DELL DW1503 Wireless-N Half-Height Mini-PCIe Card V91N8

Dell DW1503 Wireless-N Card

The Dell DW1503 is a half-height Mini-PCIe wireless adapter built for select Dell laptops. It provides 802.11n connectivity through a PCI Express interface. The card carries Dell part number V91N8 and is supplied in new condition. It is intended as a direct replacement or upgrade for the factory-installed wireless module in compatible systems.

Compatibility and Limits

This card fits specific Inspiron models including the M511R, M5010, 14R (N4110), 17R (N7110), M4040, M5040, N4050, N5040 and N5050. It also supports Vostro 1440, 1450, 1540 and 1550 notebooks. Buyers with laptops outside this listed range should look elsewhere, as the card will not physically fit or function in unsupported chassis. Systems requiring newer wireless standards or different form factors cannot use this module.

Capacity and Headroom

The adapter delivers Wireless-N performance suitable for everyday web browsing, email and standard-definition streaming on Windows 7 or Windows XP. It handles typical home and office network traffic within the 802.11n specification. Bandwidth-intensive tasks such as high-definition video streaming or large file transfers may exceed the comfortable throughput of this draft-N implementation. The half-height design limits use to slots accepting that specific form factor.
