General Help guidelines:
If you have trouble connecting the 851N to your network, these steps may help to
resolve the problem:

• Confirm that a connected computer can access the Internet (i.e. can browse the
web) using the same network.
• Check that a DHCP server is available, or that you have configured a static IP
address on the 851N. You can configure a static IP address on the 851N using
the menu item ‘Settings -> Network Config -> Edit Config’, and then select ‘No’ for
‘Auto (DHCP)’. DHCP is however the recommended method.
• Check that your network’s firewall is not blocking any outgoing ports. As a
minimum, the radio needs access to UDP and TCP ports 80, 5 54, 1755, 5000,
6000 and 7070.
• Check your access point does not restrict connections to a particular MAC
addresses. You can view the radio’s MAC address using the menu item ‘Settings
-> Network Config -> View Config -> MAC address’.
• If you have an encrypted Wi-Fi network, check that you have entered the correct
key or passphrase into the 851N. Remember that text-format keys are case
sensitive. If, when attempting to connect to an encrypted network, your 851N
displays: ‘Wireless error’ followed by a 5-digit number, then please ensure that
you enter the correct passphrase for the network. If the problem persists, then
you may need to consult your network configuration.

are trying to access. Some servers do not serve FLAC for instance.
• The 851N can only play non DRM files. Files that have DRM controls cannot
be played by the 851N. Some servers may be able to authorise and de-crypt
Microsoft Playsforsure before then serving the content to the 851N but this
operation is not guaranteed as it is purely a function of the server.
• If attempting to play 24-bit WAV or FLAC content note a wired Ethernet connection
is normally required for reliable operation due to bandwidth considerations.
• Check the 851N is capable of playing back the file type you are trying to access.
WMA, AAC, MP3, Vorbis, FLAC and WAV can currently be played. The 851N does
not support ALAC, WMA Pro, WMA lossless, RAW, AU or other file types not

• The way you organise your USB media affects the size of internal database the
851N needs to build dynamically as you browse content. Good practice is to
create folders for Artists within which you should have a sub folders for each
Album which then containing the tracks for that Album. Libraries with thousands
of tracks in one folder will progressively slow down the 851Ns media browsing.
