Not getting the advertised speed of 600 Mbps. Is this right ?

I upgraded to supposed get "up to 600 mbps".  I get spurts of 420, with the final results in the 350s.

 

Is this normal ?  Shouldn't we get what WAS ADVERTISED ?

 

I've been to get support - and the automated options keep resetting my modelm and gateway.  And then it drops you - whether using chat or phone call.

 

BTW, I'm using NETGEAR CM500V Cable Modem and was speedtesting with WIRED to it !  The product supposedlly can do up to 680 Mbps.

Per the Comcast website it’s not rated for your service, it doesn’t matter what the manufacturer rates it. What Comcast approves it for is what counts.
