Genuine Dell OEM half mini Wi-Fi card

This is a genuine Dell OEM half mini card built around the Atheros AR9285 controller. It fits the listed Inspiron models including the 5521, N5010, M5030 and N5030. The PCI Express interface provides a direct connection for wireless networking on supported laptops.

Sustained 2.4 GHz throughput behaviour

The adapter operates on the 2.4 GHz band with support for IEEE 802.11a, b, g and n standards up to 270 Mbps. Under continuous load it maintains the draft-N link without dropping to legacy rates. WPA and WPA2 pre-authentication keep the session secure during extended transfers.

Thermal and power profile in normal use

The half mini form factor draws modest power from the PCI Express slot and runs cool inside the laptop chassis. No active cooling is required and the card produces no audible noise. Power consumption stays low during typical browsing and streaming on Windows 7 or Vista 32-bit and 64-bit systems.

Questions about this item

Does the Atheros AR9285 card run hot or draw much power when the laptop is on all day?

It is a low-power PCIe Half Mini Card designed for 2.4 GHz 802.11n operation; typical draw is well within the slot budget and does not require extra cooling.

My Inspiron N5030 has the half-height mini-card slot — is anything else needed to install this 2P1GR adapter?

The card fits the factory PCIe Half Mini Card slot; you only need the two antenna cables already routed in the chassis and a supported Windows 7 32-bit, 64-bit or Vista 32-bit driver.

Will this 802.11n 270 Mbps adapter work reliably alongside the older 802.11g hardware in my home network?

Yes, it supports IEEE 802.11b/g/n quad-mode on the 2.4 GHz band, so it negotiates the highest common rate with legacy 11g or 11b devices automatically.
