iPhone 12 Pro max  I am experiencing the same issue. I just spent $1300 on this phone and my Oneplus7T triples its wifi speed. It’s ridiculous. I am currently next to my Netgear X6 R8000 Nighthawk router that has been amazing for every other device in my house. Weird thing is I only get over 80 mbps download on my 2.4ghz band. The router is Tri-band!!! And both 5G get under 20 MBPS. I ran an ookla speed test. Thought I’d share the results.  GHz Download: 98.9 MBPS  Upload: 76.0 MBPS  5GHz  Download: 1.24 MBPS (I’m lucky to get to 20 sometimes)  Upload: 14.3 MBPS On my laptop i get well over 200 mbps for both. I have the private setting turned off, set a static ip, changed the DNS, and reset the network without luck. I work in IT and this just boggles my mind. My $500 Oneplus should not be faster than a phone almost triple in price. How is it that only my 2.4GHZ connection gets okish speeds??? I thought I would share this with everyone because this is NOT getting the coverage it needs in the media. My brother has an iPhone 7 and just ran the same test and got 165 mbps download and 130 MBPS upload. My mind is doing cartwheels right now.
