Finally figured out how to access WiFi for my Tesla in my condo's underground garage. First, I bought Eero Wifi extender for my Eero WiFi Mesh system. Placed it on my patio 4 stories above my car. Got faint signal but wouldn't connect. But I didn't give up! A few hours later it hit me. Why not place the extender near the Tesla in the garage? Viola! Reversing the procedure worked. The faint signal was enough to connect the extender to my main router and my Tesla now has WiFi in my street level condo garage. Wow, me, job well done! Were it a few feet off in either direction it still might not have worked. Despite my valiant effort, luck played a major role.
