Compact USB 2.0 Wi-Fi Adapter

The Relper-Lineso RLP-3505B is a compact USB 2.0 wireless adapter that adds 802.11n connectivity to desktops or laptops. It operates on the 2.4 GHz band with data rates up to 300 Mbps and includes an internal antenna for a low-profile fit. The device draws power directly from the USB port and supports Windows 7 through 10 as well as Linux 2.4 or later.

Home and Office Users Needing Basic Wireless

This adapter suits users who need a simple way to join a 2.4 GHz network for web browsing, email or streaming at modest speeds. It is not for buyers who require 5 GHz band support, 802.11ac or ax speeds, or a detachable high-gain antenna for long-range links. Gamers and heavy downloaders needing low latency or throughput above 300 Mbps should look at higher-specification hardware.

300 Mbps 802.11n Speed Rating

The single specification that decides fit is the 300 Mbps maximum PHY rate under the 802.11n standard on the 2.4 GHz band. If your router and internet plan deliver higher speeds, or if you need dual-band operation, this adapter will bottleneck the connection. Match the adapter's 300 Mbps ceiling to your actual network requirements before purchasing.

Questions about this item

What does the 300 Mbps wireless rate mean once the adapter is plugged into a real computer?

The 300 Mbps figure is the maximum PHY rate under IEEE 802.11n with a 40 MHz channel. Actual throughput is lower due to protocol overhead, signal quality and the USB 2.0 host controller.

Which interface standard does the adapter use and what does it cap in practice?

It connects via USB 2.0. The bus can carry the wireless link, but real-world speed is limited by the USB 2.0 bulk-endpoint bandwidth and driver efficiency.

What does the adapter physically need to fit or mount?

A single USB Type-A port. The nano-sized body sits almost flush with the port, so it clears laptop lids and tight spaces without a separate bracket or antenna.
