Investigating Slow Network Performance on Dell Inspiron Laptops

You just signed up for a gigabit broadband plan and got your new docking station or USB Ethernet adapter supporting gigabit connectivity. So you hook it up to your Dell Inspiron system, jack in the Ethernet cable, and navigate on over to speedtest.net or fast.com to see those sweet speeds… Only, there’s a problem — you’re getting embarrassingly low download or upload speeds when you’re paying your ISP for much more.

Before grabbing the pitchforks and suspecting the USB Ethernet device to be the issue, chances are, there is a Dell-provided software on your computer that’s causing the trouble.

After working with a customer experiencing slow Ethernet speeds through their Plugable UD-3900 docking station, we discovered the sneaky culprit at hand was SmartByte, a program that claims to prioritize your network traffic in ways to improve the quality of the videos that you watch.

However, a Google search of “SmartByte” immediately reveals a wave (Dell forum post, Tenforums post, Reddit post) of frustrated users who report SmartByte slowing down their network speeds on their system. Of course, it’s difficult to validate every single network issue (or anything worse) that is being reported about SmartByte, but it is clear that this program is prone to causing performance headaches for many folks using a wide range of network devices.

After all, this was enough for Dell themselves to essentially acknowledge the problems of SmartByte by releasing a support article walking through steps to resolve these networking issues, with the last steps ultimately being to disable SmartByte!

All this being said, how can you tell if SmartByte is installed on your Dell Inspiron computer?


Check for SmartByte

  1. Press the “Windows Logo” Key + Q to open a search prompt
  2. In the Search prompt, enter Control panel
  3. Click on Control Panel (Desktop app)Control Panel listing in search view
  4. Under Programs, click on Uninstall a program
    Control Panel option
  5. See if SmartByte Drivers and Services is listed as an entry
    SmartByte listing in Control Panel Programs

 
If you do see SmartByte listed, don’t panic! From there, you can double-click the entry to run through its uninstaller and completely remove it from your system. Keep in mind that SmartByte may be reinstalled to your system through Dell SupportAssist, so you may need to uninstall this as well to prevent SmartByte from coming back.


Disable SmartByte

Another option is to disable SmartByte on your computer. The software will still exist on your system, but it should stop manipulating your Internet traffic. Disabling SmartByte and running a speed test is a good quick way to see if SmartByte is indeed slowing your system.

  1. Press the “Windows Logo” Key + Q to open a search prompt
  2. In the Search prompt, enter SmartByte
  3. Click on SmartByte (Trusted Microsoft Store app)SmartByte listing in search view
  4. In the SmartByte application, click the slider to the right to turn off SmartByteSmartByte user interface

Networking issues such as these can often be quite complex and difficult to isolate as there are many factors that vary from environment to environment.

    Hi, I have an Inspiron laptop that I bought about 5 or 6 years ago. I complained to my Internet provider RCN why my speed is only 93 when my subscription says its 155. Their tech guy came and tested from his laptop my modem/router, and the speed is 155 and above.

    He told me that my Ethernet port is the problem. Will you product/s be able to remedy this port problem. If yes, please let me know which type/model I can buy. Thanks, Ray

      Hello Ray,

      Thanks for reaching out to us! I do apologize for any trouble you’ve had with slower speed. I would first suggest to check if your computer has the SmartByte program installed as listed in this article above. If it is installed, please follow the steps to uninstall it and see if that makes a difference.

      For your computer and network need, I would suggest our USB2-E1000 adapter. You can view compatibility information, frequently asked questions and other helpful details about the adapter at this link: https://plugable.com/products/usb2-e1000/.

      This adapter is USB 2.0, and has a theoretical max speed of 480 megabits per second (mbps). Most folks report speeds in the range of 250-350 mbps. I do want to mention that there are a number of factors that determine network speed, and that we cannot guarantee the exact speed that you will receive. I hope this helps!

      Please feel free to reach out to us directly at: support@plugable.com with any further questions, and we’ll be here to help.

      Thank you,

      Kevin
      Plugable Support
