How to Resolve iPhone 16 Pro WiFi Connection Problems?

None of this stuff solved it for me but I found a *somewhat fix* that is not really satisfying but works.

Ref: https://community.ui.com/questions/Help-with-6Ghz-network-and-iPhone-16-Pro/e1afc842-a280-4bc7-883e-4dc7be1f27d5

I didn't get into the advanced solutions proposed on the linked page. However, what I found is that my office has slightly less perfect Wi-Fi than the rest of the house. I could connect to my wifi from the other rooms just fine. Once I stepped into my office (where all my laptops and other phones stay connected fine) the iPhone 16 would drop the network and be unable to reconnect.

So, I turned of 6hz and now it stays connected MOST OF THE TIME. All of my previous phones and laptops have no problem. This phone just has a super low tolerance for less-than-perfect wifi connections and I CAN'T BELIEVE THIS IS A PROBLEM. First iPhone in a decade and couldn't be more disappointed in something so simple.

I have similar issues with an iPhone 16 Pro on a Ubiquiti Dream Machine pro and a WiFi AP 7.

it will connect and work, but intermittently throughout the day data will stop working. I still have an IP and the router shows a connection. It shows a strong signal and small amounts of data flowing, but nothing on the phone works.

When I cycle WiFi on my phone, it reconnects again and works for another period of time before the issue returns an hour or so later.

Disabling Wi-Fi 6E mode for this network seems to resolve the issue. It’s been 2+ weeks without the issue returning with this feature off. That’s unacceptable though, I’m functionally using slower technology because of a bug in the phone.

Same regarding the VPN app. As soon as I deleted it, the phone connected to wifi.

Same issue - I deleted my VPN in settings and it immediately connected. I was able to reconnect to my VPN in the VPN app and everything seems to work.

This fixed it for me on my iPhone 16 Pro. Go to settings for your home wifi network and turn off the "private wifi address" option. Thanks pioneerprodj!

@G0atman- thank you!!! Settlings/General/VPN & Device Management/ delete all apps/settings WORKED!! Saved me from trashing the 16Pro

This worked for me too! "Forgot" my VPN config, it connected immediately. I think the issue is it was trying to use that configuration but hadn't yet downloaded the VPN app.

I had the same problem and following advice from other comments here, I removed all of my VPNs, even though none of them were switched on. The problem was instantly resolved.

vPN app was not activated and VPN showed “not connected”. So I hit “delete VPN” and WiFi immediately connected. Thanks for info.

Same issue. I turned off Private IP Address and it’s now connecting.

now get a a privacy warning label within the Settings page. Duh!

Hi all,

I had the same problem. Worked two days ago when I got it and quit just about two hours ago. I tried turning off the VPN and it seemed to solve the problem. Hope this helps.

I had the same problem. After trying Network reset etc. I delete the VPN App, which seemed to be the problem. Now it works.

If you are running a VPN turn it off. This is almost always the problem when people mention this issue.

If you have a VPN installed delete it and then you should have your WiFi connection sorted.

I turned off “Private WiFi Address” and it seems to be working instantly. Will see how long this lasts, hopefully an update can resolve this.
