Ios16.4.1 update no Wi-Fi or data connection

Hi Dazzaharv,

Thanks for posting in Apple Support Communities.

We understand that your Wi-Fi and cell data connections are not working. It sounds like you have no connection. You can address this with a few steps.

Restart your iPhone or iPad

Restart your device. If you're not sure how to do this, follow these steps to restart your iPhone or restart your iPad.

Check for a Carrier Settings update

To manually check for and install a carrier settings update:

1. Make sure that your device is connected to a Wi-Fi or cellular network.

2. Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.

3. To see the version of carrier settings on your device, tap Settings > General > About and look next to Carrier.

If you insert a new SIM card into your iPhone or iPad, you need to download the carrier settings for your new carrier.

Turn your cellular line off and back on

Go to Settings > Cellular and check to see if your cellular line is turned on. If your cellular line is off, turn it back on. Then check to see if you have service.

If you don't see your cellular line in Settings > Cellular, you should set up an eSIM or insert a physical SIM card. If you're using a physical SIM card, remove the SIM card and put it back in.

If your SIM card is damaged, doesn't fit in the SIM tray, or you transferred your physical SIM card from another device, ask your carrier for a new SIM card. 

Learn more about removing your iPhone SIM card or iPad SIM card.

Reset your Network Settings

Go to Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.

You can find these steps and more in If you see No Service, Searching, or SOS on your iPhone or iPad - Apple Support.

Regards.

Hi Dazzaharv,

You mentioned both Wi-Fi and cellular data are not working. In this case, since these internet connections come from two different sources, Wi-Fi router and cellular radio in your iPhone, it may be hardware related.

We'd advise to have your iPhone examined by a technician. This page has info about getting your iPhone serviced, including the options:

Make sure to back up your iPhone before you have your iPhone serviced:

Take care!

Well a new update today and instantly I find my Wi-Fi more reliable and dare I say slightly better than originally and my cell data is stable once again . Do I still need to take both my iPhones back to the shop for repair as per the suggestion that it is a hard ware issue . YOU HAD MY LOYALTY IN THE FACT I HAVE 2iphones My self my children have iPhones that’s five in my house WHEN DO WE GET YOUR LOYALTY and you start to be honest and up front taking back to the shop could have been costly who would have won YOU

My Iphone 11 was working perfectly up to a recent update and now keeps losing WiFi. I've been thru all the suggested 'fixes' - switrching it off for a few hours brought WiFi back but lost it again today. First Apple phone that everybody was praising!!!! Why fix somehing that's not broken? How long's this going to take?

Done all steps recommended and still both my work and personal iPhones suffer with Wi-Fi and data issue both happened after the update when is ther a new update to fix this

So both of my iPhones went wrong at exactly the same time immediately after the latest up date but there is a hardware problem dose that mean the last update has broken both my iPhones ?

And everyone one else’s after they done a update

I had the same problem, They shipped me a brand new phone.... Same issue its the update for sure.

if You use a VPN, try settings, General, VPN management and disable your vpn. Then restart.

or uninstall the VPN software and restart the phone. If the internet works then reinstall the vpn

Wow, this actually worked for me. thanks!

Restarting my sons iPhone 12 mini worked after update and could not connect to 5g after update but restarting it works
