Your iphone and mac must be on the same wifi network

I had this issue until I signed out of iCloud on all devices and then signed back in. For whatever reason it then started working across all devices in its entirety. This advice was taken from an Engadget article suggesting people are having issues with Continuity/Handoff.

So yes, sign out of iCloud on all devices, sign back in and see what happens.

After experiencing this glitch myself the fix was to sign out of Facetime and sign back in. Remember, the phone calls work through Facetime so that was my clue. Signing out of iCloud is a pain because it stops and deletes syncing and so forth. Next time this happens try just signing out/in of Facetime (in the Facetime Preferences window) then make sure the phone call option is checked. Works for me. I suspect this is a bug that needs squashing in a future release.

I, too, had this same problem on both my 2.4g and 5g networks, and when I went into the Apple Store Genius Bar to try to solve it, everything worked fine [ever go to the Doctor and the aches and pains suddenly are no longer there until you go home again?], so I knew it must have been something in my home network(s).

I am using a Netgear (blech, but it's what I have] router/wifi. I dug into the Wireless Settings and discovered this:

Enable Wireless Isolation

With an explanation in the help of:

Enable Wireless Isolation

If checked, the wireless client under this SSID can only access internet and it can’t access other wireless clients even under the same SSID, Ethernet clients or this device. Other clients can’t access the wireless client, either.

Naturally, being security conscious, I had the check boxes for both networks ticked.

Unchecking them, and of course applying the changes, solved everything.

If you don't have Netgear (good for you!), look for something similar in your Wireless Settings on your router.

I was experiencing the same issue, I was getting the error message about my iPhone and Mac needing to be on the same wifi network.

I had to log out of FaceTime on all devices (MBA, MBP, iPhone, and iPad) and log back in. Although it did stop working when I accidentally changed the FaceTime outbound caller ID as my Apple ID email address instead of my phone number (as it is on all other devices). I ended up having to log out of FaceTime on all devices and log back in again. Caller ID is set to my phone number on all devices and I can now make/receive calls on all devices. Seems to be working again. I actually think this all worked better during the beta.

And it stopped working again the next day! No matter what I do, I just can't get this feature to work consistently. COME ON APPLE!

iOS

Settings

FaceTime (FaceTime on/green & iPhone Cellular Calls on/green)

check your phone number & e-mail

OS X

FaceTime

Preference (check all 4 boxes)

on your iOS device (if you have a Apple router)

open up AirPort Utility (app) & restart the Base Station

fixed my connections problems

iPhone 6 Plus 8.1.1

MacBook Pro 10.10.1

AirPort Extreme 7.7.3

Hi All,

I have found what can block this feature !

In the Security&Confiditialiy, on FireWall settings / Options :

DO NOT CHECK TO BLOCK ALL INCOMING !

Only the two checkboxes below can be checked.

I have the same problem now too. It worked this morning, and then just stopped.....and I can't get it to work again. 😟

Had the same problem. Mine solved with router restart.

iMac 5K with iPhone 5S and both are connected to an Airport Extreme 2014. I was able to make and answer calls on the iMac with no problems (other than the Mac would keep ringing if i didn't answer, even after the person eventually hung up, the mac would keep ringing, but that's another story). Taking calls on the mac worked fine, then all of a sudden it started giving this same error "Your iphone and mac must be on the same wifi network". I've tried everything thing suggested here and it does not work.

I suspect it may be because one device is on the 2.4Ghz and the other is on 5Ghz band on the Airport Extreme? but how do I tell which device is on what?

In Airport Utility, you can configure your 5GHz band to have a different SSID.

Thanks! will try this

So I just bought a macbook pro and I'm having the same issue.

I have an iPhone 5 with 8.1.3 software (newest version at this time), and my macbook pro has OX S Yosemite 10.10.2.

I called Apple support and they resolved the issue - kind of.

My router has 2.whatever and 5.whatever bands. When my iPhone and Macbook Pro are connected to the same band, I get the message saying that the iPhone and Mac must be on the same network. Interestingly when I put either my iPhone or Mac on the 2.4 band and leave the other on the 5 band, I'm able to make calls and I don't get any error messages.

Maybe this is some kind of an issue in my router setup, I'm not sure. I have a Netgear router, and as someone else previously mentioned, the Enable Wireless Isolation checkbox on both bands are unchecked and have always been unchecked. Apple said something about port forwarding in port 500, which is used for wireless calling.

Offering my five penneths worth, I think the problem is intermittent. I have:

- Checked all my ids

- Made sure that the firewall allows incoming for FaceTime (by setting it up)

- restarted my Apple Time Capsule which is my router.

Nothing - can receive calls on my mac, couldn't send it. Then just before replying to this, my router went off the air for a brief second by itself. I then made a call (accidentally) and it worked.

So I am not sure what is going on but I am just going to treat this functionality as plaything until I know more. I think it is useful though.

Hi....I found the solution to this on my MacBook Pro running OS X Yosemite and now everything is working perfectly and reliably.

In the days after installing Yosemite on my MacBook, and before I even went to set up Continuity features and iPhone dialing from the Mac, I received a few pop-ups asking me to allow incoming connections for several system services. I was not doing anything that would have caused these pop-ups to show up at that time so I denied incoming connections for all of them because I didn't know what they were for.

Fast forward a few weeks and I was trying to set up Screen Sharing so that I could help my father with his Mac remotely, and we could not get it to work for the life of me. Kept getting connection errors, which eventually led me to the thought that all of those services I denied access to in the Mac firewall a few weeks earlier might be needed for Screen Sharing in the Messages app.

So I went into the Mac firewall and Allowed incoming connection on the following services:

Screen Sharing (enabled in Sharing in System Preferences)

awacsd

coreaudiod

FaceTime.app

identityservicesd.app

kdc

launchd

Messages.app

NETserver.app

sharingd

Not only did this get Screen Sharing working, but the iPhone calls from the Mac started working too. And it has stayed working since. Some of these are clearly related to the Screen Sharing feature so I can't identify which ones specifically got the iPhone/Mac calling working....but one or more of them certainly did because it only worked after I did this.

I did not change any setting on my modem or router.

I hope this helps someone out there because iPhone/Mac calling is pretty convenient....
