I’m unable to get Time Machine to back up to my Airport Capsule, suggestions? It was working fine until this fall.
MacBook Pro, iOS 11.2.6
Ok, thanks for the update on the modem. If you got your Time Capsule (TC) new in 2012, then it most likely is a 4th generation 802.11n "flat" model. The latest versions are "tall." Regardless, it's important to understand that most consumer-grade networking hardware have a useful lifespan of between 3-5 years. I'm not necessarily suggesting that your TC is faulty, just making you aware of that bit of information.
What I would suggest at this point in time is to perform a "factory default" reset on your TC, and then, set it back up for your networking goals. Note that performing this type of reset does NOT affect any data stored on its internal (or external) hard drive(s).
After you have it back up and running, see if Time Machine continues with its backups.
Did you upgrade to macOS Sierra in the fall? Which exact model is your Time Capsule? Is it the only wireless router in your current network configuration? What is the make & model of the Internet modem or gateway that yo have the Time Capsule connected to by Ethernet (wire) to gain Internet access with?
I only started experiencing this problem at the end of November 2017. My router is Arris MTA. Model TM602G. I have to look up the model of my Time Capsule, I know I got it in 2012. I use Spectrum for Internet Service. It is the only device I am using and until November I could back up wirelessly.
i will try this solution later and get back with you. I appreciate your help and suggestions.
Time Machine won’t back up with Sierra. I use a Capsule, and when I enter to say back up, which takes an extremely long time, I get a message that the back up was interrupted
