Fix: Broadcom WiFi won’t connect

Solution 1 – Upgrade your wireless adapter drivers

Usually these kind of problems are caused by driver incompatibility, but you can try to fix that by installing latest Windows 10 drivers. If you’re having a built-in WiFi card you might want to download the latest drivers for your motherboard, but if you’re using dedicated WiFi card make sure that you download drivers from the WiFi card manufacturer. Make sure that you download the latest drivers, preferably one optimized for Windows 10.

If there are no Windows 10 drivers available you can always install Windows 8 drivers in compatibility mode. To install drivers in compatibility mode do the following:

  1. Find the driver setup file, and right-click it.
  2. Choose Properties from the menu.
  3. Go to Compatibility tab.
  4. Find “Run this program in compatibility mode for” and choose Windows 8 from the list.
  5. Click OK and Apply to save the changes and then run the setup.

Update drivers automatically

If you don’t want the hassle of searching for drivers on your own, you can use a tool that will do this for you automatically. Of course, as you’re not able to connect to the internet at the moment, this tool won’t be useful. However, once you get online, it will help you to keep all your drivers up to date, so you won’t be in this situation anymore.

Tweakbit’s Driver Updater (approved by Microsoft and Norton Antivirus) will help you update drivers automatically and prevent PC damage caused by installing the wrong driver versions. After several tests, our team concluded that this is the best-automatized solution.

Here is a quick guide on how to use it:

  1. Download and install TweakBit Driver Updaterdriver updater starting window
  2. Once installed, the program will start scanning your PC for outdated drivers automatically. Driver Updater will check your installed driver versions against its cloud database of the latest versions and recommend proper updates. All you need to do is wait for the scan to complete.

To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.

    Note: Some drivers need to be installed in multiple steps so you will have to hit the ‘Update’ button several times until all of its components are installed.

  1. Open Command Prompt as administrator. You can open it by pressing Windows Key + X and choosing Command Prompt (Admin) from the list.
  2. Enter netcfg –s n in Command Prompt.
  3. You should get a list of networking protocols, drivers and services. Search the list for DNI_DNE. If the DNI_DNE is
  4. present proceed to the next step. If there’s no DNI_DNE on your list, skip this solution.
  5. Enter the following line into the  Command Prompt and press Enter:
    • reg delete HKCRCLSID{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f Wi-Fi-does-not-work broadcom

We hope that at least one of these solutions helped you with your problem with Broadcom WiFi. However, if you didn’t solve the problem, even after applying these fixes, you can check out our article about problems with WiFi adapter in Windows 10, and maybe you’ll find the solution there.

Solution 3 – Delete your wireless profile

If updating the Broadcom driver didn’t get the job done, we’re going to try with reseting your network profile. The first thing you need to do is to delete it:

  1. Go to Search, type cmd, and open Command Prompt as Administrator. 
  2. When Command Prompt stats type in the following command and press Enter: netsh wlan delete profile name=”WirelessProfileName” (be sure to replace WirelessProfileName with the actual name of your wireless connection)

Once you reconnect, the new wireless profile will be created automatically.

Solution 4 – Run the Troubleshooter

Now, let’s try Windows 10‘s built-in troubleshooting tool. This tool can resolve various system issues, including our network problem. Heres how to run it:

  1. Go to Settings.
  2. Head over to Updates & Security Troubleshoot. 
  3. Select Internet Connections, and go to Run the Troubleshooter. 
  4. Follow further on-screen instructions and let the process finish.
  5. Restart your computer.

Solution 5 – Reset your router

The problem can be caused by improper router configuration, and of course, you can fix it by resetting your router. To do that, just press the reset button on your Realtek router, or open the router settings and select the reset option. Before resetting your router you might want to save and export your configuration so you don’t have to enter it manually. For more information on how to reset your router or how to export your router’s configuration, be sure to check your router’s manual.

Solution 6 – Check if the network is enabled

Although it sounds unlikely, it’s possible that your Broadcom device isn’t even enabled. So, make sure to eliminate that possibility:

  1. Go to Search, type devicemngr, and open Device Manager.
  2. When Device Manager opens, locate your wireless adapter and double click it to open its properties.
  3. Go to Driver tab and look for Enable button. If you don’t see the Enable button, it means that your device is enabled and working.

Solution 7 – Reset the network

If none of the previous solutions worked, the last thing we’re going to try is resetting the network. Here’s how to do that:

  1. Go to the Settings.
  2. Navigate to Network & Internet > Status.
  3. Scroll down and locate the Network reset option. This feature allows you to set your network component to default. You might need to reinstall certain network software afterward.
  4. Go to Reset now, and click Yes.
  5. Wait until your PC restarts and then check if your Ethernet connection is available.
