M.2 Wi-Fi adapter for Dell and Acer notebooks

This M.2 wireless adapter fits a range of Dell Inspiron 14R, 15, 15V and 17R models as well as selected Acer and Sony laptops. It adds 802.11 b/g/n Wi-Fi and Bluetooth 3.0 connectivity through a single internal slot. The module is supplied new and ready for installation in compatible systems.

150 Mbps maximum data rate with 802.11n

The single specification that determines suitability is the peak throughput of 150 Mbps on the 802.11n standard. This ceiling limits the adapter to single-stream performance and makes it unsuitable for networks that require higher sustained bandwidth or dual-band operation.

Steady throughput at the 150 Mbps ceiling

Under continuous load the link settles at the rated 150 Mbps maximum rather than bursting higher. The QCWB335 chipset maintains this rate during extended transfers, while Bluetooth 4.0 class support handles peripheral traffic without reducing the Wi-Fi ceiling.

Questions about this item

How fast will the 150 Mbps link actually run in my laptop?

The adapter tops out at 150 Mbps on the 802.11 b/g/n band, so real-world throughput will be lower once overhead and signal conditions are factored in.

What does the M.2 interface cap for Wi-Fi and Bluetooth on this card?

The M.2 connector carries both the 802.11 b/g/n Wi-Fi signal and Bluetooth 4.0, limiting wireless speed to the 150 Mbps ceiling of the chipset.

Which slot and screw spacing does the QCWB335 need to fit?

It uses a standard M.2 keyed slot; the board matches the mounting points used in the listed Inspiron 14R, 15 and 17R models.
