    This is a pretty good adapter for the price, especially compared with other 11ac adapters out there. My only (minor) complaint is that newer drivers don't really seem to exist. Windows 8.1 includes some from mid-2013, and those on the included CD are only a few months newer. I haven't encountered any problems yet, but the lack of regularly updated software from either Monoprice or the OEM seems a bit like a bad omen that the chipset (Realtek 8812AU) might not be supported if problems should develop in the future, as they so often do.



    Of course, this is still a pretty new SKU, and only a small cause for unease but given the churn that can be expected with major upcoming operating system release(s), it'd be a lot more reassuring to know someone was maintaining the software to keep this thing running well into the future.

    PROS: - Surprisingly good build quality, much better than my reference point of a PID 8076 from a few years back

    - Better reception than PID 8076 (3-5 bars about 40 feet from the AP with a lot of other Wi-Fi networks in the area, vs. 1-2 bars from the 8076)

    - The USB extension cable/dock is nicely built, and actually pretty stable despite its small size

    CONS: - Current drivers aren't easy to find.

    - As you'd probably expect, the included "management" software is just silly. Unless you really need to use some of the super-obscure features, don't bother installing it: just point Windows' driver update dialog at the Driver\Windows\RTWLANU_Driver directory on the CD.

    AC1200 USB Dual Band Wireless Adapter
    This adapter worked great with a 11538 dual band AC1200 router at the far corner of the house until I upgraded my Mac from OSX 10.9 Mavericks to 10.10 Yosemite then the unit stopped working. RMA service was prompt, but the latest Mac driver Monoprice tech support could find was the one for 10.9, contrary to the description that says the adapter will work with "Mac OSX 10.4 or later." Anonymous from Seattle's unease now is my cause for distress.

    PROS: Adapter worked great with AC1200 router with previous Mac operating system. Prompt RMA service.

    CONS: Driver and therefore adapter won't work with current Mac operating system.

    Works, once drivers are installed. (Lubuntu 14.04)
    I first tried to follow the provided directions for driver installation on Linux, but failed. The instruction manual seems more geared towards a graphical installer for Mac or Windows. The Linux folder was all Greek to me (I'm just getting started with Linux) and after messing around in Terminal I looked for help online. This led me back to this page, where reviewer MW recommended "blog.danielscrivano installing-rtl8812au-on-linux-for-wireless-dual-band-usb-adapters/", and after a few Terminal commands the wifi adapter was working.

    PROS: Once you get the drivers, it works. Mine's currently about 50 feet from the router and hasn't cut out at all. It's only been in use a few days so far. Looks pretty futuristic on the desk.

    CONS: As a novice Linux user, I failed to install it using directions on the provided CD. Luckily, another monoprice customer (Thanks, MW!) posted helpful instructions. They require an ethernet connection, however. The adapter's antennae are bulky, so the extension cable is a must.

    Works great on Ubunutu 14.04
    I installed this on Ubuntu 14.04 and it works just great. I did not use the CD to install the drivers. I found instructions on a web site blog.danielscrivano installing-rtl8812au-on-linux-for-wireless-dual-band-usb-adapters/ so I needed a wired connection to get the drivers. I am using a computer that is at least 8 years old and I still get a great connection and good speed using the 5GHz band - 44MBps download and 12 MBps upload. The WiFi router is downstairs and this adapter is upstairs. I have experienced only one time when it would not connect. Ubuntu complained that it was out of range. I moved the unit and it came right up.

    PROS: Had no problems getting this to work once the drivers were installed. Take note that I did not use the CD.

    CONS: None so far

    Works great
    Works perfectly. Just as fast as any other 802.11ac device on my network. The extension cable is a huge plus.

    PROS: Works as advertised

    CONS: Can't seem to find the drivers on the internet, so the CD is necessary to install into Windows.

    Works, but not quite as described - in any case, a keeper
    I'm a Mac user

    Using in an old 32-bit original edition MacBook in OS X 10.6.8 to get some more performance than the built-in 802.11g Airport (54 Mbps spec) when used with Apple 802.11ac Airport Extreme WiFi router..

    It does improve performance markedly. Was getting about 20Mbps (Megabits/sec) with original, am now getting about 150-160Mbps, nice cheap upgrade. Will test on newer computer to see if USB 2 (nominally 480Mbps, but usually half that or less in real life) is throttling performance. Testing was done by transferring 760MB .mp4 file between 2 computers on my LAN, not over Internet, so the speed results are fairly pure.

    Install was not as given in the little booklet. The Icon for the connection in System Preferences Network is for Ethernet (double-ended arrow, not 4-bar fan like Airport), a bit disconcerting. The installer reported my AppleUSBEthernetHost.kext was improperly installed but it worked anyway.

    Testing: I turned off built-in Airport to ensure using the new one, and the pref pane showed it but it was inert. Starting the included Wireless AC Network Utility got me most of the way there, and typing and confirming the WiFi password for the router got me connected. It nicely named and saved the connection info including passwords. Be sure to keep this utility handy in your dock, as removing and reinserting the dongle or its USB cable connector requires running the utility again to reconnect. System Preferences may not be needed for setting up/reconnecting.

