Half-height Mini PCIe combo card
The Dell DW1703 combines Wi-Fi and Bluetooth 4.0 on a single half-height Mini PCI Express card. It uses an Atheros chipset and operates on the 2.4 GHz band with a maximum data rate of 150 Mbps under the 802.11 b/g/n standards. The card is supplied new and carries Dell part number FXP0D.
Fits most half-size Mini PCIe slots except Lenovo
This adapter suits owners of compatible Dell Inspiron models such as the 15 3521 who need a direct replacement for a failed or missing wireless card. It will not work in laptops that use a whitelist blocking third-party Mini PCIe cards, notably IBM, Lenovo and HP or Compaq systems. Buyers with those brands should look elsewhere.
Requires a half-size Mini PCIe slot
The decisive specification is the half-height Mini PCI Express form factor; the card will not fit full-height or M.2 Key E slots. Verify that the target laptop exposes a half-size Mini PCIe connector and does not enforce a firmware whitelist before purchase.

Questions about this item
How much heat or noise does the DW1703 card add when the laptop runs all day?
The DW1703 is a passive half-height Mini PCI-E card with no fan, so it adds no audible noise and negligible heat during continuous use.
What slot must my laptop already have for this AR5B225 adapter to work?
Your laptop needs a free half-size Mini PCI Express slot; the card will not fit full-size or M.2 key slots.
Will the AR5B225 coexist with an older 802.11g Wi-Fi card I keep in another slot?
Yes, the DW1703 operates on the 2.4 GHz band using 802.11 b/g/n, so it can run alongside a legacy 802.11g card without conflict.
