absolute retrogression, and a bad product

I can set up a connection with the Capsule just 1x, then run all the devices.
Great.
Now after a few hours, I'll dial again that worked previously yes in my wifi, but he asks me again for my password.
Although I enter the password correctly (before that I had brought with it different devices into WLAN) no longer works this password now.

Rough disappointment from this unit. I give a lot of money and now I can not use it, or must first press the reset button again and may set up everything again, or restart.

I'll look for another manufacturer, the WLAN products make too many problems.
My Airport Express way, had repeatedly connecting terminations, since the latest update 7.6.4 has been resolved, however. What, however, probably does not apply to the reconnect of Apple products at this Time Capsule. Here probably would have an update to wait. (Which I, however, now have no more desire, because my Express yes now but times funktionierier .. I'm just pretty upset about these devices sold and the controls ..)
Here are around a lot of WLANs and apartments, perhaps Apple is not compatible.

No recommendation.
