Linux-Compatible USB Wireless Adapter

The AUTECH 650Mbps Dual Band USB Wi-Fi Adapter is a new wireless network accessory designed for desktop and laptop users who need a simple way to add or upgrade Wi-Fi connectivity. It connects via a standard USB port and supports a wide range of operating systems, including Linux kernels up to 6.2 and Windows 7 through 11. The included 5dBi antenna rotates 180 degrees to help optimise signal reception.

Suitable for Linux and Windows PCs needing

This adapter suits users running distributions such as Ubuntu, Debian, Mint, Kali, Raspberry Pi OS, and many others listed in the specifications, as well as Windows 11, 10, 8.1, 8, and 7. It works with dual-band AC routers and remains compatible with older wireless N, G, B, and A networks. Buyers who require Bluetooth connectivity or support for the 6 GHz band should look elsewhere.

650Mbps combined dual-band throughput

The single specification that decides fit is the maximum wireless speed: 433Mbps on the 5 GHz band and 200Mbps on the 2.4 GHz band, giving a combined 650Mbps rating. This throughput supports 4K video streaming and online gaming when paired with a compatible dual-band AC router. If your network demands higher link rates, this adapter will not meet that requirement.

Questions about this item

How do I install the 5dBi antenna and set its 180° rotation correctly?

Screw the 5dBi antenna onto the RP-SMA connector, then rotate it up to 180 degrees to point toward your router; the step often missed is tightening the joint so the angle holds under cable weight.

Will the 5dBi antenna or USB connector need replacement after extended use?

The 5dBi antenna is a passive component with no wear parts, and the USB plug is rated for standard insertion cycles; neither has a scheduled replacement interval.

What throughput limit appears first during a long 4K stream on the 5 GHz band?

The 5 GHz link caps at 433 Mbps, so sustained 4K streaming will hit that ceiling before the 650 Mbps aggregate rating becomes relevant.
