Intermittent Disconnects T3 time-out, CM1100 status and logs
Hi, I have a CM1100 modem, about 3 months out of the box. I am experiencing time outs. The all modem lights stay connected. Only quick but noticeable drops. There are no coaxial splitters inside or the outside box. I remember the team of technicians that setup my service say that my house is bit far from the node. Any recommendations would be appreciated. Thank you.

Intermittent Connectivity
My internet randomly drops, most often when doing high bandwidth activities such as streaming or playing online games. My modem has been reset by two different Cox representatives but not fixed, I have had zero problem with Cox for the entire year living in this apartment (Phx, AZ) until last night. Here is my conversation with a Cox representative that did not fix my problem but merely offered and suggested "I upgrade my plan." In the 3 images, you can clearly see my connection issue happening. How do I solve this? https://imgur.com/a/rd2D7mM

Intermittent Connection cuts out every 10 minutes
My internet drops out every 10 minutes it seems. Power cycle continuously to fix but no help. On my second panoramic modem/router. This is probably going to make me switch back to ATT which I don’t want as the speeds are slower.

Intermittent disconnect at least once per hour
I get many messages from Cox online backup telling me that my connection has been lost, and if I'm on FB I see a message under chat telling me also that the connection has been lost. It reconnects immediately without me doing anythng, but this can't be right and I fear it may signs of something worse to come... I've always had problems when trying to stream anything on DirectTv or Chromecast, I think this constant disconnect/reconnect may be causing those problems. What are the first things that I should check and/or do?
