure that the cables are in good condition and not damaged.
   []Network Configuration:
   • Check the network settings on your devices to ensure they are optimized for performance and not set to a lower speed manually.
   []Network Traffic Monitoring:
   • Use network monitoring tools to identify any bottlenecks or issues that could be impacting transfer speeds.
2. Test with Different Devices:
   • Try transferring files between different devices to isolate if the issue is specific to the laptop or NAS.

     Additional Considerations:​

   • Realtek NICs and Drivers:
   • Realtek NICs have been known to have performance issues in some cases. Ensure you have the latest drivers specifically designed for your laptop's model.
   • Network Configuration:
   • Double-check settings like duplex mode, auto-negotiation, and any power-saving features that might be impacting performance.
   • Professional Help:
   • If none of the troubleshooting steps yield positive results, consider consulting a networking professional who can diagnose and resolve the issue. By following these steps and guidelines, you should be able to pinpoint the factors affecting your network transfer speeds and work towards improving them.
