Buffalo WiFi Adapter USB

Specifications
The AC866 is a dual-band adapter, capable of up to a theoretical 300 Mbps at the 2.4GHz band and up to 866Mbps at the 5 GHz band. It's a 2x2 adapter supporting double spatial streams, whereas the router is a more-powerful 3x3, triple-stream device that can support up to 1300 Mbps on the 5GHz band and 450Mbps at 2.4 GHz. The AC866 is not quite the ultimate wireless adapter for the AirStation AC1750, but pairing it with this router provides decent performance and range.

The adapter supports WPS (Wi-Fi Protected Setup) and Buffalo's own AirStation One-Touch Secure Setup for connecting to a Buffalo router. WPA2, WPA-PSK (AES, TKIP) and 124/64-bit WEP. Windows 8, 7, Vista and XP (64- and 32-bit versions) are supported.

The device is a bit thicker than most USB sticks, measuring 0.59 by 1.22 by 3.66 inches (HWD) and weighing just over an ounce.

Only USB 2.0 is supported. I've seen the best wireless adapter performance from adapters that can connect to USB 3.0 ports. The slower speed of USB 2.0 seems to hinder throughput rates a bit when compared to USB 3.0 wireless adapters.

The adapter ships with a quick setup guide, USB extension cable, and a setup disc containing drivers, product manual, and a client manager utility.

Installing the AC866
The setup utility on the disc, gives the option of installing or not installing an available wireless client manager along with the drivers. This is a big plus for me—I have tested wireless adapters that force you to install the vendor's proprietary wireless utility. I find wireless managers that take over wireless networking settings in Windows can cause issues with the adapters and connecting to wireless networks. I prefer simply letting Windows handle Wi-Fi connection.

While I was glad I wasn't forced to use Buffalo's wireless client manager, the setup process was not without some hassle: During setup I kept receiving a pop-up alert asking me to confirm if I really wanted to install a file as files were being loaded to install the drivers. It was a fairly lengthy installation process, so there were quite a few files to confirm. And I kept getting asked to confirm individual files to install, even after checking off the setting "Always trust software from Buffalo."

The problem is not necessarily with Buffalo's software. It could very well be a Windows issue, though I routinely install wireless adapters on this particular Windows PC and have never had to constantly confirm files to install.

This was not the only odd behavior I observed while installing the AC866. Once installation completed, the adapter was placed and remained in a disabled state when I viewed it in Windows network settings. Now, I had disabled the on-board wireless adapter as I do whenever installing a USB adapter. A right- click on the Buffalo adapter icon refused to place the adapter in an enabled state. I was only able to enable the device after reseating it my laptop's USB port.

Performance Testing
The AC866's performance in the 2.4 GHz band was pretty much on par with another USB 11ac wireless adapter I recently tested, Netgear's 802.11ac A62000 Wi-Fi Adapter">. However, Buffalo's adapter fared better in 11ac mode: reaching 124 Mbps versus Netgear's 74 Mbps at a testing distance of 15 feet.
