Comcast, like other ISPs have been known to throttle bandwidth. That is why you get lag. Bridging them to use a router isn't doing much, at least to my somewhat limited networking knowledge.
Yes, I would call Comcast about it and voice your concern.
This why I always buy my own network equipment and only send the MAC address of my modem to my ISP. When I started doing such, I noticed an immediate improvement in my online experiences and now I live by it.
Many people who have done such even report a dramtic increase in their network speeds.
Because you're leasing equipment from them, they have the ability to do whatever they want with your service. You're pretty much at their mercy.
If anything, while you're on the phone with Comcast, as them what are the network requirements in order for you to buy your own modem. Im pretty certain they will only say "It has to be DOCSIS 3 compliant"
