if you have problems connecting your pix-star to a Zyxel c1100z supplied from Centurylink check this:
log into the config panel of the router and go to the wireless section check that the security is set on:
WPA2 with AES encryption.
Sometimes this router is set with
WPA/WPA2 mixed mode
which in this case may not work with the frame.
AES is by the way the safest configuration.
