Take the Comcast CPE, put wifi router in small faraday cage or open it up and unplug the antennas? Most of Silicon Valley is in the clutches of Comcast as well, unfortunately. It's 1.2gbps down / 35mbit up or ATT 768K DSL (and we'd have to pay to get phone lines) where I'm at. Of course, if you check the FCC Broadband Map, there are 7 providers here, with ATT showing 5gbps FTTH, which I've confirmed with their reps multiple times is not possible (there's no fiber on the poles in our backyard and they won't install any anytime soon). Apartments I've lived in around SV as well are also under the Comcast exclusive contract, with restrictions on any antennas or dishes, so the only other choice would be tethering an LTE or 5G device. We sold out the critical infrastructure of our country to investors and this is the result.
