==== ✅ What is it ====
* It’s a wireless network card. It lets a desktop computer connect to a Wi-Fi network without needing a wired Ethernet cable. pcupgrade.co.uk<ref>{{cite web|title=pcupgrade.co.uk|url=https://www.pcupgrade.co.uk/legacy-equipment/legacyexpansioncards/linksys-wmp54gs-54mb-wireless-pci-network-card-with-speedbooster-802-11g-retail/|publisher=pcupgrade.co.uk|access-date=2025-11-28}}</ref>
* It uses the 802.11g / 802.11b Wi-Fi standard (so up to ~ 54 Mbps under ideal conditions), operating on 2.4 GHz.

* The “SpeedBooster” feature (on some models) claims to improve real-world wireless performance — although by today’s standards, even “enhanced 802.11g” is very slow. pcupgrade.co.uk<ref>{{cite web|title=pcupgrade.co.uk|url=https://www.pcupgrade.co.uk/legacy-equipment/legacyexpansioncards/linksys-wmp54gs-54mb-wireless-pci-network-card-with-speedbooster-802-11g-retail/|publisher=pcupgrade.co.uk|access-date=2025-11-28}}</ref>
* Because it’s a PCI card (not PCI-Express or USB), it’s “old school” — many modern motherboards may not even have a PCI slot anymore.

So — if you plug this into a compatible desktop and install correct drivers, it gives that computer “Wi-Fi capability,” letting it connect to a wireless router — useful if you don’t want (or can’t) run Ethernet cable.
