Frequently dropped internet connection and slow speed

I have Xfinity 200mb plan and and a xfinity XB6-T new modem. My PC is hardwired directly to modem. No routers,. No VPN. I loose connection several times a day on PC as well as on all other devices connected on wifi. Also i dont get more than 70mb on my hardwired PC.. This has been happening for 4-5 months. 

 

Comcast techinician checked all wiring inside, outside, replaced modem and also checked signal at the box. All looks good. So he connected one cable from box in my backyard to modem directly but I still loose connection and speed has not improved. 

 

When i loose connection the white light on modem stay lit steady. I see lot of log entries when i loose cvonnection. Here is an example:
