Let me fix the above statement for you....
"We have done every test known to the direct TV technician and they all say that the system is connecting but it will not work"
Being as how he's a TV tech and not a computer or network tech, this doesn't mean the two of you have done every possible test. Unless of course you're a computer/network technician.
From what you say, and to add to what phil22 said above, it's more likely a cable problem (as per phil22) or the issue is the configuration on your TV.
Are you attempting to connect the TV to the LAN with it set as a DHCP client? If so, you will want to compare network settings to that on your laptop. Everything but the IP should be identical. Which is to say, the Default Gateway IP and Subnet Mask should match. If either of those is different on the TV, that's most likely your problem.
If that is the case, then you should try statically assigning TCP/IP settings to your TV. Check the DHCP Scope on your router and ensure you pick an IP outside the scope (so as to avoid potential duplicate IP conflicts) and use the exact same DG/SM as shown in the DHCP settings. Note: you can check your laptops TCP/IP settings (for comparison purposes) by opening a command prompt window (Start >> Run >> type cmd and hit Enter) and performing the following command:
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
