Questions about this item

Does the Intel Centrino 1030 card ship with antenna cables or a driver disc?

The listing states no accessories such as cables or manuals are included unless otherwise noted; the card comes exactly as shown in the photos.

My laptop is a Dell Inspiron 15R N5110 — will the 11230BNHMW fit and work?

The N5110 appears in the compatible models list alongside the part numbers 7KGX9 and CN-07KGX9, confirming a direct fit for that chassis.

What real-world throughput should I expect from the 270 Mbps link rate on this 802.11 b/g/n adapter?

The 270 Mbps figure is the maximum physical-layer rate; typical sustained throughput in a working laptop is lower due to overhead, interference and the capabilities of the connected router.
