Review: Linksys Max-Stream ​AC600 USB Adapter

If you have a computer that you want to add WiFi to, such as a desktop computer, so that you can place the computer wherever you want, or to upgrade a laptop with a slower WiFi adapter, the easiest way to add WiFi is to use a USB adapter. Today, I’m looking at the Linksys Max-Stream AC600 USB adapter which only works with Windows PCs ( Windows 7, Windows 8.1, Windows 10 operating systems only.  Windows 8 is not supported). Thus I had to borrow three Windows 10 laptops to conduct my tests. It’s a tiny USB adapter that supports everything up to 802.11 ac and occupies almost no space. It support both the 2.4 Ghz and 5 Ghz bands and supports MU-MIMO technology. More on that in a second.

Setup is easy:

  1. Pop the CD into your computer and run the setup application.
  2. Wait until you are prompted to plug the USB adapter into the computer.
  3. The drivers will get installed and the setup is done. Declare victory and have a beer.

Once installed, I was able to do some speed tests and I was able to figure out that this adapter maxes out at 400 Mbps when I tested this adapter with the Linksys Max-Steam AC5400 Router that I tested earlier this week. That’s acceptable given that these are USB adapters and as a result they have small antennas that limit the speeds that they are capable of. That was kind of interesting. But I went a step further. I wanted to find out if MU-MIMO really worked.

MU-MIMO works like this. Normally, each device on a WiFi network gets serviced one at time. MU-MIMO can service each device simultaneously. Clearly the latter is more efficient. To test this, I took three Windows 10 laptops with the AC600 adapter installed and started streaming three different 1080p videos from YouTube while I monitored the speed of the connections coming into the PCs. If MU-MIMO works, there should no stuttering of the videos. And that’s what exactly I saw. To make sure that this wasn’t a fluke, I used the built in 802.11 AC adapters that were built into the Windows 10 laptops which did not have MU-MIMO and I noted that the playback wasn’t nearly as smooth as stuttering was present on all the laptops from time to time. Is this a scientific test. No. But it is how the average user will tell if MU-MIMO is working or not. And it clearly works.

The Linksys Max-Stream AC600 USB adapter goes for $70 Canadian. It clearly a quick and easy way to get a PC or a laptop running Windows 802.11 ac and get MU-MIMO compatibility as bonus. Pair them with a MU-MIMO compatible router and you can really have a WiFi network that is capable of doing anything that you need it to.
