I am using CPE 220 for internet sharing over a distance of nearly 100 m. The antenna are facing each other without any obstruction. The access-point and client are taking IP directly from the modem which has a 50 Mbps (fiber optic) connection. 

The internet speed is OK however, I am facing continuous disconnection of internet every few mins. The disconnection is very short however, it is noticeable when I am watching a video or browsing continuously. 

I installed a chrome extension for monitoring the connectivity and here are the results.
