Product identity

The Linksys WPC54GX4 is a CardBus wireless adapter that brings 802.11b/g connectivity to notebooks through a 32-bit slot. It targets owners of older laptops running Windows 2000 or XP who need a simple way to join existing wireless networks.

Interface limits

The adapter plugs into a 32-bit CardBus slot and tops out at 240 Mbps using proprietary ACE compression on top of the 802.11g baseline. Real-world throughput will fall well below that peak, and the hardware cannot connect to 802.11n, ac or ax networks.

Capacity and headroom

The card supports WPA, WPA2, 802.1x and 64/128-bit WEP encryption for secured networks. MIMO antenna diversity extends usable range up to three times farther than a single-radio 802.11g device, but the 240 Mbps link rate is a theoretical maximum that typical conditions will not sustain.

Questions about this item

Which capacity or version of the WPC54GX4 should I choose?

The WPC54GX4 is offered as a single 240Mbps Wireless-G CardBus adapter; there are no alternative capacities or versions to select.

What does the 240Mbps headline figure mean once the card is installed in my laptop?

The 240Mbps rate is achieved by overlaying two Wireless-G radios using MIMO technology; actual throughput will be lower and depends on signal quality, distance and interference.

What does the 32-bit CardBus interface cap in practice?

The 32-bit CardBus slot provides ample bandwidth for the adapter's 240Mbps maximum data rate, so the wireless link remains the limiting factor.
