4G signal strength?

[Indeo]

Anyone have issues with the 4G signal strength/antenna strength for the vehicle. I find that I totally lose signal when going into my garage, even though it’s just a single family home (not a concrete garage building). I also find my Sirius glitching every now and then. This is surprising since I never had problems with my 5 yo Audi or any other electronic devices for that matter.
Could there be a disconnected antenna or something?
