We now have the Yoga 13 working properly.

  1. I bought my Yoga 13 recently, and after a few days usage the wlan dropped and also my bluetooth mouse started acting weird. I followed the steps above (which are in a very good level of detail by the way), but unfortunately they didn’t solve the problem. I continued with a couple of additional steps which solved my problem for the time being:

    #5 – Update the wlan and bluetooth driver
    Get driver from lenovo website.
    After that I needed to repeat the step #2 above for Wifi config.

    #6 – Get rid of mouse pointer flicker
    Disable the “RunSwUDB” service: Charms, Search for “local services” in Settings, right-mouse on RunSwUSB and select Properties, Stop and set its Startup Type to Disabled

    1. Started a new job this week – it’s April 2020 and I’ve had to dig out my old Lenovo to work from home as my new company can’t get laptops out to people quickly enough. I’d dumped it in a corner as it always had problems holding the WiFi connection and was going to trade it in for a new laptop, but never got round to it. Thanks to you Juhu, I’ve managed to get it working well and I now don’t have to sit right on top of the router – your advice works 7 years on….! Very grateful to all of these people on IT forums who share their info.

  2. Thanks!
    this was an enigma for me and this is the best answers so far before buying a whole new adaptor
