Hi, I am having similar issues with my 12 pro Max. WiFi performance on my home router is extremely poor compared with my old phone (iPhone X). Download speeds on the old phone were 73Mbps down and 18Mbps up, whereas I only get 15Mbps down and 12Mbps up with the iPhone 12 Pro Max while standing in the same location, which is 5 feet from my router. Anywhere else in my house and all bets are off for the Pro Max, which barely manages to connect at all. i believe this is either an issue with the software/firmware of the Pro Max or a design flaw. IOS 14.3 has not resolved this either, so I hope Apple will address this in the next IOS update.Seems a bit unusual, try forgetting the network if you haven’t already, so Settings > WiFi > (i) > Forget this network. Then reboot your phone, reconnect, and see if the problem persists.
Always a good jumping off point for diagnosing problems.
If the problem persists after that, try Settings > General > Reset > Reset Network Settings. Then after the reboot, connect again and see how you get on.

Hi TrueBlou, I tried disabling 2.4Ghz and obtained the same results as previously on just the 5Ghz. I still suspect an issue with the iPhone 12 Pro Max.It’s strange that it’s inconsistent, I’m getting the full speed of my internet connection, 520 down, 36 up, consistently.
What WiFi are you using? 2.4Ghz, 5Ghz, AC, AX? Can you disable the 2.4Ghz in your router and see if it has an effect forcing it to a faster connection?
