Symptômes

  • Wired Network Adapter (also known as a NIC, RJ45 jack, or port, Figure 1) - Desktops and many laptops have this device that is installed inside the computer (some newer laptops use an RJ45 to USB-C dongle, Figure 2). If you do not know if you have a wired adapter that is installed, contact the manufacturer of the computer.

  • Broadband Router - The router is used to connect all your computers to a network, and to the Internet (when you only have one computer this device is not needed, as you can connect directly to the Modem your ISP provides).
 
  • Broadband Internet Service Provider (ISP) - Telephone (DSL) and Cable TV companies usually offer Internet service.

 

  1. Your Broadband Internet Service Provider (ISP) will either come to your residence or business and set up the broadband modem or send you a do-it-yourself kit.
    NOTES:
    • When using the do-it-yourself kit, follow the instructions that are provided for setting up the broadband modem or contact your ISP. Most likely, you must contact your ISP anyway to set up a username and password (when using DSL), or register your broadband modem (when using cable).
    • When you are not using a broadband router, the process is finished.

See the following instructions for setting up your wired network with a broadband router.

  1. Once the broadband modem is set up and working, remove the network or USB cable that is connecting the computer to the modem.
     
  2. Turn off the broadband modem for at least three or more minutes (this is necessary to make the broadband modem find the broadband router later).
     
  3. After the three or more minutes are up, attach the broadband router with the supplied network cable and turn the broadband modem back on.
     
  4. See the documentation that comes with your broadband router for installation instructions.
    NOTE: For more information about setting up your broadband router, see the manufacturer's website (Table 1).

  1. Plug a network cable into the RJ45 jack of the computer (Figure 1) or a USB-C to RJ45 dongle into the USB-C port of the computer (Figure 2), and the other end into the LAN port on your Modem or broadband router.
    NOTE: See the Dell Knowledge Base article Manuals and Documentation for your Dell Product, for information about how to get the manual for your computer, which provides you with the location of the RJ45 or USB-C port on your computer.

    2. In the search box type, supportassist.
    3. Touch or click SupportAssist (Desktop app).
      NOTE: When SupportAssist does not appear in the list of applications, you must download it, either on the computer that has the issue (if possible) or to a USB memory key on another device that can reach the Internet. For more information about how to obtain and install SupportAssist, browse to the SupportAssist for PCs and tablets page. You may need to provide the Service Tag or Express Service Code of your Dell computer or select your computer model from a list.
    4. Touch or click the down arrow at the bottom of the SupportAssist window.
    5. Touch or click Run under Optimize Network.
    6. After the Optimize Network is finished, touch or click the History tab.
    7. Touch or click the latest listing of Optimize Network (Manual) to review the results.
  5. Ensure that the most current network adapter drivers, computer BIOS, and router firmware are installed.
    NOTE: When the affected device has no Internet connectivity to download a driver or BIOS, you must do one of the following to get the driver on the affected device:
    • Use another device that does have Internet connectivity to download the driver and use a USB Flash drive to transfer the driver to the affected device.
    • For tablets, use the USB cable that came with the tablet to transfer the driver to the tablet, which was downloaded to another device that does have Internet connectivity.
     
  6. For more information about downloading and installing the most current network adapter drivers, see Dell Knowledge Base article Drivers and Downloads FAQs.
    NOTES:
    • The network adapter drivers are listed in the Network, Ethernet & Wireless Category subsection.