    Be nice if the included utility showed some basic info as seen when OPT-clicking the icon for the native Airport in the menubar: PHY mode (802.11b/g/n/ac), channel , transmit rate, width of band (20/40/80 MHz), and provided more controls so I could try to tune things, maybe correct mis-settings, but it does give a nice speed boost as is.

    BTW my Mac Mini situated 3-4 feet away typically gets 190-224 Mbps to the same router using 802.11n with an 80MHz channel when moving huge files.

    PROS: Inexpensive, gets decent speeds compared to 802.11g wifi in older computers
    Cable and stand are nice, keeping this alien visitor-looking device at a distance, and allowing placing it closer to the router by a few feet
    Utility uses only a bit of CPU power and can be quit after establishing connection
    Utility has room to remember a number of profiles (for different routers/passwords/locations)

    CONS: Not enough info availableabout the wifi channel characteristics nor controls to help select appropriate parameters. I don't know whether I'm running n or ac
    Installer a bit wonky as is the icon in 10.6.8 Network prefs
    Instructions don't quite match real-world installation experience

    AC1200 Wireless Dual Band USB Adapter works but sometimes has glitches
    I've been using this adapter with antennas for about a month, using mostly a Macbook Pro laptop with latest 10.9.5 version of Mavericks OS. I got the adapter because of problems connecting to G and N networks in a crowded wireless environment. Now I am successful in making stable and fast connections. However, the app needed on the Mac (which comes with the adapter) has problems where the app (and thus the connection) frequently (not always) crashes when the laptop wakes from sleep. This means that I need to manually restart the app to regain the network connection. Also, once I completely crashed the Mac OS by unplugging the USB adapter while the laptop was asleep. The Mac app has not been updated since fall 2013.



    I have also used the adapter a little bit with a Windows 7 laptop. There is not much documentation that I found, so it is a little confusing about what to do although I eventually got it working after installing. Seems to work OK although I'm not sure how it has affected my builtin wifi networking when I don't have the adapter connected. It seems like the builtin wifi is now working a little differently but I'm not sure. The adapter does improve my PC laptop connections in the difficult wifi environment where I use the PC ad Mac laptops.

    PROS: much improved reception for G and N networks

    CONS: sometimes the driver app has to be restarted on Mac OS X Mavericks 10.9.5

    Problems with the driver
    I've put this on two different machines. One was a laptop running Windows 7. The other was a desktop also running Windows 7.

    The laptop had another wi-fi driver and hardware installed. Immediately upon installing this extender the system hung on boot up. I was using the USB bus for this unit and so I would not expect a collision for the drivers. I backed this driver out and was fortunate enough to get the system back. I would have uninstalled the native wi-fi driver the laptop came with but I didn't want to risk it. The laptop was not the primary target for which I wanted to use the extender. So not a show stopper problem here.

    However the desktop that I put it on has also had problems. The system boots OK and some times gets a broad array of wi-fi signals in the area. The problem is that it is flaky. Way flaky!

    I've had some times when it has worked quite well for an hour or so. Then I've had times when the Windows 7 system seems to be having some kind of sporadic problem causing an audible and video "hiccuping" when booting up. After a time it works itself out.Then I may or may not see the wi-fi signals around me. Many times there is no signal at all. This desk top is a brand new system that has had no problems until this install. NETGEAR Nighthawk X4 AC2350 Smart Wi-Fi Router is the unit I'm trying to hook up to. Sometimes it gets connection but cannot see the internet. I'm going to re-install the driver because it seemed to work better when first installed. I'm will now uninstall and reinstall the unit again and see where I am at that point. The desktop has no other wi-fi unit to interfere with this unit. I'd sure want this unit to work I will report back.

    PROS: Seems to have good range.

    CONS: Driver problems. Serious to the point of not being usable.

    Response from Monoprice
    Hi Duane,

    Thank you for your review and truly sorry to hear about your experience with PID 11443. For troubleshooting purposes have you tried adjusting the antenna or testing in a different room? Another thing you can try is changing the Wi-Fi channel to see if the connection improves. Please let me know if anything changes after reinstalling the unit. Thank you in advance!

    Works Great at Great Cost
    My HTPC has a built-in dual band WiFi card. Unfortunately it doesn't have great reception. The 5GHZ band was so weak as to unusable. I saw this USB Dual Band adapter from Monoprice & decided to give it a try especially since the price was so low. I was very impressed with the quality of construction. With the included extension/stand & external antennas the number of available wifi locations more than doubled indicating a significant increase in sensitivity.

    PROS: Good construction
    Great performance
    Included base/extender stand allowing best placement

    CONS: None found

    AC1200 Wireless Dual Band USB Adapter
    My USB modem is on 15 feet from my computer so I didn't think this would make that much of a difference.

    To my surprise it did!

    PROS: As soon as I plugged it in I noticed the difference. I work from home quite often and for the price this was just what I was looking for.

    CONS: Have not experienced any cons yet
