I got my new S85D yesterday and am thrilled with everything so far except for this: despite driving around various parts of Houston where I know there to be reliable cell tower signals, I am getting very poor 3G reception. In fact it never got above two bars, and mostly was at no bars or one bar with the 3G indicator missing. I ended up using my phone's hotspot to get a connection strong enough to do anything. Also, the GPS frequently put me on a completely different road than I was really driving, and of course, gave me poor directions as a result. I am on the latest 6.2 firmware. My theory is that either these radios are bad or something is shielding their normal operation. I have seen some posts over here about poor 3G since 6.2 was applied, but none of them seem to be as severe as mine. Before I start working with Tesla service and end up having the hassle of taking my car in, do you all have any steps I should try? I did reboot the main panel but that did not seem to help. Thanks for any help you can provide.
