Can't access Airport Extreme after Yosemite install.

I have had the same problem after updating to Yosemite 10.10.1.

If I do a ping for my airport I get what appears to be a self-assigned IP address returned: 192.168.1.254

I tried the following workaround - extreme is my airport extreme device name:

I entered the IP Address for extreme.local and extreme in /etc/hosts.

192.168.1.254 extreme extreme.local

I then used finder "Connect to Server" and connected to smb://extreme

This worked.

This is not an ideal work around but it seems to be a crude patch to the problem which probably points to an issue with Bonjour and networking.

I know, it's the first time I've even WANTED to go to my iTunes in a long time, and now I have to use AIRFOIL, a 3rd party app, to make it stream through my airport express (at least the 3rd party app is cool enough to let me use volume buttons on the keyboard, unlike clunky ol' iTunes!)!

Turning off Wake for Network doesn't work neither..

I just hook back my printer to the iMac for now. Frustrated.

The IP you mention is not self-assigned. It's just a non-routable IP address that home wifi routers give to machines that are connected to them via Wifi.

If you see an IP like this: 172.16.x.x, that is self-assigned.

I'm getting the same problem too. Firewall is off, and so is Wake on Lan (although, I don't see how this last setting would fix the problem).

My feeling is Yosemite uses different Unix file permissions, and those aren't lining up with whatever permissions are on the shared volume.

Or, they're not propagated through AFP://

I think if you directly connect the USB drive to your 10.10 mac, you should see your files again. I will check this later.

Hello everyone, I see I'm not alone with this issue 🙂

To make it clear: it came with 10.10.1 update. Before everything was working fine. And it's Yosemite's fault for sure because the problem happens only on my MacBook Pro and my girlfriend's MacBook Pro. AirPort utility and Time Capsule access work fine with iPad and iPhone.

I tried to delete all Passwords related to AirPort and Time Capsule in my Keychain, then I reset Time Capsule to factory settings, same issue.

Sometimes Time Capsule is green in AirPort Utility and I'm able to access the disk in the finder. And sometimes (although visible) it's grey in AirPort Utility and unable to connect from the finder. The problem seems to happen randomly. Sometimes I can access it, sometimes I can't.

I noticed that the Time Machine Backups are working well, even when my MacBook Pro is in sleep mode with power nap.

I tried the suggestion to turn off "Back to my Mac" both in my iCloud account and in Time Capsule settings. It seems to have solved it from this morning and it's almost 6PM here (Paris Time). And while writing I'm checking my AirPort Utility from my Mac: Time Capsule is Green.

I guess we will have to wait for an update from Yosemite or Time Capsule firmware. Who knows...

Thanks! This worked for me first time..

- Airport utility showed a green light next to internet, but only a loading spinner where the AP bas station should be

- With AP Utility open, I switched Wifi off, then on again

The Base station appeared immediately, and I can now access my remote disks!

Many thanks

PS, I notice that Firewall was off when I did this. I've switched it on since, and I still have access to the Base Station and it's attached drives.

Been having the same issue since I purchased my Airport Extreme a few weeks ago. Tried this;

Disabled wake-from-sleep for network access.

and I was able to connect immediately.

Thanks for the tip!

Disabled wake-from-sleep for network access, and my hdd access for time machine backups on a "wired" airport base station extreme began working again. This only impacted my mini with 10.10.1, and not an my old imac on 10.7.5 (yes, i know, both using the same usb hdd on airport extreme for time machine is not recommended, but I have been doing for years, and it always works\restores without issues.. until 10.10.1..., even though I really only needed a restores 2-3 times... they worked, so I keep doing it this way). Disabled wake-from-sleep for network access on mac's using 10.10.1, reboot, celebrate.

I read all of this and here's what worked for me:

1. "discoveryd" was blocked in Advanced Firewall. I unblocked it.

2. "Stealth Mode" was checked in Advanced Firewall. I unchecked it.

Suddenly, I would see my (older) Airport Extreme Base Station/Time Capsule, as well as the two USB attached Time Capsule drives.

I rebooted the Time Capsule, but it wasn't necessary, nor was rebooting my MacBook Air.

The Advanced Firewall setting changes above did the trick immediately, not reboots needed.

This mess had me stumped for months.

I've been following all these posts. My trouble be an with Yosemite as well. IntermittentLyn lost contact with my Canon 922 printer and over time realized it wasn't the printer itself. Couldn't see the Airport Expreme with airport utility from my Mac but could from my iPad and iPhone however couldn't airpri from them! Rebooting any of these devices were only a temporary fix with the problem recurring in a variable way. What seems to have fixed it was going to firewall settings and explicitly adding permission for Bonjour and the Airport utility. All problems have disappeared. Keeping my fingers crossed to see if a durable fix. Thanks to everyone's suggestions.

Don't know if this helps , but after the Yosemite update i couldn't 'see' my airport extreme base station in airport utility on my MacBook Pro, but was able to connect wirelessly to the internet. Read with interest all these suggestions, none helped. Finally noticed that under sharing I had checked 'share screen', for no reason i could remember. After I unchecked it, i was now able to see my base station. Very strange. Hope this helps someone.

IPV6 to Link Local fix resolved my issue of basestation not appearing in airport utility on 10.10.2

Try your iTunes password. I was using what I thought was my Airport Utility password, and I just tried my iTunes password and it worked.

Before 10.10.3 I was not able to see/login my airport extreme in airport utility even in the cases where I had internet connection. Now in 10.10.3 I can at least login to review/change airport settings, but the usb drive connected to the airport base station is still not visible.

I have had Yosemite since it came out, and I recently bought an airport extreme (my first Apple router). I had some trouble getting it to recognize my Canon printer, but setting a static IP fixed that. Everything seems to be fine. All of a sudden, 2 weeks later, my 2 external network hard drives will not show up in finder, although other devices - Sony Bluray player, iPhone - still access them. Tried resetting, reinstalling, etc., etc. Finally, merely disabling wake for network access seems to have worked. Bizarre, especially since they had all worked fine for some time until yesterday. Thanks for digging.
