I am having a problem with my time capsule backing up my computer. The wifi (airport) is working fine, but the computer is having trouble locating the disk to back up. Says that it can't find the connection to the back-up disk. Tried to remove the disk and set up my time capsule from scratch, but now I can't select disk altogether to set up the time capsule. This has been happening ever since I upgraded to the 10.10.2 beta (didn't want too, but it auto-updated for me). Has anyone else had this problem and do you know of any possible solutions?
