Have you waited long enough for the PC to specify its address?
If the PC cannot find a server in the network, the search for the server looks in the
DHCP setting (Obtain an IP address automatically) first of all. (The icon for the
interface in the Windows 7 tray indicates the search, but the icon might only appear
if it is configured to do so. In Windows 8 and higher it is no longer displayed.) It then
takes about 30 seconds before an automatic address or the specified alternative
address (if any) is set. No device is found during this time.
•
Is it possible that your firewall is blocking the connection?
Try deactivating your firewall or open the following ports:
•
For communication with the device via a browser, TCP ports 80 and 8081 are
required.
•
Different ports are required to locate the ClipX depending on the variant. For
UPnP TCP 80 and UDP-Multicast at IP address 239.255.255.250 (sending and
receiving) with port 1900, for NetBIOS UDP 137, for Avahi or Zeroconf (similar
to Bonjour) UDP-Multicast is required at IP address 224.0.0.251 (sending and
receiving) with port 5353.
•
If a WLAN is also active with your PC, test whether the device is found when you
temporarily switch off the WLAN (only for the time of the scan). With some WLAN
configurations, problems can occur if multiple Ethernet ports are enabled.
•
If your PC has several Ethernet interfaces, try deactivating all other Ethernet inter-
faces.
•
If you are using the device in a large network, contact your network administrator.
There are a series of options in managed networks to limit or completely prevent
data transmission between the individual nodes. Administrative access control set-
tings may therefore by needed here.
Notes
•
In Windows XP only the name resolution under NetBIOS is available.
•
For name resolutions via NetBIOS, you should only ever connect one ClipX as long
as you have not changed the device names.
•
UPnP is only available as from Windows 7.
•
Avahi or Zeroconf (similar to Bonjour) is only available if a corresponding service,
such as Bonjour print services, is installed.
