Time Capsule not doing its job

[l0renz]

Hi

When my MacBook Pro is connected to my Time Capsule's Wi-Fi and try to join this network with my iOS devices (iPhone 5 & iPad 4), it doesn't stop 'connecting'.
So I unplug the Time Capsule its power, make my iOS devices join the Wi-Fi network and after that my MacBook. In this case there seems to be no problem, it's only annoying I always have to unplug the cable...
Anyone having the same kind of trouble?

Thanks

Are all devices up to date? (Time Capsule v7.6.3, iOS v6.1.3)

Is the TC the only wifi node on your network?

Is the TC your only router device?

All up to date!
The TC is the only node on my local network

No it's pretty complicated, my TC is connected to an ethernet cable of my school campus, which always requires a log-in to get internet (each student has a data limit).
Thanks!
