Not for ThinkPad or desktop builds

The supplier notes that IBM Lenovo ThinkPad laptops will not accept this adapter. It is also unsuitable for NGFF M.2 slots and for desktop PCIe x1 slots. Buyers who need those interfaces should look at other parts.

Half-mini PCIe interface constraint

Only half-mini PCIe motherboard sockets can accept this card. The physical keying prevents installation in full-size mini PCIe, NGFF or desktop PCIe x1 slots. Verify the slot type before ordering.

Questions about this item

Will the half Mini PCIe slot on my Presario CQ45 accept this AR5B125 card without an adapter?

Yes, the card measures 30 mm by 26.8 mm and is designed for half Mini PCIe slots, matching the Presario CQ45 and Compaq 1000 or 2000 series.

Does the AR9485 chipset limit throughput to 150 Mbit/s even on an 802.11n network?

The adapter is rated at 150 Mbit/s under the 802.11b/g/n standard, so that is the maximum link speed it can negotiate.

How warm does the card get when running continuously on Windows 10?

The supplier notes that on Windows 8, 8.1 or 10 you may need to insulate the twentieth contact with adhesive plaster to maintain a stable signal, which suggests the card can operate continuously once that step is taken.
