Super slow wifi speed on my new iPhone 14 Pro

Using the same wifi access point (Amazon Eero 6+) and using the same speed test (Netflix fast.com) from the same distance (3 feet), my MacBook Pro M1 gets 620 Mbps download speed and is super fast and my new iPhone 14 Pro only 6 Mbps and is completely unusable. All the settings are the default (no difference), I disabled iCloud Private relay (no difference).

Why this happens? Should I send the device back to Apple service?
