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.
