Tethering using iPhone hotspot
I do not have wifi connection at a remote location but do have 5G service. When connecting my iPhone to the internet using Speedtest, my download speed is about 100Mbps. When I connect my MacBook Pro to the iPhone hotspot (by direct cable, USB or by WiFi), Speedtest reports my MacBook download speed as 0.5 Mbps! It is admissibly slow. I've turned off all background app refreshing on the iPhone and reset network settings. Any ideas are appreciated.
iPhone 12 mini, iOS 15
