U.S. Robotics USR5411 Wireless MaxG PC Card review: U.S. Robotics USR5411 Wireless MaxG PC Card

U.S. Robotics asserts that the MaxG PC Card can achieve a 125Mbps maximum throughput speed when used in conjunction with the Wireless MaxG Router. That's a few more Mbps than other adapters with speed-boosting enhancements, such as the 108Mbps Netgear WG511T . However, the higher speed rating didn't help the MaxG PC Card to outrun the WG511T in CNET Labs' maximum throughput tests: the MaxG PC Card earned a decent 37.5Mbps score, but the WG511T achieved a very fast 47.1Mbps time. At 24.2Mbps, the Hawking HWC54D ran slower than both--though the HWC54D's extremely long, 325-foot range is 125 feet more than what most adapters can manage, including the MaxG PC Card and the WG511T. Pre-MIMO devices such as the Belkin Pre-N PC Card exhibit more speed and longer range overall, though they also cost twice as much.

The MaxG PC Card ships with a standard two-year warranty that includes mail-in service and toll-free telephone support. Unfortunately, the phone lines are open during limited times only: 9 a.m. to 5 p.m., Monday through Friday, CT. You can try the U.S. Robotics support Web site for help, though the FAQ section of the site yielded no results when we conducted a search on the adapter's product name. Otherwise, the site lists about a dozen random troubleshooting tips for the card.
