Interface & Format

This coolline AR5B22 adapter uses a half-size Mini PCI-E slot and delivers 802.11 a/b/g/n wireless at up to 300 Mbps across 2.4 and 5 GHz bands. Bluetooth 4.0 is integrated on the same card. The module measures 30 by 265 mm.

Suitable Laptops & Exclusions

It fits Asus, Dell, Acer and Samsung notebooks that expose a standard Mini PCI-E interface. Buyers with Lenovo, IBM, ThinkPad or HP machines should look elsewhere because those vendors block the card via BIOS whitelist.

Deciding Specification

The half-size Mini PCI-E form factor is the single detail that determines fit; a full-size slot or an M.2 keyed connector will not accept this card. Verify the slot type before ordering.

Questions about this item

How do I install the half-size Mini PCI-E card and which antenna connectors are easily missed?

Insert the card at an angle into the half-size Mini PCI-E slot, secure it with the screw, then snap both U.FL antenna cables onto the two connectors on the card edge.

What maintenance will the AR5B22 need over time?

No scheduled maintenance is required; if wireless range drops, re-seat the antenna cables and clean the gold contacts with isopropyl alcohol.

What limit appears first during sustained high-throughput use?

The 300 Mbps 802.11n link ceiling is reached before the Mini PCI-E bus saturates, capping sustained throughput.
