An unexpected error
I have an Airport Extreme Capsule 2T. It has been working fine, but it is not seen on the network. It will function as a pass thru for the internet connection. It does put out a wireless signal, but I can not get into it to reset the password. I tried the soft reset, but nothing seemed to happen. I tried the hard reset, but that requires a password.I asked airport utility to open it, but that said an unexpected error try again. Not very helpful. I have turn off everything on the network and rebooted everything. That did not change anything. I am running Le Capitan 10.11.5 the Airport Utility is version is 6.3.6. The Airport Time Capsule needs a firmware update, but I can not do that because I can not get into the Airport Utility program.
