IOS 15.1.1 connected to Wi-Fi but “no internet connection”

I believe I found the fix... go to wifi settings> find your network>click (i)-info button>set proxy to automatic-DONT FORGET TO SAVE>then go to DNS settings>choose Manual>delete current setting>add new DNS 8.8.8.8

I hope this works for you, I tried at least 20 different fixes.

Good luck!

I'm also having issues with my 13 Pro Max, in my case my wifi works fine until I lock the device. After staying locked for around 10-15 minutes I'll go to use the phone and I'll see the wifi icon as if I'm connected and have internet but also get the "no internet connection", I have to turn off and on wifi for it to work. This has been an issue since day one after upgrading from an 11 Pro Max on ios 15 which had no issues.

Apple support couldn't help, they say I should take it to a repair center but I'm 100% positive it's a ios 15, 15.1 and 15.1.1 issue so I highly doubt the repair center will fix anything.

Here's to hoping ios 15.2 finally fixes this bug.

Im also having an issue connecting t my WIFI thru my TP Link Deco mesh. I just can’t get connected. While Im able to connect using my main router. It’s annoying coz I installed the mesh to extend my Wifi thru my home and after this failure of an update I cant. Apple please fix this fast

The only reason to bring it to an Apple shop is to have a certified technician confirm the problem and enter it into Apple's systems as a real non-hardware problem. So, if you can, please do visit an Apple service center and ask a technician to confirm that your problem is caused by iOS15 and not your devices.

Happened to us while traveling and using cell service. I think it has to do with the drivers on the network card or some bug they introduced. Try going to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings and then reconnect to your WiFi. It helped me from dropping constantly, but I just reset it an hour ago.

Support probably told you to try this already, and it's not an actual fix but may help mitigate dropping off the network. Try setting your Eero or whatever WiFi solution to 2.4Ghz channel only. The easy, temporary way would be to create a new WiFi SSID just for your phone, have it only use 2.4Ghz and connect to that. If that fails then set it to 5Ghz only and see if that works. 2.4 is slower, but it's better than dropping every few minutes/seconds. Apple has to be aware of it at this point, hopefully a hot fix is coming ASAP.

Today, both my iphone 13 pro max and ipad pro with ios 15.2 became unable to connect the internet through our Eero pro mesh system. Computer and other devices remain able to connect. iphone and ipad pro can connect through cox public wifi. Restarting iphone and ipad didn't help. resetting network settings on iphone didn't help. Am waiting for family to get off video calls to reset cable modem and eero syster.

Try turning wifi assist off, it is under the cellular, scroll to the bottom and turn off. I did this the same time I manually set the DNS. I did turn it back on after it started working and it seems to be fixed. Also, if you haven't, delete/forget all wifi connections, reset network connections>general>bottom of page Transfer or Reset iphone>Reset at bottom>select Network Reset ONLY. After turn off wifi assist> hard restart device (vol up, vol down, hold right button until apple comes up iphone XR-13), add wifi networks back, turn OFF all private wifi settings (private wifi & limit IP tracking) and see if it works. If it does you should be able to turn wifi assist back on. Hope that works. Another possibility is that your router has Access Controls on. If so turn that off and reset router. Access controls require permission to access router, the new IOS is changing so it isnt recognizing devices previously allowed. GOOD LUCK! I have been dealing with this for months and finally got it to work yesterday. Apple tech support was no help as everyone stated. They just pass the buck to the router or ISP.

I have the same issue. Ever since upgrading to IOS 15.1.1 my WIFI just constantly drops out or says cannot connect to network. It's really annoying.

Update. I reset my whole Deco WIFI mesh and that seems to have done the trick.
