So, we are sitting in southern Mass, about to leave for the Cape. This morning I did extensive testing using the Visible chip; Alone in my Google Pixel 4xl - download data speeds reached 100Mbps on LTE + 4G+ Verizon cell site that was nearby. Tethered my WIN10 laptop to my Google Pixel and data downloads were 5-6 Mbs. Put the Visible chip back in my MiFi 7700 Jetpack - tethered my laptopp to the MiFi and got the same 5-6 Mbs. Tethered my little router (GL.iNet GL-AR750S-Ext) - connected to the Wifi and got the same 5-6 Mbs. Turned on the MiFi Wifi and with both phone and laptop got the same 5 Mbs. Going to do more research how that data limit works.
Another setting I found on the Jetpack config was to enable GPS over WiFi for loacation. That solved my Google Maps "current loaction" stuff. Where I was getting some location out in the midwest, it is now accurate.
