Wifi/LTE Antenna Strength - Data Points/Questions

[CASE01]

Curious if others are having the same issues I am and if it's hardware or software. When I connect my TM3 to my iPhone 11 Pro's Personal Hotspot I get MAX (3) WiFi Bars in Drivers Seat. I recently installed an eero Pro Wifi Mesh system and I'm once again getting MAX (3) WiFi Bars when the router isn't even 10-15 feet away. My iPhone 11 Pro gets full bars in the same location.

I cannot seem to get the full (4) Wifi Bars for the life of me

Also, I experience LTE intermittently dropping randomly from time to time while driving.

Do I have a faulty WiFi/LTE antenna or is this normal?

I believe the wifi antenna for the car is located in the passenger mirror, FYI. I also have a hotspot in the car and it gets 3-4 bars when I keep it in the console. LTE for me is fine however when on the road.

The wifi antenna is located between the A and B pillar on the piece above the window...
