I have an older Time Capsule. I think that it is about 8 years old. It is connected to a new Airport Extreme in extender mode (at least, I think that is what it is called when you use a second unit to extend the first - with the same SSID and passwords). I installed the Airport Extreme back in December and didn't have any problems for the first few months. For about the last 2 months, I am losing connection with the TC. I notice this when my MPB cannot run backups - it can't find the TC hard drive. The only way I am able to fix it is by unplugging the TC and then plugging it in again. I have to do that 1 to 2 times per week. The software for the TC is up to date. Any suggestions on how to fix this? I'm wondering if it is time to say thanks to the TC for time served and buy a new one.
