I have the previous gen 2 TB Time Capsule. The WiFi on it seems to crap out about once a week. The front light remains green, but even after just letting it sit for up to 15 minutes, the WiFi to all devices seems completely dead (oddly, the 2 wired devices still work during that time). I have to them pull the power plug on it, wait 15 sec, plug back in, and then in a couple minutes all back to normal. Firmware and everything seems to be current. Is it something that the "Genius" bar can help me with? It's happened 4-5 times now over the past month. My previous AEBS I think remained on and stable for 5-6 months straight at a time.
