    Ok,

    After having spent a day on the road with this laptop, I have come to the conclusion that Wifi is just utterly and un-repairably broken on this device. At my home wifi, I could only get 2.4 Ghz N to work with about 50 Mbit up and down, anything on 5 Ghz would slow to a crawl. At my work's 5 Ghz wireless, it actually worked pretty decently to my surprise, about 100 Mbit up/down. When I was trying to use it with my wireless hotspot though, it was pretty much unusable. Ping times for some reason would shoot up over 1-2 seconds (!) consistently for no apparent reason, where my MacBook would ping <150 msecs on the same network and much more consistently. I tried everything, from different drivers, disabling protocols in the Windows settings, switching my hotspot to 802.11g, nothing helped.

    Overall I have to say the experience with this device is really bad. I just notice now after going back to my MacBook how much faster webpages load and how much snappier everything is. I would have probably kept the device if not for the totally botched Wifi, but overall I don't think anybody can really be happy with the performance and experience of the device. Weight and form factor are nice, the screen is nice and bright, battery lift is good, but that's about it.

    The eMMC is so unbearably slow, it took several hours just to install Windows Creator update. And as somebody else already said, having bad Wifi on a mobile device in 2017 is absolutely inexcusable. This one going back for a refund.

    Well, I will be damned. I was about to send this thing back to the Microsoft Store. I turned it on to get my data off, and Windows Update installed two updates:

    Qualcomm Atheros Communications Inc. - Net - 4/13/2017 12:00:00 AM - 12.0.0.307
    Qualcomm Atheros Communications - Bluetooth - 3/22/2017 12:00:00 AM - 10.0.0.303

    I don't know if it will last yet, but Wifi seems to work a lot better now. It still won't connect to AC on my router, but speed on 5 Ghz N is much improved, it's running at least at 60 MBit up and down now. Surfing the web is also so much faster now, and ping times to websites are much lower and more consistent now.

    I may have to keep this thing after all!

    Can someone else confirm an improvement with Wifi after updating their drivers to the version above? Thanks

    EDIT: The driver above still doesn't seem to work well with my hotspot, but I stumbled across another driver that seems to have it all: http://support.lenovo.com/us/en/downloads/ds105865

    It works fine, even though it's for a different model of the card. Please try out this driver from Lenovo and report back.

    EDIT2: I just noticed the driver above is a Windows 7 driver. That is really bizarre, since it installs fine (you have to extract it and install it via device manager) and then it works fine. The performance difference it just insane. Don't know if it's just the Win 10 driver that is bad, or whether this Windows 7 driver doesn't enable some misguided power management, but it makes a night and day difference in my network.

    I'm glad you've found a workaround, but it doesn't say much for Microsoft, Asus or Broadcom/Qualcomm does it!! Frankly, this is 2017 not 1997 & wifi isn't new & this type of functionality shouldn't require any workarounds. At all.

    PLEASE Search for existing threads before posting a new one. Thanks.

    Couldn't agree more with you!!!

    But still good to have a working solution for the WiFi issues, it's a pretty usable travel companion now with working WiFi. Hope other people trying it out have the same success as me.

    In case anyone is still looking, there is another driver from Lenovo that worked best for me (the driver above was fast, but had trouble re-connecting after sleep). I believe this is the best driver for the device: Bluetooth NFA435 QCA9377-5 Driver for Windows 7 (32 & 64-bit) - Lenovo S405z. Make sure you install the Win 8.1 version from the package. After install, you can check the driver version in the device manager, it should be 11.0.0.601.

    To give you an idea of the immediate differences I see:

    11.0.0.601:
    Code:

    I must be doing something wrong. I've tried to install the various drivers specified in this thread with no success. Currently running the latest Microsoft updated ones mentioned by Konradsa however my average speed is about 25 - 30 MBPS with frequent drops to between 4 - 6 MBPS. This makes web browsing and streaming difficult.

    Hi,
    My wifi drops after I put the computer on stand by, and I am not able to pick any signal until I restart the computer.
    Has anyone had this same problem?
    I bought the Asus Mini T102HA used, so I don't know if this is causing the problem.
    But, in addition my clock's time is way off although I correct it (by setting it to automatic, and manually changing the time). Also, the stylus stops working for no reason and only begins working after I restart the computer. And finally, I am wondering if you would recommend downloading an antivus for this thing. I am using windows defender. I am afraid that if I download an antivirus it would overload the system as the processor is not that strong.
    Thank you : )
