How to Resolve iPhone 16 Pro WiFi Connection Problems?

Same issue works for about three days then Apple apps won't work. Not able to update any apps unless i switch back to 5g. iMessage's and facetime not working. all non-apple apps work fine unless i have to connect to an apple server like game center. started with iMessage's on apple support on 5g then after about an hour of rebooting still not working suggested that i try another Wi-Fi network to see if i can connect.

I’ve been having numerous connectivity issues with 16pro max. Never an issue before. Started with my Watch Ultra 1. I’ve reset it three times. It keeps losing connectivity. It also shows up twice in Bluetooth. Once as “connected” without the ℹ️ symbol. The other as not connected with the symbol. When this occurs, the watch won’t be connected to my iPhone. Find My won’t work nor fitness. A reset or restart works for a few days the. Stops again.

I then noticed drops regularly with my AirPods Pro while doing a fitness session. Today my Beats kept dropping as well.

All of this points to the phone being in common. Devices are all having issues. Could it be the WiFi? All of these devices, if I’m not mistaken, use two connections: Bluetooth AND WiFi. I’ll go ask Apple @ Genius Bar. I just reset network settings and removed VPN configurations, and the watch is now connected again. I’m sure I’ll be unable to reproduce the issue when they look but hoping this is already an issue they are aware of. Stay tuned…

You answered your own question. VPN is not only unnecessary on iPhone, but does in fact cause Wifi connectivity issues. The Genius Bar won't likely find anything wrong with your phone now that you have removed what was causing the issue in the first place.

Having a problem with my new iPhone 16, not recognizing local networks. I am able to connect to my home network, but when the phone searches for other networks, it doesn’t find any. I tried deleting my VPN with no luck. Any advice from anyone would be appreciated.

Ok…so I have the 2 different bands and the 2.4 works but it is extremely slow. My iPhone 16 Pro simply does not connect to the 5G band. I have tried literally everything and I do not use VPN. My internet provider is Century Link and they are of no help. Apple is of no help either. I was thinking about switching internet providers and going with Xfinity. Did you resolve your issue?

I am in the same boat. Tried everything! Even got a new iPhone 16 Pro. Nothing works. Last resort is to switch home internet providers and get a tech out here and tell them to figure this out. This is beyond frustrating!!!

Bit of a late reply, but the only more permanent solution I found was to restore my phone using my MacBook. Apparently at least some iPhone 16 Pro Max units shipped with a corrupted version of iOS 18. Restored the phone a couple weeks ago and reloaded iOS 18; it hasn’t given me problems since.

I'm having the same problem and wanted to give everyone here an update. There's no issue at all with my work's network/wifi. This is even more concerning to me, since it's clearly only affecting a certain type of network/wifi.

My wifi at home is Optimum with a 6E router. Tried everything (even turning off VPN etc.) and nothing worked.

I had the same issues. I booked an appointment with apple technician. We tried connecting to their wifi inside the store and it worked. I tried connecting on my sister’s home wifi and it worked too. It seems that the problem is our internet connection. I had to call my ISP and it is a know issue. They will replace my modem to a newer model that will be compatible with iphone 16 as it runs on wifi 6-7. So check with your internet service provider and check the compatibility of your modem or internet plan

Same problem. I can connect to my home wifi but then it just randomly disconnects and goes back to my phone data. I have auto connect turned on but every time I try connect back to the house wifi I have to put in the password EVERYTIME 🤯

I have been having the same problem. The one fix I have found is to forget the network and rejoin.

Settings/Wifi

Select Edit in the top right corner

Find the network and select information

Select Forget Network

Rejoin the Network

Hope this works for you.

Pretty ridiculous. We should all report the problem so they will pit out a fix.

Just bought two IPhone 16. Same problem. My phone would connect to the wifi but my wife's phone would not. I have a EERO mesh. I created a guest network on EERO and my run my wife's phone off that network. Solved the problem.

I have similar issues with my iPhone 16 Pro on iOS 18.1 (and 18.0 previous) connected to a Unifi UDM Pro and U7 Pro AP.

Connected to our home WIFI via WIFI7 all network activity stops intermittently a few times a day until I disable and re-enable WIFI on my phone. It will then continue to work for hours before it happens again. The Settings still show an IP address and as connected to WIFI. My router shows the device as still connected as well.

iPhone 12, 13, Google Pixel 8 and other WIFI devices have no issues connected to the same network (albeit WIFI6 or 5).

Very frustrating because you don't even know that you're dead in the water until you try and do something, then you cycle wifi and in flows all of the notifications that you missed.

Update: I went to the Apple Store, and they wiped it. I started with the previous version of iOS and started it as a new phone, not from a backup. It’s been working. I’ve just had to spend time tweaking the phone settings all over again. It’s a good way to start. I’m not downloading all the apps I don’t use again 😉.

16 promax is not connecting to our wifi, it's been a month trying everyday, seriously tired of the iphone problems, comin up new series of issues every year.. I am recently welcomed a higher priced Samsung, and super happy with it.. definitely suggested

I register all my devices on the router using the MAC address of each device (most secure set up) the new IOS does rotating MAC addressing (for security) which causes problems with router config - if it’s a home (trusted) network set a static MAC address and register it against the router - VPN work by registering a device if you have a rotating MAC address then this will tell the VPN it is not a registered device because the registered address is rotating - if your VPN is using device IP address to register - the new IOS does the same and rotates IP addresses to prevent tracking - My just opened 16PMax came up with network channel issue - then said cannot get on the network - once I rebooted the router and did all the Apple stuff to fix to no avail - I set the phone up manually using the trusted MAC address (static) and registered it against the router all worked fine … it is a poorly designed feature of the IOS that was introduced a while ago - supposed to help with security but is a pain unless u know how to circumvent - hope that helps (p.s. - the apple pages doesn’t give a solution it just blames external factors)
