Ruth's sister RT3072 300Mbps Wi-Fi adapter

SKU CH-34H3-HJ0QP

A compact USB wireless adapter with an RT3072 chipset delivering up to 300 Mbps Wireless N speeds for desktop computers

  • Wireless N speed up to 300Mbps for smooth browsing
  • MIMO technology delivers 300Mbps transmission rates
  • CCA technology avoids channel conflicts for stable signal
  • WPS button enables quick secure setup
  • Supports 64/128-bit WEP, WPA/WPA2 encryption

RT3072 USB wireless adapter

This RT3072 USB wireless adapter adds Wi‑Fi to a desktop or laptop through a standard USB port. It uses a built‑in PCB antenna and supports wireless N speeds up to 300 Mbps under IEEE 802.11n, 802.11g and 802.11b. The device is powered from the USB connection and requires no external power supply. It is aimed at users who need a simple way to join an existing wireless network.

Suitable for basic connectivity.

The adapter suits home or office PCs running Windows 7, 8, 10, XP, Vista, Linux or Mac OS that only need web browsing, email or light streaming. It also works with older Windows CE 5.0 and 6.0 devices. Buyers who need faster throughput, dual‑band operation, external antenna options or support for newer Wi‑Fi standards should look at a different class of adapter.

300 Mbps wireless N rate is the deciding spec

The single figure that determines whether this part fits the task is the 300 Mbps maximum link rate under 802.11n with MIMO. If the target network runs at higher speeds or uses only the 5 GHz band, this adapter will not deliver the required performance. For networks limited to 802.11n at 300 Mbps, the RT3072 chipset provides a direct match.

Highlights

  • Wireless N speed up to 300Mbps for smooth browsing
  • MIMO technology delivers 300Mbps transmission rates
  • CCA technology avoids channel conflicts for stable signal
  • WPS button enables quick secure setup
  • Supports 64/128-bit WEP, WPA/WPA2 encryption

Questions about this item

Which RT3072 300Mbps adapter version should I choose?

This model is a single USB dongle with an RT3072 chipset and built-in PCB antenna; no other capacities or versions are offered for this item.

What does the 300Mbps rating mean in daily use?

It is the maximum link rate under the 802.11n standard using MIMO; actual throughput will be lower due to overhead, distance and interference.

Which USB interface does it use and what speed does that cap?

It plugs into a USB 2.0 port, so the bus limits practical throughput well below the 300Mbps wireless link rate.
