All I want to do with my Time Capsule is use it to back-up my work. I don't care about wifi networks or base stations or anything else I neither need nor understand. Because I preferred to keep it out of sight, and away from my work area, I plugged it into my BT broadband box and it seems to be working fine via wifi, accepting hourly backups from Time Machine. But after it (inexplicably) failed twice (I think because of a fleeting broadband issue, perhaps) and I had to back-up from scratch using an ethernet cable, I have decided to keep the Capsule on my desk and permanently tethered to my iMac via ethernet cable. It is working, but for the life of me I can't stop the irritating light on the front of the box flashing yellow at me. Can anyone advise what to do - other than taping it over???
