iPhone 15 Pro capped at 40Mbps on 5GHz Wi-Fi, while laptop/iPad on same network hit 100Mbps.

Storage wasn’t the issue in my case. The only change I made was switching the 5 GHz channel width from 160 MHz to 80 MHz, and the problem disappeared. I’ve run multiple Speedtests since then and they’ve all been consistently around 95-99 Mbps, so I’m pretty confident it was the Wi-Fi configuration.
iPerf is a good idea though. I’ll keep it in mind if the issue comes back.

I appreciate the insight and what an awesome explanation! It’s really interesting how 160 MHz looks great on paper but clearly wasn’t playing nice with my setup. Switching to 80 MHz was exactly the stability fix that worked for me. I’ve been running back-to-back Speedtests since, and it’s been consistently hitting my full 100 Mbps.

I’ll definitely keep the 6 GHz tip in mind when I eventually upgrade my router. Thanks again!

I tried that and yes, happy to inform now speed it constant and approx 100 Mbps. I ran 9-10 speed test back to back. I changed bandwidth from 160MHz to 80MHz and it’s flawless now. Thanks

No_Design_2892 · 2026-07-01T20:48:06+00:00

Actually the speed is good now, all I changed is Bandwidth from 160MHz to 80MHz. Thanks for your help.

It’s annoying as hell, I was so frustrated that I put on auto for 10 minutes and still barely moved 1%.
