Wireless adapter for Lenovo laptops

The coolline BCM943228HMB adds dual-band Wi-Fi and Bluetooth 4.0 to compatible Lenovo notebooks through a Mini PCI-E slot. It supports 802.11a/b/g/n networks on both 2.4 GHz and 5 GHz bands with speeds up to 300 Mbps. The card carries FRU 04W3763 and matches the factory part used in several ThinkPad and IdeaPad models.

Fits listed Lenovo models only

This adapter suits owners of E130, E135, E330, E335, E430, E431, E435, E445, E530, E531, E535, E545, S230u, S430, S431, S531, B430, T430u, X131e or Y510p laptops that have a free Mini PCI-E slot and whitelist this FRU. Buyers with other brands, newer laptops using M.2 Key E slots, or systems that block unauthorised cards should look elsewhere.

Mini PCI-E interface decides compatibility

The card uses a Mini PCI-E edge connector, not the newer M.2 Key E form factor found in most current laptops. If your service manual specifies Mini PCI-E and lists FRU 04W3763 or BCM943228HMB, this is the correct part; otherwise it will not fit or be recognised.

Questions about this item

How do I install the BCM943228HMB Mini PCI-E card in my Lenovo E430 and what step is often missed?

Insert the card into the Mini PCI-E slot at a 30-degree angle, press down until the clips click, then attach both antenna cables to the MAIN and AUX connectors — the step most often missed is connecting both cables for dual-band 2.4Ghz and 5Ghz operation.

What maintenance or replacement will the BCM943228HMB need over time?

The card itself has no moving parts and requires no scheduled maintenance; replacement is only needed if the hardware fails or if you upgrade to a newer Wi-Fi standard beyond 802.11n.

What performance limit appears first during sustained heavy transfers on the BCM943228HMB?

The 300Mbps PHY-rate ceiling of the 802.11n radio is the first bottleneck; real-world throughput will plateau well below that figure during continuous high-load use.
