Interesting setup, so basically a USB-C connector to ethernet and then to the router for larger Wi-Fi radius?
I guess I'll have to block incoming calls somehow then.
Thats an option. My Synology RT2600AC can do this via the USB port. But device support is kinda limited from what I read up on it. But basically you just tether your phone to the router and you should get better WiFi reception. Like I said never tried it. But you still need to see what your hotspot/tethering data limits are. Most of the time they just deproritize your packets when you go over, but Im sure Verizon charges Comcast a lot of money for users who use a lot of data on their network. Im sure Comcast might have their own data policies.
