Most Apple Devices (iPhone, Laptop, etc) not connecting to ATT Wifi Router

Hello @Zenjen, thanks for bringing this to our notice.

 We understand your concern and let’s get the help you need!

If your Apple phone won't connect to a Wi-Fi router, you can try the following steps1

• Make sure that your router is on and that you're within range.
• Make sure that Wi-Fi is on and that you can see your network.
• If asked, enter your Wi-Fi password.
• Check for issues with your Wi-Fi network.
• Check your cables and connections.
• Restart your phone.
• Reset your network settings by going to Settings > General > Reset > Reset Network Settings.

We recommend that you follow that troubleshooting steps:

• Unplug the power cord from the back of your gateway or modem. If you have: 
• An internal battery backup, remove it.
• DSL, unplug the phone cord from your modem or gateway.
• Wait 20 seconds.
• Put the internal battery back in if you have one. 
• Plug the power cord back in. If you have DSL service, reconnect the phone cord.
• Wait for the gateway or modem to restart and your Broadband light to turn solid green. This can take up to 10 minutes.

We already did all of the above to no avail. The devices see and say that they are connected to the WIFI, but when attempting to go online, check email, etc that uses an internet connection, it says "no internet connection" even thought the device states that we are signed into the WIFI network. Is there some security firewall? Some additional setting Apple device uses have to enter?

Hey again @Zenjen,

Hi.  I am having the same issues. My husband's iPhone phone won't connect to AT services. Been on the phone and at the AT physical store for
multiple days ni a row now. and still no help. No service. No connection. Iwent to the Apple store and they ran a diagnostic and there is nothing wrong
with the phone. Both companies blame each other and Iam left paying a bill to ATT for a phone that DOES NOT CONNECT to the ATT services that Ipay
for. Ialso bought the phone from ATT. Seems to me like ATT should upgrade or switch out the phone since according to them "only some phones" have
this issue. Somehow the customer is getting screwed and the two large corporations are not willing to take a minor loss to correct the issue that is not the
customer's problem. I would leave ATT but I owe $700 on my phone so that would be to my detriment as the consumer. I'm left with no good options. Is there anyone else having the same issues...and if ATT responds with factory reset, eSIM or contact Apple... will lose my mind.

Did your phone ever get internet service thru AT&T? I would Reset Network Settings and see what happens. A connection to WiFi doesn't automatically mean a connection to the internet. It's two-step process.

The problem is a connection to ATT celluar services not WiFi.  Everything possible has been reset.  ATT says it is the iPhone software update that we did a month ago.  Crazy!

@natelirog  Wait a minute, you said even tho you had a connection to WiFi, you could not connect to the internet. Did I misunderstand what the problem is? If you have cellular disabled can you connect to the internet?

I have an iPhone 12, running 17.4.1 and have no issues. I just turned off cellular and can connect to the internet via WiFi. Even placing my phone in Airplane Mode I can still connect via WiFi.

Have you contacted Apple. I doubt it's the phone but it can't hurt to check. Have you checked the settings for connecting to AT&T? Does it not work regardless of where you are at, home, on the road, etc?

Hi.  WiFi on the phone works fine.  It is in SOS mode.  This is an iPhone 13 running 17.4.1.  It just went into SOS mode randomly and will not connect to ATT cellular service.  The update to the latest software was done a while ago and the phone worked fine.  Yes, we went to Apple.  Apple did a diagnostic on the phone and said the phone is fine.  Was on the phone with ATT for four hours the following day and ATT says it is an Apple software issue.  Four days later...I'm still paying an ATT bill for an Apple phone I purchased at ATT and ATT can't help me.  They literally told me to "wait" because they are working on the issue but don't know when it will be resolved.  They made it sound like I am not the only one experiencing the problem.  So, here I am trying to figure out what others are doing about this "known" issue.  The phone does not connect to service at all.  It doesn't matter where I am.  I have done every factory resent, eSIM exchange, cleaning off the phone, resetting all of the settings and four days later and too many hours later...it still does not work.

@natelirog  A few others are experiencing the same issue so you are not alone. The fact that AT&T is blaming Apple is typical of how AT&T approaches a problem when nobody at CS Support has a clue or an answer. Did you purchase the phone thru AT&T or Apple (which is recommended along with AppleCare+)?

The phone was purchased through ATT.  They told us they can't give us a new phone even though the phone they sold us is not working...on their service.  It is hard to know who to blame because I am not a tech expert.  However, as a customer I bought the phone from ATT and my services are through ATT so it seems like ATT should offer support.  Instead, I was told to wait and be patient...and keep paying my bill and pay for the phone.
