WiFi Speeds (iPhone 12 Pro Max)

What "toggling" are you referring to?

There isn't something inherently slow about Wi-Fi on the iPhone 12 models, there may be something slowing it on your network.

I don't have to do anything special and I get this speed on every Wi-Fi network I connect to.

The number one setting you should check is to make sure Wi-Fi assist is off.

Negative. I bought from Rogers in Canada. My wifi will throttle to a lower speed and then just stops working while still connected, so slightly different issue.

For 1 years, Apple provides the warranty not the phone carrier. All my replacements have come from Apple and I’ve had to deal with Apple directly.

My issue may be a little different. The wifi will stop working on mine. All will be good, then speed will throttle down and stop working(still connected with great wifi signal next to router). Rest of devices in house are fine. I’ve also experienced this issue at work numerous times, which is a different ISP and hardware compared to home.

I live over 4hrs from the closest Apple store, so Apple support just keeps sending me a new replacement homing it’ll magically cure the issue. I’m on my 3rd replacement and issue just happened today (1day ownership of this new replacement). Called Apple and they want to send me another replacement. Tried everything from turning off wifi assist, resetting network settings, resting entirely and keeping backup off to test, even had ISP change all equipment at home, nothing resolved the issue. Out of 5 Apple devices at home, I’m the only one with this issue...

Millions of people are using their iPhone 12 Pro Max with WiFi with zero issues, so it's much more likely to be your wireless access point/router that has an issue.

I just checked mine and got a result basically the same as that I posted in the post right above yours.

Have you checked to make sure your router is running the most recent firmware available for it?

The speed increased close to 4 times.I connected with 5 ghz version of my wifi router.It started working much better.Still it is 8 to 9 mbps less speed than my other devices such as MBA or Samsung Galaxy note 9. But much better than what I was getting previously

Mesh systems are particularly difficult to diagnose as one phone may be connecting to the router itself and another to the mesh point.

You may also want to check if band steering is enabled on your network.

The phone will connect to the strongest signal if given a choice. And 2.4 GHz has much greater range than 5 GHz. So it may be related to where you are relative to the router.

The most consistent connection speeds I get on the iPhone 12 Pro Max is when I connect through a WiFi extender I have at 5Ghz.

2.4GHz won’t go much over 100 anyway it’s not capable of more should be on 5GHz

I'm not sure what to tell you except to blame your router or something else in your network.

You may also want to double check that Wi-Fi Assist is off.

Check for firmware updates for your WiFi router/access point.

I certainly don't see that.

I have been seeing very inconsistent speeds on my iPhone 12 pro max, and every single time it is slower than my old phone (Samsung Z flip). I am getting at maximum speeds, less than half the speeds my other phone is running over wireless. There was a form online I looked up on how to troubleshoot my WiFi problems. Every troubleshooting step has been performed on my end with no gains. (Reconfigure DNS, Forget Wi-Fi network and join again, reset network settings, reboot router, update firmware on router, make sure you don’t have a VPN running, try toggling Wi-Fi assist on and off, etc).

I hope this issue is going to get fixed for everyone. But I have seen too many issues with this device since I got it. It’s going to be returned. Another unsuccessful iPhone for me 😁

I am on the iPhone 12 Pro and sitting next to me is an iPhone XS and iPhone 8. All three devices are connected 5g to the same AP and I am only getting around 25 mb/s with my iPhone 12 Pro versus 300+ mb/s on the XS and 8.

Apple has a problem and I am hearing more and more people having this issue.

I’m noticing slow WiFi on my 12 Pro too. On doing a speed test it’ll hit the max speed I have with my provider, but quickly drops by 75% and holds it there every time.

My 12 year old iMac, works Samsung A40 and laptop all hit max download speeds where ever they are in the house.

Also, connecting via mesh router. Logging onto it shows I’m connect at 5Ghz too

I have same issue with iphone 12.

I compared iphone 12 pro max & iphone 11 pro max side by side.

Both have same settings, same IOS ( tested both few times on ios14.2 and also latest 14.3 ). Private address turned off. Both connected to same router at 5 ghz.

Iphone 12pm consistently show weak wifi signal ( -70dbm ) and slower speed on speedtest.

Iphone 11pm at stronger signal ( -56dbm) and consistently faster speedtest than iphone 12.

Wifi AX Router is already at latest firmware.

I really don’t know what else to do than making a trip to apple store.
