Compact Wireless-N Adapter

The StarTech.com USB300WN2X2C adds IEEE 802.11n Wi-Fi to a desktop or laptop through a USB 2.0 port. Its external form factor measures .3 by .6 by .9 inches and weighs approximately .09 ounces. The adapter targets users who need basic wireless connectivity without installing an internal card. It ships as a single unit ready for immediate use.

Miniature Build With 2x2 Antennas

Despite its tiny footprint, the adapter houses a 2 Transmitter/2 Receiver antenna configuration that supports the 300 Mbps data rate. The USB 2.0 interface limits throughput to the bus maximum, so real-world speeds will reflect that constraint. No external antennas protrude, making it suitable for tight spaces behind a PC or alongside a laptop. The ISM band is supported while the UNII band is not.

300 Mbps 802.11n Throughput

The single specification that determines suitability is the 300 Mbps peak rate under the IEEE 802.11n standard. Backward compatibility covers 11 Mbps and 54 Mbps legacy modes. Security options include WEP at 64-128-bit, WPA and WPA2, plus WMM Quality of Service. Buyers who need multi-gigabit Wi-Fi or UNII band operation should select a different adapter.

Questions about this item

What practical throughput does the USB 2.0 interface cap the 300 Mbps 802.11n link at?

The USB 2.0 bus limits real-world throughput to well below the 300 Mbps radio rate; expect speeds closer to the 54 Mbps 802.11g ceiling.

What are the exact dimensions of the adapter so I can check clearance beside other ports?

The adapter measures .3 inches high, .6 inches wide and .9 inches deep, making it one of the smallest USB Wi-Fi adapters available.

What is the correct driver installation sequence to avoid the adapter staying in fallback mode?

Install the driver package before plugging the adapter in; inserting it first often leaves the device on the generic 11 Mbps 802.11b driver.
