Gateway network sporadically dropping out

Over the past month or so Xfinity has been working on "improving performance in our area" (from text messages sent), flagging possible outage.  Then messages of resolution.  We have received a few of these messages, so not a one time thing.

After this work has been performed, the latest last week, while the network speed has improved, we now experience random drop of network speed and sometimes it seems the gateway is restarting on its own.

Very annoying to be on work conference call and having the network drop out, then come back.  This kind of fluctuation never happened before these latest rounds of work.

I have tried to flag this issue via the chat on the main page.   Customer support with x-finity is a nightmare.  It seems everyone I connect to is in another country reciting a script.   This latest issue I asked that the it be escalated.  Zero feedback.  It's stunning how bad it is to get issues addressed.  Phone support is worse.  I could literally hear chickens and roosters in the background of a real time call.

I am so close to switching to fiber.

Trying this forum to see if it yields any better results.
