Hypothetically. I steal my intent from Comcast. DDR-WRT router, external antennas, xfinitywifi hotspot, and a spoofed MAC address thanks to a little knowledge of OUI and some patience (though I'm down to 1 MAC address - you literally have to brute force trial and error to discover ones that might work, and I never developed a script [I guess I could use curl] to figure out which ones bypass the login screen).
