Unstable Internet

Hi there,

I called Xfinity last year and upgraded my modem and subscription and got talked into some kind of upgrade with television (which I don't want). It was to fix the unstable internet. The problem has persisted. I have done the reboot sequences and calling Xfinity is such a problem. I am required to call, do the reboot sequence. Wait for a text. Call again, at which point it wants to perform the reboot sequence again instead of putting me through to a technician. Last year I did this and it took 3 days. I don't have that kind of time but at this point the Zoom calls getting dropped and the need to refresh devices over and over again are really disrupting life and work. 

Please let me know the fastest way to figure out what is going on and how to fix the problem WITHOUT working on this issue for 3 days without internet or with interrupted internet for repeated rebooting sequences. 

Thank you,

Stephanie
