Inspiron 7559 Intel(R) Dual Band Wireless-AC 3165

I have had this laptop for little over 2 years and I have never been able to get more than 75-85 mbs on my router. I can get more than 200mbs on other dell laptops or other devices I have. I contacted support and they said that I need to contact my ISP to troubleshoot WiFi speed I figured that would be a waste of time considering all other devices get more than 200mbs with the exception of this one. I'm hoping someone can provide some help or guidance. in the past I had tried several drivers with no success thank you all in advance. If any more info is provided just ask
