What this adapter does

The Graviton RT5370-2DB is a USB wireless network adapter that adds 2.4 GHz Wi-Fi to a desktop or laptop. It uses the Ralink 5370 chip and an integrated 2 dBi antenna to deliver a maximum link rate of 150 Mbps. The device complies with the IEEE 802.11n draft 2.0 standard and supports 64-bit or 128-bit WEP as well as WPA, WPA2 and WPA-PSK/WPA2-PSK encryption. A WPS button enables quick secure setup.

Who it suits and who it does not

The adapter works with Windows 2000, XP, Vista, 7, 8, 10, Linux and macOS, making it a simple drop-in solution for older machines that lack built-in Wi-Fi. It is not suited for users who need 5 GHz band support or faster throughput than 150 Mbps. Buyers who require dual-band operation or higher data rates for heavy streaming should look at other options.

Behaviour under sustained load

The integrated 2 dBi antenna automatically avoids channel conflicts to maintain signal stability during extended sessions. In practice the link rate is shared between transmit and receive paths, so continuous large-file transfers or long gaming sessions will see throughput below the 150 Mbps ceiling. The plastic-and-metal housing has no active cooling, so prolonged heavy use may cause the adapter to warm up.

Questions about this item

What USB port does the RT5370-2DB adapter need on my computer?

The adapter plugs into any standard USB port on your computer and draws power directly from it, so no separate power supply is required.

Will the 150Mbps 2.4GHz adapter slow down my older 802.11g router?

It connects at up to 150Mbps on 2.4GHz and is backward compatible with 802.11g networks, so it works with older routers without forcing a speed reduction on other devices.

How can I confirm the Ralink 5370 chip is running at 150Mbps after setup?

Check the link speed in your operating system's network status or wireless utility; it should show a connection rate of 150Mbps when associated with an 802.11n access point.
