TC no longer a part of my network but my wifi network is still working, mostly. What has happened?

we solved the problem but not the rootcause. It seems Apple requested us to submit a ticket to make the issue clear to the engineers. The workaround makes local networks manageble again, so far I have not missed the iCloud feature, a networkdrive takes care of shared files.

I also created a ticket about that kind of problem. Apple engineers were solicited to have a look on it.

Waiting for their answer.

Removing Apple ID is currently the solution, thanks for the tip !

I got the same problem. Removing Disable Back to my Mac function help... but I don't think this is right solution.

Sure it's not the solution, but currently it seems to be functional.

Waiting for update of Apple Engineering...

So how do I login with the configure other function?

"Address" is what?

- Router IP address?

"Password" is what?

- Wifi password?

- Specific router password?

If you need step by step instructions see AirPort Utility: AirPort Device not Found with Firmware 7.6.7 or 7.7.7.

I have just hit this problem. Airport Utility (on all devices) says "Device not found". Tried reboot and it re-appeared for a few seconds then went again. Internet router and wi-fi part seems to be working but not internal Time Machine disk nor attached USB disk. I have seen the fix/work-around but don't understand what it means. Can someone go through it step by step.

I see that someone has done that while I was typing my question - thanks.

Many Apple users choose Apple because of it's simplicity in use and setup. IP retrieval may be a bridge too far. Another way of disabling the BTMM is to unplug the WAN-cable and restart the devices. The devices will show up without the iCloud connection. Unplugging and restarting is for some users easier then hunting down IP adresses. Don't forget to replug the WAN-cable. Cheers!

Lets see if this works, can't connect to my router using the "configure other" option.

I get an error... (An error occurred while reading the configuration)

Unplug your TC and plug it back in to reset it. Open your Airport utility. When the TC comes up you will have a few minutes to edit your settings. Double click the Time Capsule Icon and then hit edit. Under the Base Station tab delete your Apple ID in the Back to My Mac section. Then hit update to update your TC settings. This is not the final solution but until Apple gets off their *** and figures it out this will have to do.

Wonderfull, thank you. The problem gone within 1 minute

@MurgenTemplar solved your problem, but not mine. I have the same issue, but I don't know my TC's IP address. Therefore this "solution" is no good to me. Any other advice, @MurgenTemplar?

This works! Thanks. Now to wait for a true fix from Apple...

You can find your TC IP address. It kind of depends on your setup but the easiest method is really to reset the TC to factory and then use a static IP.

No files are lost on the TC disk doing this.

Factory reset universal

Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.

N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.

Setup the TC again.

Then redo the setup from the computer you want to use for TM using Airport Utility.

1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.

eg TCgen5 for basestation and TCwifi wireless name.

If the wireless is still a problem set wireless names like TC24ghz and set the 5ghz to different name.. eg.TC5ghz

2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.

**3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.

Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC.

Ignore this point if you don't understand it .. post back if you have drop out issues.

4. Make sure IPv6 is set correctly in the computer. ie link-local only for ethernet and/or wireless depending on which you use. Auto is not good enough.

If your TC is main router it has an IP of 10.0.1.1 by default unless you change it.

If your TC is setup in bridge mode then I recommend you swap to static IP.. you can do this by simply changing the Internet tab to static and give it the same IP it is getting now.. once you do the full reset above it should appear in the airport utility at least for a few minutes to accomplish this. You should also use the current DNS servers which are not necessary in bridge but will stop the error message.

I actually run a slightly different version of static IP which has been more reliable. You will need to do a bit more setup though.
