As I anxiously await the 2018.10.4 firmware update from the mothership, I thought I would try (first time) a little snooping of the 802.11g wireless traffic between my Model S and home AP/router (Motorola SBG6850).
However, after monitoring for several hours, I noticed only a small amount of regular and repetitious traffic between the car and the AP - basically LAN protocol queries and responses (ARP and SSDP) between the router and the vehicle, with absolutely no traffic between my vehicle and the internet. I've tried a number of things, including rebooting the MCU, AP/router, streaming audio etc; I am able to see the car switch from LTE to 802.11 and lock there via the indicator icon on the top right of the MCU screen. However, based on my Wireshark captures, there is no traffic except ARP and SSDP. Consequently, I am thinking the preferred (and apparently exclusive) route for traffic between the mothership and my car is via cellular LTE/3G connectivity. Hence, my question for those with network/Model S experience, is this typical ?
If so when/how is the 802.11 mode used ?
