I've used several of these PCI network cards to connect a Desktop PC to a wireless network.
Although this model can connect at 802.11g 54mbps and backwards (b, a), it still offers a decent speed and more importantly reliable and solid connection so long as your router has a good range.
I have found that even when the signal strength isn't the best, the Cisco Aironet card and its ariel will connect where other cheaper adapters won't.
It also has a length of cable for the ariel (which has a stand to sit on a desktop or where ever). Other cards have the ariel connected directly to the card itself and I've found that sometimes does offer the best chance of getting the strongest wireless signal.
Components and built quality, as you'd expect with Cisco, are high quality. Installation is straight forward, just a case of popping in the driver disc to install.
If you want to be sure you won't have issues connecting to your wireless network, I'd recommend this and other Cisco adapters.
The Cisco Aironet IEEE 802.11a/b/g Wireless PCI Adapter provides high-performance 54 Mbps connectivity in the 2.4 and 5 GHz bands. Whether configured to support single 802.11b coverage, single 802.11g coverage, single 802.11a coverage, dual-mode 802.11a/g coverage or tri-mode 802.11a/b/g coverage, the Cisco Aironet 802.11a/b/g Wireless PCI Adapter is Wi-Fi compliant and combines the freedom of wireless connectivity with the performance, security, and manageability that businesses require.
The low-profile form factor and two-meter cable length provide significant flexibility for installation in low-profile devices, such as slim desktops and point-of-sale (POS) devices. For versatility, both a low profile and a standard profile bracket frame are included with the adapter. The attached dual-band 2.4/5 GHz 1 dBi effective gain antenna has a two-meter cable allowing for optimal placement and maximum performance.
