Q: Windows 10 with aiport utility v 5.6.1 doesn'see my device, Win 7 was ok

Use ethernet or use an ethernet to wireless bridge. Don't use wireless.

And do the setup on iOS or Mac not a PC.

Windows 10 device drivers can show they are working and be absolutely a total failure.. you do know that??

Also windows X is having issues with apple routers as a whole.

Do a search for win10 and apple routers.. in this lengthy post Apple said they are aware of incompatibility.

PC can read time capsule but can't write

dhinfo12, you are the 4th Windows 10 user with problems I've seen here in the past week alone.  The problems vary and I am curious what your experiences are, as follows:

• In my case, AirPort Utility running on Win 10 is unable to detect and render a graphical display of my network devices.  At least reliably, i.e., sometimes it works, sometimes it doesn't.  How about you?

• Others report not being able to see their Time Capsule (TC) at all as a network device within This PC.  You?

• Othere report being able to see their TC, can Read from it, but not Write to it.  And again, you?

Knowing more about your experience helps to understand the scope of these Windows 10 issues.

Apple has not updated the AirPort Utility software for Windows in over 3 years.  The current (and latest version) of AirPort Utility for Windows officially supports Windows 7.....and nothing higher.

If Apple has not bothered to update the Windows software in any way in well over 3 years, my opinion would be that they are not ever going to do this.  But, I could be wrong.

The only way that you will know for sure is to contact Apple Support directly and ask them about this.

I have not had positive things to say about Windows since XP.  But with this new release of Windows 10, I have to say I am impressed.

Microsoft has gone the extra mile to play with iOS and OS X.  For instance,  automagically during the upgrade process Win 10 detected, downloaded, and synced my Apple Calendars and Contacts with it's Window's counterparts.  And now keeps them in sync.  I had iTunes installed on Win 7 before the upgrade...that's all 10 needed.  Nice!

Apple should take heed.

Older TC have problems with IPv6. 

the easiest way to get your Windows 10 machine to see your TC or Airport Express is to disable IPv6 on windows.  You do this by going to:  Control Panel -> Netowork and Internet -> Network Connections

Then right click on whatever network adapter you are using to connect to your Airport Network of devices, and click on properties.  This will bring up a menu of configuration options for that adapter.  Just uncheck the checkmark next to Internet Protocol Version 6 (TCP/IPv6).  Hit OK, reboot your machine, and run your airport utility.  You should see your TC and ape devices.

(note, if you need tcp/ipv6, then you'll need to do some more research into the 'type' of tcp/ipv6 network you need to run.  Note, you may also have to go into your airport router and make sure you don't have any ipv6 servers or domain names specified.  Also, your airport devices need to have their ipv6 mode set to Link-local only)

Hope this helps...

if you need tcp/ipv6, then you'll need to do some more research into the 'type' of tcp/ipv6 network you need to run.

Generally it is not a good idea to turn off IPv6 now.. Windows needs it for home group.

And all you really need is to set to link-local only. That is sufficient.
