Changing the IP address of the DVB Net source
The final step is to set the address of the network interface to the DVB source to the standard value used by the TelliCast software. Please note that the device names may be slightly different. For example, the SkyStar2 DVB PCI card has a name TechniSat DVB-PC TV Star PCI, whereas the Dexatek USB box has a driver name: DVB Net ETAdapter.
For Windows Vista and Windows-7, using the Control Panel, navigate to the Manage Network Connections (in Windows-7, Change Adapter Settings) page:
Now look for Change adapter settings (Windows-7) or Manage Network connections (Vista).
XP - for Windows XP, use Control Panel, Networks, to list the network connections:
Double-click on the DVB Net ETAdapter, and press the Properties button. The Windows Vista / Windows-7 and Windows XP dialogs are quite similar.
Select the Internet Protocol Version 4 (TCP/IPv4) line, and click Properties. With Windows XP, select the Internet Protocol (TCP/IP) line. On Windows Vista and Windows-7, I suggest unchecking the TCP/IPv6 box.
Select "Use the following IP address", and enter 192.168.238.238 for the IP address. Click on the Subnet mask field, and it will automatically be filled in as 255.255.255.0.
Click OK, and then click Close on the status dialog.
On two Windows-7 boxes I have found that the IP address you enter may not "stick" from one reboot to the next, and you get an address starting 169.x.x.x instead. One workaround I found to this problem was to use the Advanced option in the dialog box above, and add a second IP address of 192.168.238.239 - just one higher - and then edit the TelliCast recv.ini to use that new address. Not quite sure exactly why this happens, except that it seems Windows is assigning an automatic address when it should not using APIPA. The cures suggested for Windows Vista do not appear to work in Windows-7. Any tips from the networking experts?
On Windows Vista and Windows-7, but not Windows XP, some people have reported problems with using a LAN and the DVB/TelliCast software at the same time. It appears that communication between the TelliCast software and the DVB software which should be internal to the PC is actually being sent over the LAN connection. As the DVB network interface is actually software inside the PC, and not hardware at the end of the LAN cable, TelliCast fails to work, being either stuck in the yellow T-icon state or, if the network cable is connected after the system was working, the icon alternates between the "pink" and "red" states.
To work round this problem, you need to tell Windows that the addresses handled by the DVB software must always be reached through the address which you set up in the step above. In the Start menu, All Programs, Accessories menu, you will find an item named Command Prompt. Right-click on this item, and select Run as administrator (as you want to make system changes). Enter the following command:
route -p -4 ADD 188.8.131.52 mask 240.0.0.0 192.168.238.238
Interpreted into plain English (?), the command line means: add a permanent route with IPV4 to force access to the multi-cast address 184.108.40.206 to go via the interface with IP address 192.168.238.238. The address 192.168.238.238 is the address given to the virtual network card created by the networking component of the DVB software (you set this earlier on this page). The address 220.127.116.11 is where the EUMETCast data appears to be coming from (and this is hard-coded in the Eurobird-9 transmissions). So we are telling the system that to receive EUMETCast data, you need to look for it on the DVB virtual network card, and not on the general Internet. Type Route alone for more information on the route command. Here is a somewhat edited session where I add the route, and then use the Route PRINT command to check that the route was added.
C:\Windows\system32>route -p -4 ADD 18.104.22.168 mask 240.0.0.0 192.168.238.238 OK!

[On a recent 64-bit Windows-7 install, I did not have this
problem. I had removed the IPv6 protocol from both the network card and
the DVB's network configuration, and that's perhaps why. Comments?]
Driver issue with 64-bit Windows-7?
The TechniSat drivers V4.5.1 work correctly with Windows-7.
One user reported being unable to change the IP address on 64-bit Windows-7 with version 3.0 of the DVB World driver, but this was cured by installing a 2008 version. Alberto writes:
There is a discussion of various
driver versions here.
Card loses address after a reboot
A couple of users have reported that the card loses its address following a reboot, going to an automatically-assigned address rather than the user-defined address (192.168.238.238). Ian Deans has reported that the second of the two solutions given here works for him. As it involves editing the registry, please take care, and consider creating a System Restore point before proceeding.
Windows-7 and IP V6 addresses
One other problem I have seen is that Windows-7 will assign an
IPv6 address to both the PC and the network device (the Dexatek/DVBWorld
software). Under these circumstances, there is both an IPv4 and an IPv6
path between the devices. If this causes a problem, you may want to
disable the IPv6 protocol on the Dexatek/DVBWorld device.
Computers with two network cards
There is another Vista/Winodws-7 (and Windows Server 2008) issue which may affect computers with two network cards - and it's possible that any EUMETCast computer falls into this category. See:
entitled: "The network connectivity status incorrectly
appears as "Local only" on a Windows Server 2008-based or Windows
Vista-based computer that has more than one network adapter".
