⚙️ Fit Notes

• This is a Half Mini PCIe card and is not compatible with M.2 / NGFF wireless slots.
• HP and Lenovo systems may enforce BIOS WLAN whitelists. Even if the slot matches physically, some systems only accept specific approved wireless module IDs/spares.
• For HP systems listed above, the documented approved AR9462 combo spare is 676786-001.
• Some generic marketplace listings note AR5B22 cards may not work in certain HP/Lenovo systems unless the exact OEM-approved version is used. Always match your original card label and approved spare when possible.
• ASUS and additional Acer models may support this card if they use a Half Mini PCIe WLAN slot and do not enforce a restrictive whitelist. Match by original card form factor and connector layout before ordering.
• Driver availability varies by system/OS. For some systems (such as XPS 13 L322X), OEM driver packages are available under the Qualcomm Atheros Killer Wireless-N 1202 designation.
