How do I fix connection drop when Mirroring iPhone to MacBook Air?

I turned off VPN and it works flawlessly

Can confirm, the solution posted by jesor_ (splitting 2.4 ghz / 5 ghz / 6 ghz bands into other networks worked for me.

I forcibly closed the iPhone mirroring app and reopened it, and it started working again. Clearly, it’s a bug that Apple isn’t paying much attention to.

you really think it boils down to somthing my company is running in the background? i mean i had used it yesterday, in the office, for a full day it was working perfectly.

Were you in the office when it wasn't working?

so is there anything i can do to escalate it? can i open a support case to Apple? do i need to ask the IT team to open the support case on behaf of the company? where do i go from here?

Apple's going to be a dead end. Your IT team is your point of contact. The problem here is that managed computers typically have custom configuration and software installed that we don't have. Some of the things that we would suggest trying, like removing antivirus, you can't do.

The firewall is a configuration setting that seems to be causing lots of problems. Since it is turned off by default, and is known to be majorly buggy, that's the first thing to test. Another problem that people are reporting is the new setting for "rotate Wi-Fi address" in Sequoia. I don't think that would be a problem in your case since you said you aren't using a VPN and you turned off the firewall. But who knows? That's the problem with IT managed devices, best I can do is give you suggestions you can't try, and make random guesses that don't seem like they would help.

When I he,p other Mac users with wireless problems I always seem to think in wireless system Preferences changing the ‘Automatic’ seems to get confused when leave and come back! So I always tell them to change the Loction toggle and take of auto and creat you own network (like home or business or school) and everything will work better steadily! I always do the with every new Mac I use! So go ahead and change that name to custom name in Location toggle!

The jesor_ solution is correct, thank you! I compared the settings in two modems. By one the iphone mirroring worked, and with the other didn't work. The only difference was in the Wi-Fi Channel number. Only in certain channels it works. For me, in the 2.4GHz frequency, only Wifi-Channel 6 works, and in 5GHz frequency it worked only when I set the IEEE802.11 Mode on 802.11n and the Wifi-Channel on W52.

This worked for me exactly how you said, and I appreciate that you articulated how you came up with it, hopefully this issue gets fixed in future updates & I can turn the firewall back on. Thank you!

The jesor_ solution gave me good hint -> wireless configuration.

I am using Shaw/Rogers modem with Wifi-6 capability. Both my iPhone and Mac are using 6Ghz band, and the mirroring interrupts every 6 seconds. Then I turned off the 6G band, making both devices connect to 5G band, and the issue is gone.

Not only this is fixed, the continuity camera in wireless mode is working smoothly too between the 2 devices. With 6G band it was almost unusable.

oh and another update: weirdly when i leave my iPhone right next to my MacBook, on the right-hand side, iPhone mirroring works flawlessly, moment I keep it in my pocket or even 6 inches away from the MacBook I get that annoying "connection was interrupted dialog".

Do You think one of these apps might cause this issue?

Only you can say that by trying it again. I think disabling the firewall should be enough.

I just called the IT team

Ah, work computer. All bets are off. Ideally, they would have tested all of this a couple of months ago or blocked you from upgrading.

PS no firewalls and both are personal devices without any employer software security issues

yes , this happened when a ****** company like apple releases unpacked software and features . so simple
