Internet connection repeatedly disconnects for brief periods
Every day at around 11:00am-11:30am I start to experience repeated disconnections from my internet. Each episode will last about 10 seconds and it recurs dozens of times every day. They seems to occur sporadically every few minutes or so and can occur several times per minute or 15+ minutes apart. I upgraded my Internet service package from 200 Mbps to 1000 Mbps and the problem continued. I had a service technician come to my house and he tested the network and couldn't find any problems. He switched out my xFi gateway with new equipment but the problem persisted. Most of the time the internet is working fine and I am getting the correct bandwidth/speed but these ~10 second interruptions cause me to lose connection to the video chat I rely on when working from home. I have tried restarting my gateway numerous times without any improvement. None of my cables/connections appear loose and, as I said, the Comcast technician could not find any problems. I am connected via Ethernet cable.
Here is an imgur album containing screenshots of my Downstream/Upstream channel values for my router/gateway and PingPlotter data documenting the disconnections:

Any help would be greatly appreciated. Thanks.
