If your Wi-Fi router is Wi-Fi 802.11n
FHUWLÀHGPDNHVXUHWRHQDEOHWKH
802.11b/g mode. DS9800W does not
support connection to routers with
802.11n only.
This device does not support the WPS-
PIN method.
If your Wi-Fi router supports WPS and
the WPS-PBC method but fails to connect
to DS9800W, try the manual Wi-Fi setup
method (see 'Scenario 2: Connect to a
non-WPS router' on page 13).
Enable SSID broadcast on the Wi-Fi router.
Keep away from potential sources of
interference which may affect Wi-Fi signal,
such as microwave ovens.
If you fail to use your PC for Wi-Fi network
setup, check whether your PC is using a
Wi-Fi network. You cannot use Ethernet
connection for AirPlay network setup.
Make sure that the SSID name of your
home router consists of alphanumeric
characters, with no space or special
characters like %/#/* inserted.
If you choose to rename the AirPlay device
'Philips_Fidelio XXXX' in the setting menu,
do not use special characters or symbols.
For some new types of Wi-Fi routers, a
network name (SSID) may be created
automatically when you use WPS for
connection. Always change the default
network name (SSID) to a simple one that
consists of alphanumerical characters, and
also change the Wi-Fi security mode to
secure your network.
