$20 - $30 Networking and Wi-Fi

The Bottom Line: The Trendnet Wireless N-Draft PC Card seems like a compelling choice for your notebook PC, but we recommend waiting until the 802.11n spec is finalized before choosing an adapter.

Specs: 300 Mbps, 2.4 GHz, Wireless, CardBus

The Bottom Line: If you plan to sit within 10 feet of your WRT54GX4 router, you'll get satisfying throughput. But if you want an adapter that's faster than standard 802.11g, opt for the Belkin Pre-N, which shows more consistent performance.

Specs: 240 Mbps, 2.4 GHz, Wireless, CardBus

The Bottom Line: If your priorities don't include long-range connectivity, then by all means get the somewhat ironically named Netgear WPNT511 RangeMax 240 wireless notebook adapter for its record-breaking short-range speeds.

Specs: 240 Mbps, 2.4 GHz, Wireless, CardBus

The Bottom Line: The Belkin Wireless G Plus MIMO Notebook Card can't compete with another member of Belkin's wireless-adapter family, the Pre-N PC Card, but it compares decently with other pre-802.11n/MIMO adapters and kills the plain 11g competition.

Specs: 108 Mbps, 2.4 GHz, Wireless, CardBus

The Bottom Line: The Netgear WPN511 offers outstanding 802.11g and long-range speed when used with its router counterpart, the WPN824, but its performance suffers in mixed-mode environments.

Specs: 108 Mbps, 2.4 GHz, Wireless, CardBus

The Bottom Line: If you're already sold on the concept of VoIP in general and Skype in particular, the Actiontec Phone Wizard is a must-have device.

The Bottom Line: If you're looking for a PC Card adapter with great range, this is it.

Specs: 108 Mbps, 2.4 GHz, Wireless, CardBus

The Bottom Line: The WPC54GS offers a decent bang for the buck and is an excellent choice if you plan to use it with other Linksys SpeedBooster products.

Specs: 54 Mbps, 2.4 GHz, Wireless, CardBus

The Bottom Line: The Linksys WRT54GS is especially well suited for networks with both 802.11g and 802.11b connections.

Specs: Wireless router, 7.3 in x 7.9 in x 1.9 in, Wired, Wireless, Ethernet, HTTP, Telnet, External, 2.4 GHz, 1.1 lbs

The Bottom Line: The Siemens SpeedStream 2501 power-line USB adapter is a good solution for networking through USB connections, but it's not as fast as power-line Ethernet adapters we've tested.

Specs: 14 Mbps, Wired, USB
