Well this is my history, a Samsung Tech came into my place because my ES7500 sometimes lost the connection, the TECH told me that I need to put my dls modem close to my TV but the TECH made some test on my TV he enter into the service mode and move the WIFI region, Now it's worst, so anyone can help me with this one? I need the default WIFI region to put it back on my TV Thanks!!

1st Law of the Universe: Don't ever let a Samsung Technician into your house.
2nd Law of the Universe: Entropy is always increasing, because of the existence of (Samsung) technicians.
3rd Law of the Universe: Don't ever let anyone mess with your TV, not even god.

Use inSSIDer to check that your wifi channel is not colliding with the rest of the neighborhood...
