The Homematic IP WLAN Access Point works in the
2.4 GHz frequency range. Operation in 5 GHz frequen-
cy range is not possible. Therefore, make sure that your
smartphone is in 2.4 GHz frequency range while setting
up the Homematic IP WLAN Access Point. If this is not
the case, deactivate the 5 GHz frequency range of your
WLAN router during setup.
