iOS 15.4 wifi issues

Hi,

First try this - If your iPhone, iPad, or iPod touch won't connect to a Wi-Fi network - Apple Support. If wont work Settings > General > Reset > Reset Network Settings. It will solve the issue.

If issue re-appears you may need to check modem settings and apply Recommended settings for Wi-Fi routers and access points - Apple Support on your modem.

I hope your issue gets solved.

I tried forgetting the network and adding it back. I get the blue check mark, but I don’t get the WiFi fan symbol in the top left of my screen, I just get the cellular connection bars. I don’t have any other nearby networks that I can try connecting with.

That's not the same thing as resetting your network settings. That's the next thing I'd try.

Hi,

If you can see that you are already connected to Wi-Fi via Wi-Fi settings on your iPhone it means you have connection, not being able to see Wi-Fi icon on status bar doesn’t mean that you don’t have Wi-Fi connection and sometimes you need to swipe down status bar and swipe up. It happens when your WiFi connection halts.

The correct instructions to Reset Network Settings are:

Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings

But this did not fix the problem of WiFi not working after upgrade of iPhone to 15.4.1

I don't have either of these problems. Perhaps you meant to respond to someone else.

Has anyone found a solution to this issue?? iPhone xr ios 15.4.1, cannot stay connected to the wifi at my work. I am able to stay connected on other wifi networks such as my home. I’ve tried: resetting network settings, turned wifi on/off, forgot network and reconnected, restarted the phone, turned off wifi calling and assist. I am going to unplug the work modem tonight but my hopes are low🤷🏻‍♂️

I changed WiFi from 2.4G to 5G and for some reason that worked. Maybe just a coincidence but nothing else worked, and it has not stopped working at 5G. I had the problem with two iPhones and it worked for both of them. My desktop iMac still runs fine on he 2.4G so does not seem to be a problem with the WiFi

Any updates? Tried all the suggestions above, and none worked.

iPhone and iPads do not stay connected to WiFi for more than 5 minutes at a time. Called Xfinity yesterday to make sure it wasn't an internet issue. They stated that they are aware of an issue with Apple devices having issues after the update that is unrelated to their equipment and that this is happening to lots of people. Their only suggestion was to keep "bugging" Apple for a fix.

What specific troubleshooting steps did you take?

Can you connect to other WiFi networks? Are you getting an error message? Have you tried resetting network settings?
