The Asus USB-AC56 unit is the fastest 802.11ac USB adaptor we have tested. It provides the best boost to your data rate at range and allows you to wander far from your router with your laptop while maintaining high data rates.

I use this device to replace my old wifi pci adaptor bought from Amazon (300Mbps 802.11n PC Desktop wireless N Wifi PCI Adapter). The old one has inconsistent connection and downloading speed, with spike lags and disconnection occasionally, which bothers me since I play online games.

With the exception of dropped connections, this is an amazing USB adapter. Connection drops happen once every 100 so times so its a small price to pay. My laptop was getting 5Mbps before, now it is around 110Mbps which is around what my service provider provides.

Very fast connection; Excellent speed retention; I get Ethernet-like speeds from 2 floors away; Excellent build quality

Connection drops at times; Dust magnet; Antenna detaches too easily

The only way to make it work is use some 3rd-party software that only kind of works. You will struggle to get this thing working at all. It doesn't do 5ghz wifi signal at all, no matter what sketchy websites you download files from, none of them will get 5ghz working.

Great product. I'm getting strong signals of my router.

Before I bought this I did a lot of research into this USB adapter and on another website like memory express it showed 4 stars in posted reviews. But on the memory express site it got bad reviews that I just decided to ignore and go and buy and try it out.

Basically nothing except for the materials that was used to make it

The software is slow,lagging, and glitchy; The original windows 7 software works way better but when It comes to the signal to stay connected, it can't connect to a faraway connection that my cell phone can connect to and my cell phone has similar antennas as this USB adapter

Recently we have done a few reviews on the emerging wireless AC technology but up until now those reviews have been limited to routers which merely allow access. Today we take a look at what may be one of the fastest ways to utilize your new wireless AC connection.

Asus has been trouncing the competition with respect to wireless routers , and now it has the fastest 802.11ac Wi-Fi adapter, too. The USB-AC56 is a fancy devil, with the same glossy black diamond-plate texture that Asus routers have.
