I've noticed that when traveling on I-10 my wireless Carplay goes out (console reports WiFi interference) as soon as the Marriott hotel at Corporate is in view. As I get closer to that building, the connection briefly restores, and then fails again as I get further away with the building still in view. Once that building is out sight, I have no issues.

That's very odd, WiFi's modulation scheme is more or less immune to far-field RF interference. Must be a hell of a signal. It "disappears" when you're close to the Marriot because at that point the building is blocking their transmission beam pattern, which from your description could be omnidirectional. I'm guessing about the omni part.

Follow the link below for FCC Consumer Complaints and file under the "Radio" section using the Marriott address. And, search for the FCC New Orleans office, call and see what they say. Search the Marriot address too for "FCC Licenses" and see if anything pops up.

Wish I could help more, good luck.

Thanks for your advice! Complaint submitted.

I'm not sure how wireless CarPlay works, WiFi or Bluetooth. The car reports WiFi interference, but I wouldn't be surprised to learn it's actually a bluetooth problem like others have reported issues with.

Unfortunately, it's not just a minor audio inconvenience as it causes the entire vehicle infotainment system to basically reboot. Music, navigation, rear seat video, phone calls, etc... all get interrupted. Hope this complaint gets me somewhere!

eta: Wireless CarPlay uses both the Bluetooth connection and a closed WiFi network to communicate with the phone. This allows both sufficient bandwidth for data exchange (WiFi) and sufficient control protocols to exchange commands with your phone (Bluetooth).Apr 28, 2021
