How To Fix An Acer Predator Helios 300 Ethernet Not Working – WiFi

If you can’t get your Ethernet connection to work on your Acer Predator Helios 300, try the following fixes before taking the laptop to an Acer Service Center:

Enable Ethernet in Device Manager

If you haven’t enabled Ethernet on your laptop, it definitely won’t work. So before you try other fixes, check whether Ethernet is enabled.

  1. Right-click the Start Menu and select Device Manager.
  2. Double click the Network Adapter category to expand it.
  3. Locate the Ethernet connection device and right-click on it.
  4. Choose the Enable option if it’s available.

If you see a Disable option, it means your Ethernet device is enabled. So proceed to the next solution.

Enable Ethernet in Network & Internet Settings

Confirm that Ethernet is enabled in Network & Internet settings by following these steps:

  1. Right-click on the Ethernet or WiFi icon on the right side of your taskbar.
  2. Select Open Network & Internet Settings.
  3. On the new window, scroll the Right pane menu and click the Change adapter options.
  4. A new window should pop-up showing all your internet connections.
  5. Right-click on the Ethernet option and click Enable.

Update Your Ethernet Drivers

Your Ethernet connection might fail to work if you have outdated drivers. You first need to check the version of your Ethernet device and confirm if new versions are available.

Here is the method we recommend for updating your drivers:

  1. Go to the official Acer’s Drivers and Manuals page and key in your device’s info.
  2. You’ll be directed to a new page that contains the latest drivers.
  3. Expand the driver’s category and locate the latest LAN drivers.
  4. Download the driver and extract them to your desktop or a folder of your choice.
  5. Open Device Manager.
  6. Expand Network Adapters.
  7. Right-click on the Ethernet device and choose Update driver.
  8. Choose Browse My Computer For Drivers.
  9. Hit Browse and choose desktop or the folder which you extracted the files to.
  10. Click Next and follow the instruction to complete.

Restart your laptop and confirm if the Ethernet port is now working.

Uninstall Current Driver

Corrupt or missing drivers can also prevent your Ethernet from working. In this case, you’ll have to uninstall your current Ethernet driver. Follow these steps:

  1. Open Device Manager and expand Network Adapters.
  2. Right-click on Ethernet device and choose Uninstall device.
  3. Confirm you want to uninstall to complete the process.
  4. Shut down your laptop and boot it again.

Check Network Cable

If you have the Ethernet connection enabled, you are advised to check its status. The status should inform you whether the computer recognizes the cable or not. Here is how to go about it

  1. Open Settings by pressing the Windows key + I.
  2. Open the Network and Internet option and click on the Ethernet option on the left pane menu.
  3. Your Ethernet connection should either show “Connected” or “Not Connected.” If it says Not .Connected, it means the computer can’t recognize the Ethernet cable.

You might try disconnecting the Ethernet cable and connecting it again to check if it will work. Alternatively, you can try connecting the cable to a different port on the modem, switch, or router.

If that doesn’t work, try using a different Ethernet cable.

Turn Off Your Antivirus or Firewall

Most antivirus software can interfere with your internet connection without you knowing. So, to rule out such cases, you should temporarily disable your computer’s firewall and antivirus.

Restart your laptop and check whether the wired internet is working. If it’s working, you might have to try an alternative antivirus software or contact your antivirus vendor for solutions.

Flush DNS & Reset TCP/IP

  1. Run command prompt as an administrator or open Windows powershell (admin)
  2. Type the following command and hit Enter after each one:

ipconfig / release

ipconfig /flushdns

ipconfig /renew

  • Open Admin command prompt once more and type each of these commands while hitting Enter:

ipconfig /flushdns

nbtstat –r

netsh int ip reset

netsh winsock reset netsh winsock reset catalog netsh int ipv4 reset  reset.log

Run The Troubleshooter

Windows troubleshooter can help identify problems with your Ethernet and correct them. Here is how to do it:

  1. Righ-click the Internet Icon on the right side of your taskbar.
  2. Select Troubleshoot problems.
  3. The troubleshooter will start detecting problems and prompt you to choose which network adapter to diagnose.
  4. Tick on the Ethernet option and click Next.
  5. Follow the instructions given to fix the issue.
