Good Day, Plzz I need help to get the suitable driver for my blutooth , in my Inspiron 15R N5110 as it didn't work after installing OS win 8.1 , I tried many drivers even I tried " DW1702_W8_X01_A01_Setup-3K92G_ZPE " but I didn't find the file named "BtwMM.exe" as per the topic , but I found after extracting the following root : "C:\dell\drivers\3K92G\drivers\production\Windows8-x64\Bluetooth-Driver " without any exe file to run the setup, thanks in advance for your help .
