Philips NetTV and FritzBox 72xx

I recently bought a new LCD TV from Philips : The 47″ PFL8404H/12 with NetTV.


Philips 47 PFL 8404 H 119,4 cm (47 Zoll) Full-HD Ambilight LCD-Fernseher mit integriertem DVB-T / DVB-C Tuner schwarz

Actually, I chose this TV because of two features it has:
1. The display : Full HD, 47″ , non reflective having the “Pixel Precise” feature
2. the Net TV: which means practically the you have an Internet connection in your TV set.

I have the FritzBox! 7240 from AVM which is a goot DSL modem and router.

The problem

However, after installating the TV and connecting it to the Internet I noticed that it looses, apparently randomly the connection to the router.
When connecting the old FritzBox 7170, everything worked as expected.

The reason

All FritzBoxes have a nice feature which tries to make the device eco friendly (aka “green”) by reducing the power consumption.
So, it has some automatic detection if a LAN port is used or not.

The Solution
After discussing with Heino, a colleague from Avira, he gave me an idea: what if the automatic detection of the LAN ports is not functioning correctly ?
And he was right.
Apparently, this automatic detection is not working correctly and it deactivates the port way to soon.
I deactivated the automatic detection by configuring that the ports must be always enabled and now everything is working perfectly !

And NetTV is a great feature !!!
YouTube on a 47″ TV is a nice thing. Or at least my 2 years old son thinks this when he is watching his Pluto cartoons.
