Just be aware the our Teslas only connect via the older 2.4Ghz 802.11n, not the newer 5.0Ghz 802.11ac. Astounding to me since our 2015 P85D is otherwise state-of-the-art. Frustrating since I had to add a 2.4Ghz "n" speed access point to our 100% 5.0Ghz ac speed house.
I'm hoping Tesla will offer a 4GLTE upgrade that also offers 5.0Ghz "ac" WiFi... which will make the $500 upgrade worth it to me. In the interim we're living with 3G.
