but that's not everything, after i put back the drivers and bluetooth start working, my laptop will not connect to my-fi and i got to do the same thing (uninstall/install *any drivers) no matter what i got on, my bluetooth accesories will disconnect from time to time, and some times will not connect back, even after i close and open again the bluetooth, some time i need to uninstall the driver and install back to be able to use my mouse and keyboard on bluetooth. so long story short i upgraded my Intel N to and Intel AC 7260 (dual band wifi+bluetooth) but i still got alot of issues no matter what driver i got installed (got one set of drivers from lenovo site, one from intel and one from windows update). anywas, i was able to use it like that until this year, but now i got a new office and got myself a microsoft designer keyboard and a razer (wifi/bluetooth) mouse. i used for 3 years only wi-fi,cos if the bluetooth was enabled, my wi-fi signal will drop to 1/2 bar and the internet speed was at 5% from when the bluetooth was disabled. I have a lenovo yoga 2 pro from 2017, with an intel N 7260 wi-fi (only 2.4ghz)+bluetooth, that was so problematic.
i reach the boilling point with my problem. this complain will be posted on Lenovo, Intel and Microsoft forums. Hello everyone and sorry in advance for my bad english.
