Wifi adapter disappears frequently

Hello there,

My laptop Wi-Fi drivers gets uninstalled automatically and does not work at all. I did run the dell diagnostics setup and installed the absent drivers of which more than half of them would not run. Now under the network adapters, neither it shows up the Wi-Fi driver that I can take assistance of troubleshooter. When I manually install the driver anyhow 555-BBCB : DW 1705 + BT4.0 [802.11bgn + B luetooth 4.0, 2.4 GHz, still it would disappear next time I start my laptop. 

Could you please help me with this ?
