Give me a few screenshots of the setup.. grasshopper.
I have a Time Capsule (A1409 - 3TB) that is blinking yellow.
Open the airport utility and click on the TC.. and show me the summary page with the errors. There might be one or several.. I need to see them all.
Edit .. this is out of sequence because if you cannot find the TC in the airport utility you need to do a full setup and then fix it up.. so this is only if the points below fail. However if you run airport utility on iOS device eg ipad it might show you what is wrong.. There is plenty of issues now as the TC ages.. and gen4 can go bad pretty suddenly.
I have run a Hard Reset, however, the Airport Utility doesn’t find the TC.
You have network issues.
Are you running ethernet or can you change over to ethernet please do so.
The TC must be detected by the airport utility.
If not and to get the above screenshot.. clearly you cannot find out the problem if you cannot get to TC in the utility.
Do a factory reset.. no files on the disk are harmed.
Follow this.
Start from a factory reset. No files are lost on the hard 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 with Mavericks--Yosemite--ElCapo. (MYELCAP)
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 for basestation and TCwifi wireless name.
If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
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. But this is important.. having IP drift all over the place when MYELCAP cannot remember its own name for 5 min after a reboot makes for poor networking.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the computer itself. eg Reset the NVRAM/PRAM/SMC.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Should I have “Removed Disk” in ‘Select Disk” in Time Machine (in Preferences) before doing the Hard Reset ?
Get the network up first before worrying about it.
How does the TC have 3TB used when the iMac only has 484M used ?
If the network connection to the TC has failed this may not be valid..
If it is then it is easy to use 3TB if you have any virtual disk on the Mac.. ie you dual boot windows or have any cloud cache.. anything that will use a large file that will be replaced for minor changes.
