If you’re thinking about upgrading your laptop’s Wi-Fi card, it’s important to know that many models have a whitelist that only allows specific Wi-Fi cards listed in the service manual to work. If your laptop only has two Wi-Fi antenna wires, your best choice for a new card is a dual-band N card that can handle up to 300 Mbps.
However, if your laptop has three antenna wires, you can go for a higher-speed card that supports up to 450 Mbps. One option to consider is the Intel Centrino Ultimate-N 6300, which is known for its faster transfer speeds. This card is compatible with your machine if it has three antennas and has the part number HP 572511-001. You can check out more about this card on Intel’s website here.
While some people have used Atheros cards too, it’s hard to find detailed specifications or purchase options for them, so sticking with the recommended options is usually easier.
To find compatible cards, refer to the service manual linked here c02847569.pdf. This manual contains a list of supported Wi-Fi cards and the correct HP part numbers. Remember, any Wi-Fi card you buy must have the exact HP part number printed on it; otherwise, it won’t work with your device.
By choosing a compatible Wi-Fi card based on this information, you’ll ensure a smooth upgrade and proper operation of your laptop’s wireless network.
