Overview of Dell Precision 5520 Hackintosh WiFi Card Options

The Dell Precision 5520 Hackintosh is renowned for its capability to run macOS through Hackintosh configurations, yet users often face challenges with wireless connectivity. The integral aspect of achieving seamless WiFi functionality is selecting a card that not only fits physically into the laptop’s M.2 slot but also offers comprehensive driver support on macOS. Throughout Hackintosh communities, various models have been tested; this guide aims to consolidate the most reliable and popular options available.

Major Considerations for Replacement

When choosing a WiFi card replacement, consider the following critical factors:

1. Physical Compatibility

Most Dell Precision 5520 models utilize an M.2 (NGFF) interface. Replacement cards must be of the correct key type (typically E-key or A-key) to match the laptop's slot. Cards such as the Deal4GO and Intel models are designed in this form factor, ensuring a proper physical fit.

2. macOS Driver Support

Due to strict hardware compatibility with macOS, not all WiFi cards are supported out-of-the-box. Cards from Intel (e.g., INTEL Wireless-AC or AX series) are often favored because of their smoother integration with Hackintosh systems. Alternatively, Apple-compatible Broadcom cards like BCM94360CS2, BCM94352Z, or similar models can provide better native compatibility—even though they might require additional M.2 NGFF adapters.

3. Performance and Frequency Support

Differentiating factors include the supported wireless standards (802.11ac vs. 802.11ax) and frequency bands (dual-band support for 2.4GHz and 5GHz). Incorporating cards that can handle faster speeds and improved connectivity, like the Intel AX210 or similar WiFi 6 cards, has become increasingly important to users seeking future-proofing and faster data throughput.

4. Bluetooth and Additional Features

For users who also require Bluetooth functionality, many models come with integrated Bluetooth support. Often, Bluetooth versions range from 4.0 to 4.2, with modern cards incorporating the latest standards for better compatibility. Intel models and some Broadcom-based cards are known for their dual-functionality in both WiFi and Bluetooth.

Popular WiFi Card Replacement Options

Within the Hackintosh community, several WiFi card models have proven to be reliable. Below is an analysis of some of the most recommended options:

Intel Cards

The Intel family of WiFi cards has been widely acknowledged for their robust performance and compatibility in Hackintosh environments:

Intel AX210: This card offers WiFi 6 capabilities with dual-band support and is widely recommended for its enhanced speed and stability. It is considered one of the best choices due to its future-proof design in supporting newer standards.
Intel Wireless-AC 9260: Although slightly older, this card remains a popular choice for those upgrading their systems, providing reliable dual-band connectivity and Bluetooth integration.
Intel Wireless-AC 8265: Known for its reliable performance on macOS, this choice often strikes a balance between performance, price, and compatibility.
Intel Dual Band Wireless-AC 7260: A legacy option that continues to see usage in several Hackintosh builds, particularly when budget constraints are a factor.

Broadcom/Apple-Compatible Cards

Broadcom-based cards have long been a favorite for users looking to replicate native macOS networking hardware:

BCM94360CS2: This card is particularly notable for its Apple compatibility. When used with the appropriate M.2 adapter, it can offer a nearly plug-and-play experience on macOS. It supports both 2.4GHz and 5GHz connections and includes Bluetooth 4.0 functionality.
BCM94352Z: A variant that may require additional configuration, but offers similar benefits to the BCM94360 series. Its installation can sometimes be trickier, yet many Hackintosh users have reported success after minor tweaks.
Deal4GO BCM94350ZAE and DW1820: These models offer the benefits of 802.11ac speeds up to 867Mbps along with dual-band operations. They are popular choices especially due to widespread community support and guides on installation.

Third-Party Options Designed for Hackintosh

Aside from mainstream options, certain cards are marketed specifically for Hackintosh users:

Fenvi T919 & FV-HB1200: These cards are engineered with Hackintosh compatibility in mind, integrating seamless dual-band WiFi and Bluetooth connectivity. They offer a reliable alternative for users who want a card that has been directly optimized for macOS setups.

Installation & Configuration Process

The installation of a new WiFi card in your Dell Precision 5520 requires careful attention. It is imperative to follow the precise steps in order to avoid damage and ensure that the card functions as expected. The following is a generalized step-by-step guide:

Preparation

Ensure that you have all the required tools handy, such as precision screwdrivers and an anti-static wristband.
Download and prepare any necessary drivers or configuration files, either from official sources or Hackintosh forums.
Back up your system to prevent data loss in case of any complications during installation.

Step-by-Step Guide

Power Off & Unplug: Shut down your Dell Precision 5520 completely, remove the battery (if applicable), and unplug the system from power.
Access the Internal Compartment: Remove the bottom panel carefully using a suitable screwdriver. Several online guides, including video tutorials, demonstrate this disassembly process.
Locate the WiFi Card: Identify the existing WiFi card in the M.2 slot. In many cases, this card is secured by a metal bracket or screw.
Disconnect the Antenna Cables: Gently detach the antenna cables from the WiFi card, ensuring they do not become damaged.
Remove the Current Card: Unscrew and slide out the current WiFi card from the M.2 slot.
Install the New Card: Align the replacement card with the slot and firmly press it into place. Secure it using the bracket or screw provided.
Reconnect the Antenna: Carefully reattach the antenna cables to the new card, making sure they are properly positioned to maximize signal strength.
Reassemble the Laptop: Replace the bottom panel and fasten all screws securely.
Driver Installation: Once the system is powered on, install the necessary drivers for your new WiFi card. For Intel cards, macOS often provides native support, while Broadcom cards might require additional configuration.
