Do you think they will mandate a switch over to Frontier only, or will the residents have the choice between Spectrum cable and Frontier WiFi/fiber?
That will be decided by the apartment management. You should ask if you are able to use another ISP, but it will probably be out of pocket.
If you work from home and need secure internet, Frontier bulk is not for you. My sister in law lives in an apartment complex with shared internet. When i did a scan of her network, I could see other people's devices on the network.
