AC600 dual-band USB Wi-Fi adapter

The sakose RTL8811 5B09 is a USB 2.0 wireless adapter that adds dual-band 802.11ac connectivity to a desktop or laptop. It operates on 2.4 GHz and 5 GHz bands with a maximum link rate of 600 Mbps combined. The Realtek 8811CU chipset handles the radio and baseband processing. A driver USB stick is included for systems without an optical drive.

Suits PCs needing a simple wireless upgrade

This adapter fits users who want to add Wi-Fi to a computer that lacks built-in wireless or needs dual-band support. It works with Windows XP through Windows 10. Buyers who need the higher throughput of USB 3.0 or 802.11ax should look at a different class of adapter. The internal 2 dBi antenna is fixed and cannot be replaced with a higher-gain option.

USB 2.0 interface caps real-world speed

The USB 2.0 host connection limits sustained data throughput to the bus maximum, so actual transfer rates will not reach the 150 Mbps or 433 Mbps PHY rates. This single specification decides whether the adapter meets the performance target for a given use case.

Questions about this item

Will the 5 dBi antenna need replacement or adjustment over time?

The adapter uses an internal 2 dBi antenna that is fixed in place, so there is no external antenna to replace or reposition.

What throughput limit appears first during sustained transfers on the 5 GHz band?

The 5 GHz link caps at 433 Mbps under the 802.11ac AC80 MCS9 rate, which is the highest specified speed for this adapter.

How much power does the RTL8811 draw when running continuously on USB 2.0?

Peak current is 220 mA at 5 V during transmit or receive, dropping to 180 mA in receive-only mode.
