In this case to isolate the issue further could you please help us with few more details 

Your current speed plan and is the issue is only on wifi connected device or even with direct connection?

If on wifi, is the issue happening on devices connected to 2.4 or 5G?

Thank you for responding!  
 

My Spectrum app show I have 1 Gig internet although I did request a reduction to 500 Mbps because I continue to have issues. 
 

I have 3 TVs connected through a router via Ethernet cable and they buffer often. Not sure how to test the speed of that connection 

my iPhone is connected via 5g and has connectivity issues. Buffering and drops occasionally 

my computer is connected via 2.4g and this is where I notice it the most. Video calls have poor connectivity throughout the day and internet drops  I believe I notice it more because I m on it for 8-9 hours straight as opposed to shorter periods on my phone

Since you are experiencing intermittent internet connections on both the 2.4G and 5G networks, I would suggest changing the Wi-Fi channels and monitoring them for the next 24 hours.
