iPhone 15 Pro capped at 40Mbps on 5GHz Wi-Fi, while laptop/iPad on same network hit 100Mbps.
My iPhone 15 Pro is consistently seeing download speed ~40Mbps, while my laptop and iPad on the same 5GHz network are hitting 100Mbps.
I’ve already tried a clean install, updated to iOS 26.5.2, reset network settings, Force Restart, Power off.
Wi-Fi: 5GHz band, no VPN, iCloud Private Relay is off.
Device Info: iPhone 15 Pro, iOS 26.5.2.
I have already called Apple support and screen shared with them. They ran diagnostics and everything was good. I don’t understand why is it happening.
Is anyone going through the same issue? Thanks for your time.
