USB 2.0 wireless adapter

The Tenda W311MA is a USB 2.0 wireless adapter that adds Wi-Fi to desktops or laptops. It supports IEEE 802.11b/g/n on the 2.4 GHz band with data rates up to 150Mbps. A 3.5dBi external antenna and 18dBm transmit power aim to improve reception over basic internal solutions. The compact white housing measures 39.1 x 17.2 x 12.6 mm.

Suitability and limits

This adapter suits users who need a simple way to connect an older PC to a 2.4 GHz network. It works with Windows 2000 and later on systems with a 733MHz CPU and 64MB memory. Buyers who require 5 GHz band support or speeds above 150Mbps should consider a different adapter. The USB 2.0 interface also limits maximum throughput compared to newer USB standards.

Deciding specification

The single specification that decides fit is the 150Mbps maximum wireless data rate on 2.4 GHz only. If your router provides dual-band AC or AX service, this adapter will not use the faster 5 GHz band. If you only have a legacy 2.4 GHz network and need basic connectivity, the rate is sufficient.

Questions about this item

Does the box include a driver CD or must I download the software separately?

The package contains the W311MA adapter and a CD-ROM with the user guide, so no separate download is required for initial setup.

The adapter is listed at 150Mbps — is that the practical throughput I will see on a 2.4GHz network?

150Mbps is the maximum physical-layer rate under IEEE 802.11n; real-world throughput will be lower due to overhead, signal quality and interference on the 2.4GHz band.

Will the 3.5dBi external antenna and 18dBm transmit power give noticeably better range than a basic internal-antenna dongle?

The 3.5dBi external antenna combined with 18dBm maximum transmit power provides stronger signal gain and improved reception compared with typical low-profile adapters using internal antennas.
