If you have an Intel WiFi Link 5100 Series wireless adapter in your Mac, you may be wondering how to install the driver for it. The Intel WiFi Link 5100 Series is a dual-band 802.11a/b/g/n wireless adapter that supports up to 300 Mbps of data rate and up to 2x2 MIMO antenna configuration. It also supports IntelÂ PROSet/Wireless Software, which provides enhanced features and management tools for wireless networks.
However, the Intel WiFi Link 5100 Series is not natively supported by macOS, so you need to use a third-party kernel extension (kext) to enable it. One of the most popular kexts for Intel wireless adapters is itlwm, which is based on the OpenBSD Project and supports a wide range of Intel wireless devices.
In this article, we will show you how to download and install itlwm kext for your Intel 512an Hmw wireless adapter on macOS. We will also show you how to load and unload the kext, how to check the status of your wireless connection, and how to troubleshoot some common issues.
Step 1: Download itlwm kext
The first step is to download the latest version of itlwm kext from the GitHub repository[^2^]. You can choose between two versions: itlwm and AirportItlwm. The difference is that itlwm uses a separate app called HeliPort to manage the wireless connection, while AirportItlwm integrates with the native macOS Wi-Fi menu bar icon. Both versions have their pros and cons, so you can choose the one that suits your preference.
For this tutorial, we will use AirportItlwm as an example. To download it, go to the Releases page[^2^] and find the latest release that matches your macOS version. For example, if you are using macOS Big Sur 11.6, you should download AirportItlwm-Big_Sur-v2.1.3.zip. Extract the zip file and you will find a kext file named AirportItlwm.kext inside.
Step 2: Install itlwm kext
The next step is to install the kext file to your system. There are two ways to do this: using a kext installer app or using Terminal commands. We recommend using a kext installer app as it is easier and safer. One of the most popular kext installer apps is Kext Utility, which you can download from here. After downloading and launching Kext Utility, drag and drop the AirportItlwm.kext file onto its window and enter your password when prompted. The app will automatically install the kext to your system and rebuild the cache.
If you prefer using Terminal commands, you can follow these steps:
Open Terminal app from Applications/Utilities folder or Spotlight search.
Type sudo mount -uw / and press Enter. Enter your password when prompted. This will mount your system partition as writable.
Type sudo cp -R /path/to/AirportItlwm.kext /Library/Extensions/ and press Enter. Replace /path/to/AirportItlwm.kext with the actual path of the kext file that you downloaded.
Type sudo chown -R root:wheel /Library/Extensions/AirportItlwm.kext and press Enter. This will change the owner and group of the kext file to root and wheel.
Type sudo chmod -R 755 /Library/Extensions/AirportItlwm.kext and press Enter. This will change the permissions of the kext file to 755.
Type sudo kextcache -i / and press Enter. This will rebuild the cache for your system partition.
Type sudo reboot and press Enter. This will reboot your system.
Step 3: Load itlwm kext
After installing the kext, you need to load it into your system. ec8f644aee
