    TO BE AVOIDED -- NOT COMPATIBLE WITH WINDOWS 10

    The product data sheet does not clearly state that this product is NOT windows 10 compatible.
    If you look on the ASUS website, you will find this information by reading the detailed datasheet. The ASUS marketing blabla, which LDLC has unfortunately adopted, simply states "windows compatible". The detailed data sheet on the ASUS website says "compatible with Windows XP, 7 and 8".

    LDLC service, perfect service, the product has been taken back.

    Product not compatible with Windows 10

    This product does not work properly under Windows 10. The driver is not really functional and there are problems connecting to the wifi network of my internet box (Freebox Revolution). I strongly advise against this product

    Mitigated

    It does what it asks, but I notice a certain resistance sometimes to want to connect to Wi-Fi points, software that freezes a little, software that can not connect to the wifi, in short it does the job, but sometimes you have to be patient.

    Not compatible with Windows 10

    Simple and efficient ASUS interface. Too bad it doesn't work properly with Windows10. Works well on other Windows versions (Vista). Good transmission and reception speed.

    good key when it works

    I have just switched to the freebox revolution and bought this key for my recent PC running windows 10 pro.
    I've just switched to the freebox revolution and bought this dongle for my recent PC running windows 10 pro. When it works it's fine but sometimes when it starts up it's not detected by the computer or it can't find the network.
    This happens to me once or twice a week.
    I'm not sure what the problem is, but I have to admit that I have no idea.
    It's not a Wifi problem with my box because my tablet connects fine
    I'm not sure what the problem is, but I'm sure it's not a problem.

    Big problems with this key

    Big problems with this key.
    I'm not sure if it's a compatibility problem between windows 10 and this key or if it's just this key that's bad.
    I can't figure out if it's a compatibility problem between windows 10 and this key or if it's just this key that is bad.
    Either way:
    - it convinced me that I don't like wifi
    - It convinced me to switch back to ubuntu.

    Perfect, nothing to complain about!

    Works very well on my tower with Windows 7. Where my old Netgear WN2000RPT was preventing me from watching streaming movies because of a bad signal, this problem is solved. Connects with my Chromecast and forward Ginguamp, remains to be seen with time.

    Correct

    Fast delivery, (I imagine by post)
    Very good condition product (no problem with the condition of the package)
    And replaces very well the PLC ! (which are 2 years old and do not allow me to enjoy the fiber)!
